otherwise the name in the archive is used. +If multiple files in the archive have the same name, and paths are listed +on the command line to ``select'' archive files for an operation, only the +.B first +file with a matching name will be selected. +.PP +The normal use of +.I ar +is for the creation and maintenance of libraries suitable for use with +the loader (see +.IR ld (1)), +although it is not restricted to this purpose. +The options are as follows: +.TP +\-a +A positioning modifier used with the options \-r and \-m. +The files are entered or moved +.B after +the archive member +.IR position , +which must be specified. +.TP +\-b +A positioning modifier used with the options \-r and \-m. +The files are entered or moved +.B before +the archive member +.IR position , +which must be specified. +.TP +\-c +Whenever an archive is created, an informational message to that effect +is written to standard error. +If the \-c option is specified, +.I ar +creates the archive silently. +.TP +\-d +Delete the specified archive files. +.TP +\-i +Identical to the \-b option. +.TP +\-m +Move the specified archive files within the archive. +If one of the options \-a, \-b or \-i is specified, the files are moved +before or after the +.I position +file in the archive. +If none of those options are specified, the files are moved +to the end of the archive. +.TP +\-o +Set the access and modification times of extracted files to the +modification time of the file when it was entered into the archive. +This will fail if the user is not the owner of the extracted file +or the super-user. +.TP +\-p +Write the contents of the specified archive files to the standard output. +If no files are specified, the contents of all the files in the archive +are written in the order they appear in the archive. +.TP +\-q +(Quickly) append the specified files to the archive. +If the archive does not exist a new archive file is created. +Much faster than the \-r option, when creating a large archive +piece-by-piece, as no checking is done to see if the files already +exist in the archive. +.TP +\-r +Replace or add the specified files to the archive. +If the archive does not exist a new archive file is created. +Files that replace existing files do not change the order of the files +within the archive. +New files are appended to the archive unless one of the options \-a, \-b +or \-i is specified. +.TP +\-T +Select and/or name archive members using only the first fifteen characters +of the archive member or command line file name. +The historic archive format had sixteen bytes for the name, but some +historic archiver and loader implementations were unable to handle names +that used the entire space. +This means that file names that are not unique in their first fifteen +characters can subsequently be confused. +A warning message is printed to the standard error output if any file +names are truncated. +(See +.IR ar (5) +for more information.) +.TP +\-t +List the specified files in the order in which they appear in the archive, +each on a separate line. +If no files are specified, all files in the archive are listed. +.TP +\-u +Update files. +When used with the \-r option, files in the archive will be replaced +only if the disk file has a newer modification time than the file in +the archive. +When used with the \-x option, files in the archive will be extracted +only if the archive file has a newer modification time than the file +on disk. +.TP +\-v +Provide verbose output. +When used with the \-d, \-m, \-q or \-x options, +.I ar +gives a file-by-file description of the archive modification. +This description consists of three, white-space separated fields: the +option letter, a dash (``-'') and the file name. +When used with the \-r option, +.I ar +displays the description as above, but the initial letter is an ``a'' if +the file is added to the archive and an ``r'' if the file replaces a file +already in the archive. +.IP +When used with the \-p option, +the name of each printed file, +enclosed in less-than (``<'') and greater-than (``>'') characters, +is written to the standard output before +the contents of the file; +it is preceded by a single newline character, and +followed by two newline characters. +.IP +When used with the \-t option, +.I ar +displays an ``ls -l'' style listing of information about the members of +the archive. +This listing consists of eight, white-space separated fields: +the file permissions (see +.IR strmode (3)), +the decimal user and group ID's separated by a single slash (``/''), +the file size (in bytes), the file modification time (in the +.IR date (1) +format ``%b %e %H:%M %Y''), and the name of the file. +.TP +\-x +Extract the specified archive members into the files named by the command +line arguments. +If no members are specified, all the members of the archive are extracted into +the current directory. +.IP +If the file does not exist, it is created; if it does exist, the owner +and group will be unchanged. +The file access and modification times are the time of the extraction +(but see the \-o option). +The file permissions will be set to those of the file when it was entered +into the archive; this will fail if the user is not the owner of the +extracted file or the super-user. +.PP +The +.I ar +utility exits 0 on success, and >0 if an error occurs. +.SH ENVIRONMENT +.TP +TMPDIR +The pathname of the directory to use when creating temporary files. +.SH FILES +.TP 14 +/tmp +default temporary file directory +.TP 14 +ar.XXXXXX +temporary file names +.SH COMPATIBILITY +By default, +.I ar +writes archives that may be incompatible with historic archives, as +the format used for storing archive members with names longer than +fifteen characters has changed. +This implementation of +.I ar +is backward compatible with previous versions of +.I ar +in that it can read and write (using the \-T option) historic archives. +The \-T option is provided for compatibility only, and will be deleted +in a future release. +See +.IR ar (5) +for more information. +.SH STANDARDS +The +.I ar +utility is expected to offer a superset of the POSIX 1003.2 functionality. +.SH "SEE ALSO" +ld(1), ranlib(1), strmode(3), ar(5) diff --git a/usr.bin/ar/ar.5.5 b/usr.bin/ar/ar.5.5 new file mode 100644 index 0000000..29c8f8c --- /dev/null +++ b/usr.bin/ar/ar.5.5 @@ -0,0 +1,145 @@ +.\" Copyright (c) 1990, 1991, 1993 +.\" The Regents of the University of California.

If +.B \-w +is given, the output is scrunched down from a width of 132 to +.I n , +suitable for a narrow terminal. If +.I n +is omitted, it defaults to 80. +.PP +The output should be printed on a hard-copy device, up to 132 columns wide, +with no breaks between the pages. The volume is great enough that you +may want +a printer or a fast hardcopy terminal, but if you are patient, a +decwriter or other 300 baud terminal will do. +.SH BUGS +Several ASCII characters are not defined, notably <, >, [, ], \\, +^, _, {, }, |, and ~. Also, the characters ", ', and & are funny +looking (but in a useful way.) +.PP +The +.B \-w +option is implemented by skipping some rows and columns. +The smaller it gets, the grainier the output. +Sometimes it runs letters together. +.SH AUTHOR +Mark Horton diff --git a/usr.bin/banner/banner.c b/usr.bin/banner/banner.c new file mode 100644 index 0000000..6c8e560 --- /dev/null +++ b/usr.bin/banner/banner.c @@ -0,0 +1,1160 @@ +/* + * Copyright (c) 1980, 1993, 1994 + * The Regents of the University of California.

if none is supplied, the zero vector is used. +If no +.I key +is specified on the command line, the user is prompted for one (see +.IR getpass (3) +for more details). +.PP +The options are as follows: +.TP +\-a +The key and initialization vector strings are to be taken as ASCII, +suppressing the special interpretation given to leading ``0X'', ``0x'', +``0B'', and ``0b'' characters. +This flag applies to +.I both +the key and initialization vector. +.TP +\-b +Use electronic code book mode. +.TP +\-d +Decrypt the input. +.TP +\-F +Use +.IR N -bit +alternative cipher feedback mode. +Currently +.I N +must be a multiple of 7 between 7 and 56 inclusive (this does not conform +to the alternative CFB mode specification). +.TP +\-f +Use +.IR N -bit +cipher feedback mode. +Currently +.I N +must be a multiple of 8 between 8 and 64 inclusive (this does not conform +to the standard CFB mode specification). +.TP +\-k +Use +.I key +as the cryptographic key. +.TP +\-m +Compute a message authentication code (MAC) of +.I N +bits on the input. +The value of +.I N +must be between 1 and 64 inclusive; if +.I N +is not a multiple of 8, enough 0 bits will be added to pad the MAC length +to the nearest multiple of 8. +Only the MAC is output. +MACs are only available in cipher block chaining mode or in cipher feedback +mode. +.TP +\-o +Use +.IR N -bit +output feedback mode. +Currently +.I N +must be a multiple of 8 between 8 and 64 inclusive (this does not conform +to the OFB mode specification). +.TP +\-p +Disable the resetting of the parity bit. +This flag forces the parity bit of the key to be used as typed, rather than +making each character be of odd parity. +It is used only if the key is given in ASCII. +.TP +\-v +Set the initialization vector to +.IR vector ; +the vector is interpreted in the same way as the key. +The vector is ignored in electronic codebook mode. +.PP +The key and initialization vector are taken as sequences of ASCII +characters which are then mapped into their bit representations. +If either begins with ``0X'' or ``0x'', +that one is taken as a sequence of hexadecimal digits indicating the +bit pattern; +if either begins with ``0B'' or ``0b'', +that one is taken as a sequence of binary digits indicating the bit pattern. +In either case, +only the leading 64 bits of the key or initialization vector +are used, +and if fewer than 64 bits are provided, enough 0 bits are appended +to pad the key to 64 bits. +.PP +According to the DES standard, the low-order bit of each character in the +key string is deleted. +Since most ASCII representations set the high-order bit to 0, simply +deleting the low-order bit effectively reduces the size of the key space +from 2\u\s-356\s0\d to 2\u\s-348\s0\d keys. +To prevent this, the high-order bit must be a function depending in part +upon the low-order bit; so, the high-order bit is set to whatever value +gives odd parity. +This preserves the key space size. +Note this resetting of the parity bit is +.I not +done if the key is given in binary or hex, and can be disabled for ASCII +keys as well. +.PP +The DES is considered a very strong cryptosystem, and other than table lookup +attacks, key search attacks, and Hellman's time-memory tradeoff (all of which +are very expensive and time-consuming), no cryptanalytic methods for breaking +the DES are known in the open literature. +No doubt the choice of keys and key security are the most vulnerable aspect +of +.IR bdes . +.SH IMPLEMENTATION NOTES +For implementors wishing to write software compatible with this program, +the following notes are provided. +This software is believed to be compatible with the implementation of the +data encryption standard distributed by Sun Microsystems, Inc. +.PP +In the ECB and CBC modes, plaintext is encrypted in units of 64 bits (8 bytes, +also called a block). +To ensure that the plaintext file is encrypted correctly, +.I bdes +will (internally) append from 1 to 8 bytes, the last byte containing an +integer stating how many bytes of that final block are from the plaintext +file, and encrypt the resulting block. +Hence, when decrypting, the last block may contain from 0 to 7 characters +present in the plaintext file, and the last byte tells how many. +Note that if during decryption the last byte of the file does not contain an +integer between 0 and 7, either the file has been corrupted or an incorrect +key has been given. +A similar mechanism is used for the OFB and CFB modes, except that those +simply require the length of the input to be a multiple of the mode size, +and the final byte contains an integer between 0 and one less than the number +of bytes being used as the mode. +(This was another reason that the mode size must be a multiple of 8 for those +modes.) +.PP +Unlike Sun's implementation, unused bytes of that last block are not filled +with random data, but instead contain what was in those byte positions in +the preceding block. +This is quicker and more portable, and does not weaken the encryption +significantly. +.PP +If the key is entered in ASCII, the parity bits of the key characters are set +so that each key character is of odd parity. +Unlike Sun's implementation, it is possible to enter binary or hexadecimal +keys on the command line, and if this is done, the parity bits are +.I not +reset. +This allows testing using arbitrary bit patterns as keys. +.PP +The Sun implementation always uses an initialization vector of 0 +(that is, all zeroes). +By default, +.I bdes +does too, but this may be changed from the command line. +.SH SEE ALSO +crypt(1), crypt(3), getpass(3) +.sp +.IR "Data Encryption Standard" , +Federal Information Processing Standard #46, +National Bureau of Standards, +U.S. Department of Commerce, +Washington DC +(Jan. 1977) +.sp +.IR "DES Modes of Operation" , +Federal Information Processing Standard #81, +National Bureau of Standards, +U.S. Department of Commerce +Washington DC +(Dec. 1980) +.sp +Dorothy Denning, +.IR "Cryptography and Data Security" , +Addison-Wesley Publishing Co., +Reading, MA +\(co1982. +.sp +Matt Bishop, +.IR "Implementation Notes on bdes(1)" , +Technical Report PCS-TR-91-158, +Department of Mathematics and Computer Science, +Dartmouth College, +Hanover, NH 03755 +(Apr. 1991). +.SH DISCLAIMER +.nf +THIS SOFTWARE IS PROVIDED BY THE REGENTS AND CONTRIBUTORS ``AS IS'' AND +ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE +ARE DISCLAIMED.

The algorithm for calculating the day of week from any +Gregorian date was "reverse engineered". This was necessary as most of +the documented algorithms have to do with date calculations for other +calendars (e.g. julian) and are only accurate when converted to gregorian +within a narrow range of dates. + +1 Jan 1 is a Saturday because that's what cal says and I couldn't change +that even if I was dumb enough to try. From this we can easily calculate +the day of week for any date. The algorithm for a zero based day of week: + + calculate the number of days in all prior years (year-1)*365 + add the number of leap years (days?) since year 1 + (not including this year as that is covered later) + add the day number within the year + this compensates for the non-inclusive leap year + calculation + if the day in question occurs before the gregorian reformation + (3 sep 1752 for our purposes), then simply return + (value so far - 1 + SATURDAY's value of 6) modulo 7. + if the day in question occurs during the reformation (3 sep 1752 + to 13 sep 1752 inclusive) return THURSDAY. This is my + idea of what happened then. It does not matter much as + this program never tries to find day of week for any day + that is not the first of a month. + otherwise, after the reformation, use the same formula as the + days before with the additional step of subtracting the + number of days (11) that were adjusted out of the calendar + just before taking the modulo. + +It must be noted that the number of leap years calculation is sensitive +to the date for which the leap year is being calculated. A year that occurs +before the reformation is determined to be a leap year if its modulo of +4 equals zero. But after the reformation, a year is only a leap year if +its modulo of 4 equals zero and its modulo of 100 does not. Of course, +there is an exception for these century years. If the modulo of 400 equals +zero, then the year is a leap year anyway. This is, in fact, what the +gregorian reformation was all about (a bit of error in the old algorithm +that caused the calendar to be inaccurate.) + +Once we have the day in year for the first of the month in question, the +rest is trivial. diff --git a/usr.bin/cal/cal.1 b/usr.bin/cal/cal.1 new file mode 100644 index 0000000..80d95b2 --- /dev/null +++ b/usr.bin/cal/cal.1 @@ -0,0 +1,81 @@ +.\" Copyright (c) 1989, 1990, 1993 +.\" The Regents of the University of California.

A quiet "-q" flag has been added for use by the news system. + +3. The character chaining has been deleted and the program now uses + hashing.

(Beware: this option is implemented in a way which is rather +slow; it is usually faster to simply rebuild the +.Ar tags +file.) +.It Fl v +An index of the form expected by +.Xr vgrind 1 +is produced on the standard output. This listing +contains the object name, file name, and page number (assuming 64 +line pages). Since the output will be sorted into lexicographic order, +it may be desired to run the output through +.Xr sort 1 . +Sample use: +.Bd -literal -offset indent +ctags \-v files \&| sort \-f > index +vgrind \-x index +.Ed +.It Fl w +suppress warning diagnostics. +.It Fl x +.Nm ctags +produces a list of object +names, the line number and file name on which each is defined, as well +as the text of that line and prints this on the standard output. This +is a simple index which can be printed out as an off-line readable +function index. +.El +.Pp +Files whose names end in +.Nm \&.c +or +.Nm \&.h +are assumed to be C +source files and are searched for C style routine and macro definitions. +Files whose names end in +.Nm \&.y +are assumed to be +.Tn YACC +source files. +Files whose names end in +.Nm \&.l +are assumed to be lisp files if their +first non-blank character is `;', `(', or `[', +otherwise, they are +treated as lex files. Other files are first examined to see if they +contain any Pascal or Fortran routine definitions, and, if not, are +searched for C style definitions. +.Pp +The tag +.Li main +is treated specially in C programs. The tag formed +is created by prepending +.Ar M +to the name of the file, with the +trailing +.Nm \&.c +and any leading pathname components removed. This +makes use of +.Nm ctags +practical in directories with more than one +program. +.Pp +Yacc and lex files each have a special tag. +.Ar Yyparse +is the start +of the second section of the yacc file, and +.Ar yylex +is the start of +the second section of the lex file. +.Sh FILES +.Bl -tag -width tags -compact +.It Pa tags +default output tags file +.El +.Sh DIAGNOSTICS +.Nm Ctags +exits with a value of 1 if an error occurred, 0 otherwise. +Duplicate objects are not considered errors. +.Sh SEE ALSO +.Xr ex 1 , +.Xr vi 1 +.Sh BUGS +Recognition of +.Nm functions , +.Nm subroutines +and +.Nm procedures +for +.Tn FORTRAN +and Pascal is done is a very simpleminded way.

It also finds some legal syntax +confusing; for example, since it doesn't understand +.Li #ifdef Ns 's +(incidentally, that's a feature, not a bug), any code with unbalanced +braces inside +.Li #ifdef Ns 's +will cause it to become somewhat disoriented. +In a similar fashion, multiple line changes within a definition will +cause it to enter the last line of the object, rather than the first, as +the searching pattern.

File information of all symbolic links not on +the command line is that of the link itself. +.It Fl L +The +.Fl L +option causes the file information and file type (see +.Xr stat 2) +returned for each symbolic link to be those of the file referenced by the +link, not the link itself. +If the referenced file does not exist, the file information and type will +be for the link itself. +.It Fl P +The +.Fl P +option causes the file information and file type (see +.Xr stat 2) +returned for each symbolic link to be those of the link itself. +.It Fl X +The +.Fl X +option is a modification to permit +.Nm +to be safely used in conjunction with +.Xr xargs 1 . +If a file name contains any of the delimiting characters used by +.Xr xargs , +a diagnostic message is displayed on standard error, and the file +is skipped. +The delimiting characters include single (`` ' '') and double (`` " '') +quotes, backslash (``\e''), space, tab and newline characters. +.It Fl d +The +.Fl d +option causes +.Nm find +to perform a depth\-first traversal, i.e. directories +are visited in post\-order and all entries in a directory will be acted +on before the directory itself. +By default, +.Nm find +visits directories in pre\-order, i.e. before their contents. +Note, the default is +.Ar not +a breadth\-first traversal. +.It Fl f +The +.Fl f +option specifies a file hierarchy for +.Nm find +to traverse. +File hierarchies may also be specified as the operands immediately +following the options. +.It Fl x +The +.Fl x +option prevents +.Nm find +from descending into directories that have a device number different +than that of the file from which the descent began. +.El +.Sh PRIMARIES +.Bl -tag -width Ds +.It Ic -atime Ar n +True if the difference between the file last access time and the time +.Nm find +was started, rounded up to the next full 24\-hour period, is +.Ar n +24\-hour periods. +.It Ic -ctime Ar n +True if the difference between the time of last change of file status +information and the time +.Nm find +was started, rounded up to the next full 24\-hour period, is +.Ar n +24\-hour periods. +.It Ic -exec Ar utility Op argument ... ; +True if the program named +.Ar utility +returns a zero value as its exit status. +Optional arguments may be passed to the utility. +The expression must be terminated by a semicolon (``;''). +If the string ``{}'' appears anywhere in the utility name or the +arguments it is replaced by the pathname of the current file. +.Ar Utility +will be executed from the directory from which +.Nm find +was executed. +.It Ic -fstype Ar type +True if the file is contained in a file system of type +.Ar type . +Currently supported types are ``local'', ``mfs'', ``nfs'', ``msdos'', +``rdonly'' and ``ufs''. +The types ``local'' and ``rdonly'' are not specific file system types. +The former matches any file system physically mounted on the system where +the +.Nm find +is being executed and the latter matches any file system which is +mounted read-only. +.It Ic -group Ar gname +True if the file belongs to the group +.Ar gname . +If +.Ar gname +is numeric and there is no such group name, then +.Ar gname +is treated as a group id. +.It Ic -inum Ar n +True if the file has inode number +.Ar n . +.It Ic -links Ar n +True if the file has +.Ar n +links. +.It Ic -ls +This primary always evaluates to true. +The following information for the current file is written to standard output: +its inode number, size in 512\-byte blocks, file permissions, number of hard +links, owner, group, size in bytes, last modification time, and pathname. +If the file is a block or character special file, the major and minor numbers +will be displayed instead of the size in bytes. +If the file is a symbolic link, the pathname of the linked\-to file will be +displayed preceded by ``\->''. +The format is identical to that produced by ``ls \-dgils''. +.It Ic -mtime Ar n +True if the difference between the file last modification time and the time +.Nm find +was started, rounded up to the next full 24\-hour period, is +.Ar n +24\-hour periods. +.It Ic \&-ok Ar utility Ns Op argument ... ; +The +.Ic \&-ok +primary is identical to the +.Ic -exec +primary with the exception that +.Nm find +requests user affirmation for the execution of the utility by printing +a message to the terminal and reading a response. +If the response is other than ``y'' the command is not executed and the +value of the +.Ar \&ok +expression is false. +.It Ic -name Ar pattern +True if the last component of the pathname being examined matches +.Ar pattern . +Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'') +may be used as part of +.Ar pattern . +These characters may be matched explicitly by escaping them with a +backslash (``\e''). +.It Ic -newer Ar file +True if the current file has a more recent last modification time than +.Ar file . +.It Ic -nouser +True if the file belongs to an unknown user. +.It Ic -nogroup +True if the file belongs to an unknown group. +.It Ic -path Ar pattern +True if the pathname being examined matches +.Ar pattern . +Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'') +may be used as part of +.Ar pattern . +These characters may be matched explicitly by escaping them with a +backslash (``\e''). +Slashes (``/'') are treated as normal characters and do not have to be +matched explicitly. +.It Ic -perm Op Fl Ns Ar mode +The +.Ar mode +may be either symbolic (see +.Xr chmod 1 ) +or an octal number. +If the mode is symbolic, a starting value of zero is assumed and the +mode sets or clears permissions without regard to the process' file mode +creation mask. +If the mode is octal, only bits 07777 +.Pf ( Dv S_ISUID +| +.Dv S_ISGID +| +.Dv S_ISTXT +| +.Dv S_IRWXU +| +.Dv S_IRWXG +| +.Dv S_IRWXO ) +of the file's mode bits participate +in the comparison. +If the mode is preceded by a dash (``\-''), this primary evaluates to true +if at least all of the bits in the mode are set in the file's mode bits. +If the mode is not preceded by a dash, this primary evaluates to true if +the bits in the mode exactly match the file's mode bits. +Note, the first character of a symbolic mode may not be a dash (``\-''). +.It Ic -print +This primary always evaluates to true. +It prints the pathname of the current file to standard output. +The expression is appended to the user specified expression if neither +.Ic -exec , +.Ic -ls +or +.Ic \&-ok +is specified. +.It Ic -prune +This primary always evaluates to true. +It causes +.Nm find +to not descend into the current file. +Note, the +.Ic -prune +primary has no effect if the +.Fl d +option was specified. +.It Ic -size Ar n Ns Op Cm c +True if the file's size, rounded up, in 512\-byte blocks is +.Ar n . +If +.Ar n +is followed by a ``c'', then the primary is true if the +file's size is +.Ar n +bytes. +.It Ic -type Ar t +True if the file is of the specified type. +Possible file types are as follows: +.Pp +.Bl -tag -width flag -offset indent -compact +.It Cm b +block special +.It Cm c +character special +.It Cm d +directory +.It Cm f +regular file +.It Cm l +symbolic link +.It Cm p +FIFO +.It Cm s +socket +.El +.Pp +.It Ic -user Ar uname +True if the file belongs to the user +.Ar uname . +If +.Ar uname +is numeric and there is no such user name, then +.Ar uname +is treated as a user id. +.El +.Pp +All primaries which take a numeric argument allow the number to be +preceded by a plus sign (``+'') or a minus sign (``\-''). +A preceding plus sign means ``more than n'', a preceding minus sign means +``less than n'' and neither means ``exactly n'' . +.Sh OPERATORS +The primaries may be combined using the following operators. +The operators are listed in order of decreasing precedence. +.Bl -tag -width (expression) +.It Cm \&( Ns Ar expression Ns Cm \&) +This evaluates to true if the parenthesized expression evaluates to +true. +.Pp +.It Cm \&!

Print the device number (maj,min) of the filesystem +the file resides in rather than the mount point name; for special +files, print the +device number that the special device refers to rather than the filename +in +.Pa /dev ; +and print the mode of the file in octal instead of symbolic form. +.It Fl p +Report all files open by the specified process. +.It Fl u +Report all files open by the specified user. +.It Fl v +Verbose mode. Print error messages upon failures to locate particular +system data structures rather than silently ignoring them. Most of +these data structures are dynamically created or deleted and it is +possible for them to disappear while +.Nm fstat +is running. This +is normal and unavoidable since the rest of the system is running while +.Nm fstat +itself is running. +.It Ar filename ... +Restrict reports to the specified files. +.El +.Pp +The following fields are printed: +.Bl -tag -width MOUNT +.It Li USER +The username of the owner of the process (effective uid). +.It Li CMD +The command name of the process. +.It Li PID +The process id. +.It Li FD +The file number in the per-process open file table or one of the following +special names: +.Pp +.Bd -ragged -offset indent -compact +text - pure text inode +wd - current working directory +root - root inode +tr - kernel trace file +.Ed +.Pp +If the file number is followed by an asterisk (``*''), the file is +not an inode, but rather a socket, +.Tn FIFO , +or there is an error. +In this case the remainder of the line doesn't +correspond to the remaining headers -- the format of the line +is described later under +.Sx Sockets . +.It Li MOUNT +If the +.Fl n +flag wasn't specified, this header is present and is the +pathname that the filesystem the file resides in is mounted on. +.It Li DEV +If the +.Fl n +flag is specified, this header is present and is the +major/minor number of the device that this file resides in. +.It Li INUM +The inode number of the file. +.It Li MODE +The mode of the file. If the +.Fl n +flag isn't specified, the mode is printed +using a symbolic format (see +.Xr strmode 3 ) ; +otherwise, the mode is printed +as an octal number. +.It Li SZ\&|DV +If the file is not a character or block special, prints the size of +the file in bytes. Otherwise, if the +.Fl n +flag is not specified, prints +the name of the special file as located in +.Pa /dev . +If that cannot be +located, or the +.Fl n +flag is specified, prints the major/minor device +number that the special device refers to. +.It Li R/W +This column describes the access mode that the file allows. +The letter ``r'' indicates open for reading; +the letter ``w'' indicates open for writing. +This field is useful when trying to find the processes that are +preventing a filesystem from being down graded to read-only. +.It Li NAME +If filename arguments are specified and the +.Fl f +flag is not, then +this field is present and is the name associated with the given file. +Normally the name cannot be determined since there is no mapping +from an open file back to the directory entry that was used to open +that file. Also, since different directory entries may reference +the same file (via +.Xr ln 2 ) , +the name printed may not be the actual +name that the process originally used to open that file. +.El +.Sh SOCKETS +The formating of open sockets depends on the protocol domain. +In all cases the first field is the domain name, the second field +is the socket type (stream, dgram, etc), and the third is the socket +flags field (in hex). +The remaining fields are protocol dependent. +For tcp, it is the address of the tcpcb, and for udp, the inpcb (socket pcb). +For unix domain sockets, its the address of the socket pcb and the address +of the connected pcb (if connected). +Otherwise the protocol number and address of the socket itself are printed. +The attempt is to make enough information available to +permit further analysis without duplicating +.Xr netstat 1 . +.Pp +For example, the addresses mentioned above are the addresses which the +.Dq Li netstat -A +command would print for tcp, udp, and unixdomain. +Note that since pipes are implemented using sockets, a pipe appears as a +connected unix domain stream socket. +A unidirectional unix domain socket indicates the direction of flow with +an arrow (``<-'' or ``->''), and a full duplex socket shows a double arrow +(``<->''). +.Sh BUGS +Since +.Nm fstat +takes a snapshot of the system, it is only correct for a very short period +of time. +.Sh SEE ALSO +.Xr netstat 1 , +.Xr nfsstat 1 , +.Xr ps 1 , +.Xr systat 1 , +.Xr vmstat 1 , +.Xr iostat 8 , +.Xr pstat 8 +.Sh HISTORY +The +.Nm +command appeared in +.Bx 4.3 tahoe . diff --git a/usr.bin/fstat/fstat.c b/usr.bin/fstat/fstat.c new file mode 100644 index 0000000..90d7304 --- /dev/null +++ b/usr.bin/fstat/fstat.c @@ -0,0 +1,746 @@ +/*- + * Copyright (c) 1988, 1993 + * The Regents of the University of California.

Op Ar command Op Ar args +Invoke an interactive shell on the local machine. +If there are arguments, the first is taken to be a command to execute +directly, with the rest of the arguments as its arguments. +.It Ic \&$ Ar macro-name Op Ar args +Execute the macro +.Ar macro-name +that was defined with the +.Ic macdef +command. +Arguments are passed to the macro unglobbed. +.It Ic account Op Ar passwd +Supply a supplemental password required by a remote system for access +to resources once a login has been successfully completed. +If no argument is included, the user will be prompted for an account +password in a non-echoing input mode. +.It Ic append Ar local-file Op Ar remote-file +Append a local file to a file on the remote machine. +If +.Ar remote-file +is left unspecified, the local file name is used in naming the +remote file after being altered by any +.Ic ntrans +or +.Ic nmap +setting. +File transfer uses the current settings for +.Ic type , +.Ic format , +.Ic mode , +and +.Ic structure . +.It Ic ascii +Set the file transfer +.Ic type +to network +.Tn ASCII . +This is the default type. +.It Ic bell +Arrange that a bell be sounded after each file transfer +command is completed. +.It Ic binary +Set the file transfer +.Ic type +to support binary image transfer. +.It Ic bye +Terminate the +.Tn FTP +session with the remote server +and exit +.Nm ftp . +An end of file will also terminate the session and exit. +.It Ic case +Toggle remote computer file name case mapping during +.Ic mget +commands. +When +.Ic case +is on (default is off), remote computer file names with all letters in +upper case are written in the local directory with the letters mapped +to lower case. +.It Ic \&cd Ar remote-directory +Change the working directory on the remote machine +to +.Ar remote-directory . +.It Ic cdup +Change the remote machine working directory to the parent of the +current remote machine working directory. +.It Ic chmod Ar mode file-name +Change the permission modes of the file +.Ar file-name +on the remote +sytem to +.Ar mode . +.It Ic close +Terminate the +.Tn FTP +session with the remote server, and +return to the command interpreter. +Any defined macros are erased. +.It Ic \&cr +Toggle carriage return stripping during +ascii type file retrieval. +Records are denoted by a carriage return/linefeed sequence +during ascii type file transfer. +When +.Ic \&cr +is on (the default), carriage returns are stripped from this +sequence to conform with the +.Ux +single linefeed record +delimiter. +Records on +.Pf non\- Ns Ux +remote systems may contain single linefeeds; +when an ascii type transfer is made, these linefeeds may be +distinguished from a record delimiter only when +.Ic \&cr +is off. +.It Ic delete Ar remote-file +Delete the file +.Ar remote-file +on the remote machine. +.It Ic debug Op Ar debug-value +Toggle debugging mode. +If an optional +.Ar debug-value +is specified it is used to set the debugging level. +When debugging is on, +.Nm ftp +prints each command sent to the remote machine, preceded +by the string +.Ql \-\-> +.It Xo +.Ic dir +.Op Ar remote-directory +.Op Ar local-file +.Xc +Print a listing of the directory contents in the +directory, +.Ar remote-directory , +and, optionally, placing the output in +.Ar local-file . +If interactive prompting is on, +.Nm ftp +will prompt the user to verify that the last argument is indeed the +target local file for receiving +.Ic dir +output. +If no directory is specified, the current working +directory on the remote machine is used. +If no local +file is specified, or +.Ar local-file +is +.Fl , +output comes to the terminal. +.It Ic disconnect +A synonym for +.Ar close . +.It Ic form Ar format +Set the file transfer +.Ic form +to +.Ar format . +The default format is \*(Lqfile\*(Rq. +.It Ic get Ar remote-file Op Ar local-file +Retrieve the +.Ar remote-file +and store it on the local machine. +If the local +file name is not specified, it is given the same

structure +are used while transferring the file. +.It Ic glob +Toggle filename expansion for +.Ic mdelete , +.Ic mget +and +.Ic mput . +If globbing is turned off with +.Ic glob , +the file name arguments +are taken literally and not expanded. +Globbing for +.Ic mput +is done as in +.Xr csh 1 . +For +.Ic mdelete +and +.Ic mget , +each remote file name is expanded +separately on the remote machine and the lists are not merged. +Expansion of a directory name is likely to be +different from expansion of the name of an ordinary file: +the exact result depends on the foreign operating system and ftp server, +and can be previewed by doing +.Ql mls remote-files \- +Note: +.Ic mget +and +.Ic mput +are not meant to transfer +entire directory subtrees of files. +That can be done by +transferring a +.Xr tar 1 +archive of the subtree (in binary mode). +.It Ic hash +Toggle hash-sign (``#'') printing for each data block +transferred. +The size of a data block is 1024 bytes. +.It Ic help Op Ar command +Print an informative message about the meaning of +.Ar command . +If no argument is given, +.Nm ftp +prints a list of the known commands. +.It Ic idle Op Ar seconds +Set the

ls \-l . +(See also +.Ic nlist . ) +If +.Ar remote-directory +is left unspecified, the current working directory is used. +If interactive prompting is on, +.Nm ftp +will prompt the user to verify that the last argument is indeed the +target local file for receiving +.Ic \&ls +output. +If no local file is specified, or if +.Ar local-file +is +.Sq Fl , +the output is sent to the terminal. +.It Ic macdefNs Ar macro-name +Define a macro. +Subsequent lines are stored as the macro +.Ar macro-name ; +a null line (consecutive newline characters +in a file or +carriage returns from the terminal) terminates macro input mode. +There is a limit of 16 macros and 4096 total characters in all +defined macros. +Macros remain defined until a +.Ic close +command is executed. +The macro processor interprets `$' and `\e' as special characters. +A `$' followed by a number (or numbers) is replaced by the +corresponding argument on the macro invocation command line. +A `$' followed by an `i' signals that macro processor that the +executing macro is to be looped. +On the first pass `$i' is +replaced by the first argument on the macro invocation command line, +on the second pass it is replaced by the second argument, and so on. +A `\e' followed by any character is replaced by that character. +Use the `\e' to prevent special treatment of the `$'. +.It Ic mdelete Op Ar remote-files +Delete the +.Ar remote-files +on the remote machine. +.It Ic mdir Ar remote-files local-file +Like +.Ic dir , +except multiple remote files may be specified. +If interactive prompting is on, +.Nm ftp +will prompt the user to verify that the last argument is indeed the +target local file for receiving +.Ic mdir +output. +.It Ic mget Ar remote-files +Expand the +.Ar remote-files +on the remote machine +and do a +.Ic get +for each file name thus produced. +See +.Ic glob +for details on the filename expansion. +Resulting file names will then be processed according to +.Ic case , +.Ic ntrans , +and +.Ic nmap +settings. +Files are transferred into the local working directory, +which can be changed with +.Ql lcd directory ; +new local directories can be created with +.Ql "\&! mkdir directory" . +.It Ic mkdir Ar directory-name +Make a directory on the remote machine. +.It Ic mls Ar remote-files local-file +Like +.Ic nlist , +except multiple remote files may be specified, +and the +.Ar local-file +must be specified. +If interactive prompting is on, +.Nm ftp +will prompt the user to verify that the last argument is indeed the +target local file for receiving +.Ic mls +output. +.It Ic mode Op Ar mode-name +Set the file transfer +.Ic mode +to +.Ar mode-name . +The default mode is \*(Lqstream\*(Rq mode. +.It Ic modtime Ar file-name +Show the last modification time of the file on the remote machine. +.It Ic mput Ar local-files +Expand wild cards in the list of local files given as arguments +and do a +.Ic put +for each file in the resulting list. +See +.Ic glob +for details of filename expansion. +Resulting file names will then be processed according to +.Ic ntrans +and +.Ic nmap +settings. +.It Ic newer Ar file-name +Get the file only if the modification time of the remote file is more +recent that the file on the current system. +If the file does not +exist on the current system, the remote file is considered +.Ic newer . +Otherwise, this command is identical to +.Ar get . +.It Xo +.Ic nlist +.Op Ar remote-directory +.Op Ar local-file +.Xc +Print a list of the files in a +directory on the remote machine. +If +.Ar remote-directory +is left unspecified, the current working directory is used. +If interactive prompting is on, +.Nm ftp +will prompt the user to verify that the last argument is indeed the +target local file for receiving +.Ic nlist +output. +If no local file is specified, or if +.Ar local-file +is +.Fl , +the output is sent to the terminal. +.It Ic nmap Op Ar inpattern outpattern +Set or unset the filename mapping mechanism. +If no arguments are specified, the filename mapping mechanism is unset. +If arguments are specified, remote filenames are mapped during +.Ic mput +commands and +.Ic put +commands issued without a specified remote target filename. +If arguments are specified, local filenames are mapped during +.Ic mget +commands and +.Ic get +commands issued without a specified local target filename. +This command is useful when connecting to a +.No non\- Ns Ux +remote computer +with different file naming conventions or practices. +The mapping follows the pattern set by +.Ar inpattern +and +.Ar outpattern . +.Op Ar Inpattern +is a template for incoming filenames (which may have already been +processed according to the +.Ic ntrans +and +.Ic case +settings). +Variable templating is accomplished by including the +sequences `$1', `$2', ..., `$9' in +.Ar inpattern . +Use `\\' to prevent this special treatment of the `$' character. +All other characters are treated literally, and are used to determine the +.Ic nmap +.Op Ar inpattern +variable values. +For example, given +.Ar inpattern +$1.$2 and the remote file name "mydata.data", $1 would have the value +"mydata", and $2 would have the value "data". +The +.Ar outpattern +determines the resulting mapped filename. +The sequences `$1', `$2', ...., `$9' are replaced by any value resulting +from the +.Ar inpattern +template. +The sequence `$0' is replace by the original filename. +Additionally, the sequence +.Ql Op Ar seq1 , Ar seq2 +is replaced by +.Op Ar seq1 +if +.Ar seq1 +is not a null string; otherwise it is replaced by +.Ar seq2 . +For example, the command +.Pp +.Bd -literal -offset indent -compact +nmap $1.$2.$3 [$1,$2].[$2,file] +.Ed +.Pp +would yield +the output filename "myfile.data" for input filenames "myfile.data" and +"myfile.data.old", "myfile.file" for the input filename "myfile", and +"myfile.myfile" for the input filename ".myfile". +Spaces may be included in +.Ar outpattern , +as in the example: `nmap $1 sed "s/ *$//" > $1' . +Use the `\e' character to prevent special treatment +of the `$','[','[', and `,' characters. +.It Ic ntrans Op Ar inchars Op Ar outchars +Set or unset the filename character translation mechanism. +If no arguments are specified, the filename character +translation mechanism is unset. +If arguments are specified, characters in +remote filenames are translated during +.Ic mput +commands and +.Ic put +commands issued without a specified remote target filename. +If arguments are specified, characters in +local filenames are translated during +.Ic mget +commands and +.Ic get +commands issued without a specified local target filename. +This command is useful when connecting to a +.No non\- Ns Ux +remote computer +with different file naming conventions or practices. +Characters in a filename matching a character in +.Ar inchars +are replaced with the corresponding character in +.Ar outchars . +If the character's position in +.Ar inchars +is longer than the length of +.Ar outchars , +the character is deleted from the file name. +.It Ic open Ar host Op Ar port +Establish a connection to the specified +.Ar host +.Tn FTP +server. +An optional port number may be supplied, +in which case, +.Nm ftp +will attempt to contact an +.Tn FTP +server at that port. +If the +.Ic auto-login +option is on (default), +.Nm ftp +will also attempt to automatically log the user in to +the +.Tn FTP +server (see below). +.It Ic prompt +Toggle interactive prompting. +Interactive prompting +occurs during multiple file transfers to allow the +user to selectively retrieve or store files. +If prompting is turned off (default is on), any +.Ic mget +or +.Ic mput +will transfer all files, and any +.Ic mdelete +will delete all files. +.It Ic proxy Ar ftp-command +Execute an ftp command on a secondary control connection. +This command allows simultaneous connection to two remote ftp +servers for transferring files between the two servers. +The first +.Ic proxy +command should be an +.Ic open , +to establish the secondary control connection. +Enter the command "proxy ?" to see other ftp commands executable on the +secondary connection. +The following commands behave differently when prefaced by +.Ic proxy : +.Ic open +will not define new macros during the auto-login process, +.Ic close +will not erase existing macro definitions, +.Ic get +and +.Ic mget +transfer files from the host on the primary control connection +to the host on the secondary control connection, and +.Ic put , +.Ic mput , +and +.Ic append +transfer files from the host on the secondary control connection +to the host on the primary control connection. +Third party file transfers depend upon support of the ftp protocol +.Dv PASV +command by the server on the secondary control connection. +.It Ic put Ar local-file Op Ar remote-file +Store a local file on the remote machine. +If +.Ar remote-file +is left unspecified, the local file name is used +after processing according to any +.Ic ntrans +or +.Ic nmap +settings +in naming the remote file. +File transfer uses the +current settings for +.Ic type , +.Ic format , +.Ic mode , +and +.Ic structure . +.It Ic pwd +Print the name of the current working directory on the remote +machine. +.It Ic quit +A synonym for +.Ic bye . +.It Ic quote Ar arg1 arg2 ... +The arguments specified are sent, verbatim, to the remote +.Tn FTP +server. +.It Ic recv Ar remote-file Op Ar local-file +A synonym for get. +.It Ic reget Ar remote-file Op Ar local-file +Reget acts like get, except that if +.Ar local-file +exists and is +smaller than +.Ar remote-file , +.Ar local-file +is presumed to be +a partially transferred copy of +.Ar remote-file +and the transfer +is continued from the apparent point of failure. +This command +is useful when transferring very large files over networks that +are prone to dropping connections. +.It Ic remotehelp Op Ar command-name +Request help from the remote +.Tn FTP +server. +If a +.Ar command-name +is specified it is supplied to the server as well. +.It Ic remotestatus Op Ar file-name +With no arguments, show status of remote machine. +If +.Ar file-name +is specified, show status of +.Ar file-name +on remote machine. +.It Xo +.Ic rename +.Op Ar from +.Op Ar to +.Xc +Rename the file +.Ar from +on the remote machine, to the file +.Ar to . +.It Ic reset +Clear reply queue. +This command re-synchronizes command/reply sequencing with the remote +ftp server. +Resynchronization may be necessary following a violation of the ftp protocol +by the remote server. +.It Ic restart Ar marker +Restart the immediately following +.Ic get +or +.Ic put +at the +indicated +.Ar marker . +On +.Ux +systems, marker is usually a byte +offset into the file. +.It Ic rmdir Ar directory-name +Delete a directory on the remote machine. +.It Ic runique +Toggle storing of files on the local system with unique filenames. +If a file already exists with a name equal to the target +local filename for a +.Ic get +or +.Ic mget +command, a ".1" is appended to the name. +If the resulting name matches another existing file, +a ".2" is appended to the original name. +If this process continues up to ".99", an error +message is printed, and the transfer does not take place. +The generated unique filename will be reported. +Note that +.Ic runique +will not affect local files generated from a shell command +(see below). +The default value is off. +.It Ic send Ar local-file Op Ar remote-file +A synonym for put. +.It Ic sendport +Toggle the use of +.Dv PORT +commands. +By default, +.Nm ftp +will attempt to use a +.Dv PORT +command when establishing +a connection for each data transfer. +The use of +.Dv PORT +commands can prevent delays +when performing multiple file transfers. +If the +.Dv PORT +command fails, +.Nm ftp +will use the default data port. +When the use of +.Dv PORT +commands is disabled, no attempt will be made to use +.Dv PORT +commands for each data transfer. +This is useful +for certain +.Tn FTP +implementations which do ignore +.Dv PORT +commands but, incorrectly, indicate they've been accepted. +.It Ic site Ar arg1 arg2 ... +The arguments specified are sent, verbatim, to the remote +.Tn FTP +server as a +.Dv SITE +command. +.It Ic size Ar file-name +Return size of +.Ar file-name +on remote machine. +.It Ic status +Show the current status of +.Nm ftp . +.It Ic struct Op Ar struct-name +Set the file transfer +.Ar structure +to +.Ar struct-name . +By default \*(Lqstream\*(Rq structure is used. +.It Ic sunique +Toggle storing of files on remote machine under unique file names. +Remote ftp server must support ftp protocol +.Dv STOU +command for +successful completion. +The remote server will report unique name. +Default value is off. +.It Ic system +Show the type of operating system running on the remote machine. +.It Ic tenex +Set the file transfer type to that needed to +talk to +.Tn TENEX +machines. +.It Ic trace +Toggle packet tracing. +.It Ic type Op Ar type-name +Set the file transfer +.Ic type +to +.Ar type-name . +If no type is specified, the current type +is printed. +The default type is network +.Tn ASCII . +.It Ic umask Op Ar newmask +Set the default umask on the remote server to +.Ar newmask . +If +.Ar newmask +is omitted, the current umask is printed. +.It Xo +.Ic user Ar user-name +.Op Ar password +.Op Ar account +.Xc +Identify yourself to the remote +.Tn FTP +server. +If the +.Ar password +is not specified and the server requires it, +.Nm ftp +will prompt the user for it (after disabling local echo). +If an +.Ar account +field is not specified, and the +.Tn FTP +server +requires it, the user will be prompted for it. +If an +.Ar account +field is specified, an account command will +be relayed to the remote server after the login sequence +is completed if the remote server did not require it +for logging in. +Unless +.Nm ftp +is invoked with \*(Lqauto-login\*(Rq disabled, this +process is done automatically on initial connection to +the +.Tn FTP +server. +.It Ic verbose +Toggle verbose mode. +In verbose mode, all responses from +the +.Tn FTP +server are displayed to the user. +In addition, +if verbose is on, when a file transfer completes, statistics +regarding the efficiency of the transfer are reported. +By default, +verbose is on. +.It Ic ? Op Ar command +A synonym for help. +.El +.Pp +Command arguments which have embedded spaces may be quoted with +quote `"' marks. +.Sh ABORTING A FILE TRANSFER +To abort a file transfer, use the terminal interrupt key +(usually Ctrl-C). +Sending transfers will be immediately halted. +Receiving transfers will be halted by sending a ftp protocol +.Dv ABOR +command to the remote server, and discarding any further data received. +The speed at which this is accomplished depends upon the remote +server's support for +.Dv ABOR +processing. +If the remote server does not support the +.Dv ABOR +command, an +.Ql ftp> +prompt will not appear until the remote server has completed +sending the requested file. +.Pp +The terminal interrupt key sequence will be ignored when +.Nm ftp +has completed any local processing and is awaiting a reply +from the remote server. +A long delay in this mode may result from the ABOR processing described +above, or from unexpected behavior by the remote server, including +violations of the ftp protocol. +If the delay results from unexpected remote server behavior, the local +.Nm ftp +program must be killed by hand. +.Sh FILE NAMING CONVENTIONS +Files specified as arguments to +.Nm ftp +commands are processed according to the following rules. +.Bl -enum +.It +If the file name +.Sq Fl +is specified, the +.Ar stdin +(for reading) or +.Ar stdout +(for writing) is used. +.It +If the first character of the file name is +.Sq \&| , +the +remainder of the argument is interpreted as a shell command. +.Nm Ftp +then forks a shell, using +.Xr popen 3 +with the argument supplied, and reads (writes) from the stdout +(stdin). +If the shell command includes spaces, the argument +must be quoted; e.g. +\*(Lq" ls -lt"\*(Rq. +A particularly +useful example of this mechanism is: \*(Lqdir more\*(Rq. +.It +Failing the above checks, if ``globbing'' is enabled, +local file names are expanded +according to the rules used in the +.Xr csh 1 ; +c.f. the +.Ic glob +command. +If the +.Nm ftp +command expects a single local file (.e.g. +.Ic put ) , +only the first filename generated by the "globbing" operation is used. +.It +For +.Ic mget +commands and +.Ic get +commands with unspecified local file names, the local filename is +the remote filename, which may be altered by a +.Ic case , +.Ic ntrans , +or +.Ic nmap +setting. +The resulting filename may then be altered if +.Ic runique +is on. +.It +For +.Ic mput +commands and +.Ic put +commands with unspecified remote file names, the remote filename is +the local filename, which may be altered by a +.Ic ntrans +or +.Ic nmap +setting. +The resulting filename may then be altered by the remote server if +.Ic sunique +is on. +.El +.Sh FILE TRANSFER PARAMETERS +The FTP specification specifies many parameters which may +affect a file transfer. +The +.Ic type +may be one of \*(Lqascii\*(Rq, \*(Lqimage\*(Rq (binary), +\*(Lqebcdic\*(Rq, and \*(Lqlocal byte size\*(Rq (for +.Tn PDP Ns -10's +and +.Tn PDP Ns -20's +mostly). +.Nm Ftp +supports the ascii and image types of file transfer, +plus local byte size 8 for +.Ic tenex +mode transfers. +.Pp +.Nm Ftp +supports only the default values for the remaining +file transfer parameters: +.Ic mode , +.Ic form , +and +.Ic struct . +.Sh THE .netrc FILE +The +.Pa .netrc +file contains login and initialization information +used by the auto-login process. +It resides in the user's home directory. +The following tokens are recognized; they may be separated by spaces, +tabs, or new-lines: +.Bl -tag -width password +.It Ic machine Ar name +Identify a remote machine +.Ar name . +The auto-login process searches the +.Pa .netrc +file for a +.Ic machine +token that matches the remote machine specified on the +.Nm ftp +command line or as an +.Ic open +command argument. +Once a match is made, the subsequent +.Pa .netrc +tokens are processed, +stopping when the end of file is reached or another +.Ic machine +or a +.Ic default +token is encountered. +.It Ic default +This is the same as +.Ic machine +.Ar name +except that +.Ic default +matches any name. +There can be only one +.Ic default +token, and it must be after all +.Ic machine +tokens. +This is normally used as: +.Pp +.Dl default login anonymous password user@site +.Pp +thereby giving the user +.Ar automatic +anonymous ftp login to +machines not specified in +.Pa .netrc . +This can be overridden +by using the +.Fl n +flag to disable auto-login. +.It Ic login Ar name +Identify a user on the remote machine. +If this token is present, the auto-login process will initiate +a login using the specified +.Ar name . +.It Ic password Ar string +Supply a password. +If this token is present, the auto-login process will supply the +specified string if the remote server requires a password as part +of the login process. +Note that if this token is present in the +.Pa .netrc +file for any user other +than +.Ar anonymous , +.Nm ftp +will abort the auto-login process if the +.Pa .netrc +is readable by +anyone besides the user. +.It Ic account Ar string +Supply an additional account password. +If this token is present, the auto-login process will supply the +specified string if the remote server requires an additional +account password, or the auto-login process will initiate an +.Dv ACCT +command if it does not. +.It Ic macdef Ar name +Define a macro. +This token functions like the +.Nm ftp +.Ic macdef +command functions. +A macro is defined with the specified name; its contents begin with the +next +.Pa .netrc +line and continue until a null line (consecutive new-line +characters) is encountered. +If a macro named +.Ic init +is defined, it is automatically executed as the last step in the +auto-login process. +.El +.Sh ENVIRONMENT +.Nm Ftp +utilizes the following environment variables. +.Bl -tag -width Fl +.It Ev HOME +For default location of a +.Pa .netrc +file, if one exists. +.It Ev SHELL +For default shell. +.El +.Sh SEE ALSO +.Xr ftpd 8 +.Sh HISTORY +The +.Nm ftp +command appeared in +.Bx 4.2 . +.Sh BUGS +Correct execution of many commands depends upon proper behavior +by the remote server. +.Pp +An error in the treatment of carriage returns +in the +.Bx 4.2 +ascii-mode transfer code +has been corrected. +This correction may result in incorrect transfers of binary files +to and from +.Bx 4.2 +servers using the ascii type. +Avoid this problem by using the binary image type. diff --git a/usr.bin/ftp/ftp.c b/usr.bin/ftp/ftp.c new file mode 100644 index 0000000..19e8f8e --- /dev/null +++ b/usr.bin/ftp/ftp.c @@ -0,0 +1,1470 @@ +/* + * Copyright (c) 1985, 1989, 1993, 1994 + * The Regents of the University of California.

+.\" +.sh 1 "Gathering Profile Data" +.pp +Routine calls or statement executions can be measured by having a +compiler augment the code at strategic points. +The additions can be inline increments to counters [Knuth71] +[Satterthwaite72] [Joy79] or calls to +monitoring routines [Unix]. +The counter increment overhead is low, and is suitable for +profiling statements. +A call of the monitoring routine has an overhead comparable with a +call of a regular routine, and is therefore only suited +to profiling on a routine by routine basis. +However, the monitoring routine solution has certain advantages. +Whatever counters are needed by the monitoring routine can be +managed by the monitoring routine itself, rather than being +distributed around the code. +In particular, a monitoring routine can easily be called from separately +compiled programs. +In addition, different monitoring routines can be linked into the +program +being measured +to assemble different profiling data without having to +change the compiler or recompile the program. +We have exploited this approach; +our compilers for C, Fortran77, and Pascal can insert calls to a +monitoring routine in the prologue for each routine. +Use of the monitoring routine requires no planning on part of a +programmer other than to request that augmented routine +prologues be produced during compilation. +.pp +We are interested in gathering three pieces of information during +program execution: call counts and execution times for +each profiled routine, and the arcs of the dynamic call graph +traversed by this execution of the program. +By post-processing of this data we can build the dynamic call +graph for this execution of the program and propagate times along +the edges of this graph to attribute times for routines to the +routines that invoke them. +.pp +Gathering of the profiling information should not greatly +interfere with the running of the program. +Thus, the monitoring routine must not produce trace output each +time it is invoked. +The volume of data thus produced would be unmanageably large, +and the time required to record it would overwhelm the running +time of most programs. +Similarly, the monitoring routine can not do the analysis of +the profiling data (e.g. assembling the call graph, propagating +times around it, discovering cycles, etc.) during program +execution. +Our solution is to gather profiling data in memory during program +execution and to condense it to a file as the profiled +program exits. +This file is then processed by a separate program to produce the +listing of the profile data. +An advantage of this approach is that the profile data for +several executions of a program can be combined by the +post-processing to provide a profile of many +executions. +.pp +The execution time monitoring consists of three parts. +The first part allocates and initializes the runtime monitoring data +structures before the program begins execution. +The second part is the monitoring routine invoked from the +prologue of each profiled routine. +The third part condenses the data structures and writes them +to a file as the program terminates. +The monitoring routine is discussed in detail in the following sections. +.sh 2 "Execution Counts" +.pp +The \fBgprof\fP monitoring routine counts the number of times +each profiled routine is called. +The monitoring routine also records the arc in the call graph +that activated the profiled routine. +The count is associated with the arc in the call graph +rather than with the routine. +Call counts for routines can then be determined by summing the counts +on arcs directed into that routine. +In a machine-dependent fashion, the monitoring routine notes its +own return address. +This address is in the prologue of some profiled routine that is +the destination of an arc in the dynamic call graph. +The monitoring routine also discovers the return address for that +routine, thus identifying the call site, or source of the arc. +The source of the arc is in the \fIcaller\fP, and the destination is in +the \fIcallee\fP. +For example, if a routine A calls a routine B, A is the caller, +and B is the callee. +The prologue of B will include a call to the monitoring routine +that will note the arc from A to B and either initialize or +increment a counter for that arc. +.pp +One can not afford to have the monitoring routine output tracing +information as each arc is identified. +Therefore, the monitoring routine maintains a table of all the +arcs discovered, with counts of the numbers of times each is +traversed during execution. +This table is accessed once per routine call. +Access to it +must be as fast as possible so as not to overwhelm the time +required to execute the program. +.pp +Our solution is to access the table through a hash table. +We use the call site as the primary key with the callee +address being the secondary key. +Since each call site typically calls only one callee, we can +reduce (usually to one) the number of minor lookups based on the callee. +Another alternative would use the callee as the primary key and the +call site as the secondary key. +Such an organization has the advantage of associating callers with +callees, at the expense of longer lookups in the monitoring +routine. +We are fortunate to be running in a virtual memory environment, +and (for the sake of speed) were able to allocate enough space +for the primary hash table to allow a one-to-one mapping from +call site addresses to the primary hash table. +Thus our hash function is trivial to calculate and collisions +occur only for call sites that call multiple +destinations (e.g. functional parameters and functional variables). +A one level hash function using both call site and callee would +result in an unreasonably large hash table. +Further, the number of dynamic call sites and callees is not known during +execution of the profiled program. +.pp +Not all callers and callees can be identified by the monitoring +routine. +Routines that were compiled without the profiling augmentations +will not call the monitoring routine as part of their prologue, +and thus no arcs will be recorded whose destinations are in these +routines. +One need not profile all the routines in a program. +Routines that are not profiled run at full speed. +Certain routines, notably exception handlers, are invoked by +non-standard calling sequences. +Thus the monitoring routine may know the destination of an arc +(the callee), +but find it difficult or +impossible to determine the source of the arc (the caller). +Often in these cases the apparent source of the arc is not a call +site at all. +Such anomalous invocations are declared ``spontaneous''. +.sh 2 "Execution Times" +.pp +The execution times for routines can be gathered in at least two +ways. +One method measures the execution time of a routine by measuring +the elapsed time from routine entry to routine exit. +Unfortunately, time measurement is complicated on time-sharing +systems by the time-slicing of the program. +A second method samples the value of the program counter at some +interval, and infers execution time from the distribution of the +samples within the program. +This technique is particularly suited to time-sharing systems, +where the time-slicing can serve as the basis for sampling +the program counter. +Notice that, whereas the first method could provide exact timings, +the second is inherently a statistical approximation. +.pp +The sampling method need not require support from the operating +system: all that is needed is the ability to set and respond to +``alarm clock'' interrupts that run relative to program time. +It is imperative that the intervals be uniform since the +sampling of the program counter rather than the duration of the +interval is the basis of the distribution. +If sampling is done too often, the interruptions to sample the +program counter will overwhelm the running of the profiled program. +On the other hand, the program must run for enough sampled +intervals that the distribution of the samples accurately +represents the distribution of time for the execution of the +program. +As with routine call tracing, the monitoring routine can not +afford to output information for each program counter +sample. +In our computing environment, the operating system can provide a +histogram of the location of the program counter at the end of +each clock tick (1/60th of a second) in which a program runs. +The histogram is assembled in memory as the program runs. +This facility is enabled by our monitoring routine. +We have adjusted the granularity of the histogram so that +program counter values map one-to-one onto the histogram. +We make the simplifying assumption that all calls to a specific +routine require the same amount of time to execute. +This assumption may disguise that some calls +(or worse, some call sites) always invoke a routine +such that its execution is faster (or slower) +than the average time for that routine. +.pp +When the profiled program terminates, +the arc table and the histogram of +program counter samples is written to a file. +The arc table is condensed to consist of the source and destination +addresses of the arc and the count of the number of times the arc +was traversed by this execution of the program. +The recorded histogram consists of counters of the number of +times the program counter was found to be in each of the ranges covered +by the histogram. +The ranges themselves are summarized as a +lower and upper bound and a step size. diff --git a/usr.bin/gprof/PSD.doc/header.me b/usr.bin/gprof/PSD.doc/header.me new file mode 100644 index 0000000..aef606d --- /dev/null +++

+.EQ +delim $$ +gsize 11 +.EN +.sh 1 "Post Processing" +.pp +Having gathered the arcs of the call graph and timing information +for an execution of the program, +we are interested in attributing the time for each routine to the +routines that call it. +We build a dynamic call graph with arcs from caller to callee, +and propagate time from descendants to ancestors +by topologically sorting the call graph. +Time propagation is performed from the leaves of the +call graph toward the roots, according to the order +assigned by a topological numbering algorithm. +The topological numbering ensures that +all edges in the graph go from higher numbered nodes to lower +numbered nodes. +An example is given in Figure 1. +If we propagate time from nodes in the +order assigned by the algorithm, +execution time can be propagated from descendants to ancestors +after a single traversal of each arc in the call graph. +Each parent receives some fraction of a child's time. +Thus time is charged to the +caller in addition to being charged to the callee. +.(z +.so postp1.pic +.ce 2 +Topological ordering +Figure 1. +.ce 0 +.)z +.pp +Let $C sub e$ be the number of calls to some routine, +$e$, and $C sub e sup r$ be the number of +calls from a caller $r$ to a callee $e$. +Since we are assuming each call to a routine takes the +average amount of time for all calls to that routine, +the caller is accountable for +$C sub e sup r / C sub e$ +of the time spent by the callee. +Let the $S sub e$ be the $selftime$ of a routine, $e$. +The selftime of a routine can be determined from the +timing information gathered during profiled program execution. +The total time, $T sub r$, we wish to account to a routine +$r$, is then given by the recurrence equation: +.EQ +T sub r ~ = ~ {S sub r} ~ + ~ + sum from {r ~ roman CALLS ~ e} + {T sub e times {{C sub e sup r} over {C sub e}}} +.EN +where $r ~ roman CALLS ~ e$ is a relation showing all routines +$e$ called by a routine $r$. +This relation is easily available from the call graph. +.pp +However, if the execution contains recursive calls, +the call graph has cycles that +cannot be topologically sorted. +In these cases, we discover strongly-connected +components in the call graph, +treat each such component as a single node, +and then sort the resulting graph. +We use a variation of Tarjan's strongly-connected +components algorithm +that discovers strongly-connected components as it is assigning +topological order numbers [Tarjan72]. +.pp +Time propagation within strongly connected +components is a problem. +For example, a self-recursive routine +(a trivial cycle in the call graph) +is accountable for all the time it +uses in all its recursive instantiations. +In our scheme, this time should be +shared among its call graph parents. +The arcs from a routine to itself are of interest, +but do not participate in time propagation. +Thus the simple equation for time propagation +does not work within strongly connected components. +Time is not propagated from one member of a cycle to another, +since, by definition, this involves propagating time from a routine +to itself. +In addition, children of one member of a cycle +must be considered children of all members of the cycle. +Similarly, parents of one member of the cycle must inherit +all members of the cycle as descendants. +It is for these reasons that we collapse connected components. +Our solution collects all members of a cycle together, +summing the time and call counts for all members. +All calls into the cycle are made to share the total +time of the cycle, and all descendants of the cycle +propagate time into the cycle as a whole. +Calls among the members of the cycle +do not propagate any time, +though they are listed in the call graph profile. +.pp +Figure 2 shows a modified version of the call graph of Figure 1, +in which the nodes labelled 3 and 7 in Figure 1 are mutually +recursive. +The topologically sorted graph after the cycle is collapsed is +given in Figure 3. +.(z +.so postp2.pic +.ce 2 +Cycle to be collapsed. +Figure 2. +.ce 0 +.)z +.(z +.so postp3.pic +.ce 2 +Topological numbering after cycle collapsing. +Figure 3. +.ce 0 +.)z +.pp +Since the technique described above only collects the +dynamic call graph, +and the program typically does not call every routine +on each execution, +different executions can introduce different cycles in the +dynamic call graph. +Since cycles often have a significant effect on time propagation, +it is desirable to incorporate the static call graph so that cycles +will have the same members regardless of how the program runs. +.pp +The static call graph can be constructed from the source text +of the program. +However, discovering the static call graph from the source text +would require two moderately difficult steps: +finding the source text for the program +(which may not be available), +and scanning and parsing that text, +which may be in any one of several languages. +.pp +In our programming system, +the static calling information is also contained in the +executable version of the program, +which we already have available, +and which is in language-independent form. +One can examine the instructions +in the object program, +looking for calls to routines, and note which +routines can be called. +This technique allows us to add arcs to those already in the +dynamic call graph. +If a statically discovered arc already exists in the dynamic call +graph, no action is required. +Statically discovered arcs that do not exist in the dynamic call +graph are added to the graph with a traversal count of zero. +Thus they are never responsible for any time propagation. +However, they may affect the structure of the graph. +Since they may complete strongly connected components, +the static call graph construction is +done before topological ordering. diff --git a/usr.bin/gprof/PSD.doc/postp1.pic

+.sh 1 "Data Presentation" +.pp +The data is presented to the user in two different formats. +The first presentation simply lists the routines +without regard to the amount of time their descendants use. +The second presentation incorporates the call graph of the +program. +.sh 2 "The Flat Profile +.pp +The flat profile consists of a list of all the routines +that are called during execution of the program, +with the count of the number of times they are called +and the number of seconds of execution time for which they +are themselves accountable. +The routines are listed in decreasing order of execution time. +A list of the routines that are never called during execution of +the program is also available +to verify that nothing important is omitted by +this execution. +The flat profile gives a quick overview of the routines that are used, +and shows the routines that are themselves responsible +for large fractions of the execution time. +In practice, +this profile usually shows that no single function +is overwhelmingly responsible for +the total time of the program. +Notice that for this profile, +the individual times sum to the total execution time. +.sh 2 "The Call

program, +but we are limited by the two-dimensional nature of our output +devices. +We cannot assume that a call graph is planar, +and even if it is, that we can print a planar version of it. +Instead, we choose to list each routine, +together with information about +the routines that are its direct parents and children. +This listing presents a window into the call graph. +Based on our experience, +both parent information and child information +is important, +and should be available without searching +through the output. +.pp +The major entries of the call graph profile are the entries from the +flat profile, augmented by the time propagated to each +routine from its descendants. +This profile is sorted by the sum of the time for the routine +itself plus the time inherited from its descendants. +The profile shows which of the higher level routines +spend large portions of the total execution time +in the routines that they call. +For each routine, we show the amount of time passed by each child +to the routine, which includes time for the child itself +and for the descendants of the child +(and thus the descendants of the routine). +We also show the percentage these times represent of the total time +accounted to the child. +Similarly, the parents of each routine are listed, +along with time, +and percentage of total routine time, +propagated to each one. +.pp +Cycles are handled as single entities. +The cycle as a whole is shown as though it were a single routine, +except that members of the cycle are listed in place of the children. +Although the number of calls of each member +from within the cycle are shown, +they do not affect time propagation. +When a child is a member of a cycle, +the time shown is the appropriate fraction of the time +for the whole cycle. +Self-recursive routines have their calls broken +down into calls from the outside and self-recursive calls. +Only the outside calls affect the propagation of time. +.pp +The following example is a typical fragment of a call graph. +.(b +.so pres1.pic +.)b +The entry in the call graph profile listing for this example is +shown in Figure 4. +.pp +The entry is for routine \s-1EXAMPLE\s+1, which has +the Caller routines as its parents, +and the Sub routines as its children. +The reader should keep in mind that all information +is given \fIwith respect to \s-1EXAMPLE\s+1\fP. +The index in the first column shows that \s-1EXAMPLE\s+1 +is the second entry in the profile listing. +The \s-1EXAMPLE\s+1 routine is called ten times, four times by \s-1CALLER1\s+1, +and six times by \s-1CALLER2\s+1. +Consequently 40% of \s-1EXAMPLE\s+1's time is propagated to \s-1CALLER1\s+1, +and 60% of \s-1EXAMPLE\s+1's time is propagated to \s-1CALLER2\s+1. +The self and descendant fields of the parents +show the amount of self and descendant time \s-1EXAMPLE\s+1 +propagates to them (but not the time used by +the parents directly). +Note that \s-1EXAMPLE\s+1 calls itself recursively four times. +The routine \s-1EXAMPLE\s+1 calls routine \s-1SUB1\s+1 twenty times, \s-1SUB2\s+1 once, +and never calls \s-1SUB3\s+1. +Since \s-1SUB2\s+1 is called a total of five times, +20% of its self and descendant time is propagated to \s-1EXAMPLE\s+1's +descendant time field. +Because \s-1SUB1\s+1 is a member of \fIcycle 1\fR, +the self and descendant times +and call count fraction +are those for the cycle as a whole. +Since cycle 1 is called a total of forty times +(not counting calls among members of the cycle), +it propagates 50% of the cycle's self and descendant +time to \s-1EXAMPLE\s+1's descendant time field. +Finally each name is followed by an index that shows +where on the listing to find the entry for that routine. +.sh 1 "Using the Profiles" +.pp +The profiler is a useful tool for improving +a set of routines that implement an abstraction. +It can be helpful in identifying poorly coded routines, +and in evaluating the new algorithms and code that replace them. +Taking full advantage of the profiler +requires a careful examination of the call graph profile, +and a thorough knowledge of the abstractions underlying +the program. +.pp +The easiest optimization that can be performed +is a small change +to a control construct or data structure that improves the +running time of the program. +An obvious starting point +is a routine that is called many times. +For example, suppose an output +routine is the only parent +of a routine that formats the data. +If this format routine is expanded inline in the +output routine, the overhead of a function call and +return can be saved for each datum that needs to be formatted. +.pp +The drawback to inline expansion is that the data abstractions +in the program may become less parameterized, +hence less clearly defined. +The profiling will also become less useful since the loss of +routines will make its output more granular. +For example, +if the symbol table functions ``lookup'', ``insert'', and ``delete'' +are all merged into a single parameterized routine, +it will be impossible to determine the costs +of any one of these individual functions from the profile. +.pp +Further potential for optimization lies in routines that +implement data abstractions whose total execution +time is long. +For example, a lookup routine might be called only a few +times, but use an inefficient linear search algorithm, +that might be replaced with a binary search. +Alternately, the discovery that a rehashing function is being +called excessively, can lead to a different +hash function or a larger hash table. +If the data abstraction function cannot easily be speeded up, +it may be advantageous to cache its results, +and eliminate the need to rerun +it for identical inputs. +These and other ideas for program improvement are discussed in +[Bentley81]. +.pp +This tool is best used in an iterative approach: +profiling the program, +eliminating one bottleneck, +then finding some other part of the program +that begins to dominate execution time. +For instance, we have used \fBgprof\fR on itself; +eliminating, rewriting, and inline expanding routines, +until reading +data files (hardly a target for optimization!) +represents the dominating factor in its execution time. +.pp +Certain types of programs are not easily analyzed by \fBgprof\fR. +They are typified by programs that exhibit a large degree of +recursion, such as recursive descent compilers. +The problem is that most of the major routines are grouped +into a single monolithic cycle. +As in the symbol table abstraction that is placed +in one routine, +it is impossible to distinguish which members of the cycle are +responsible for the execution time. +Unfortunately there are no easy modifications to these programs that +make them amenable to analysis. +.pp +A completely different use of the profiler is to analyze the control +flow of an unfamiliar program. +If you receive a program from another user that you need to modify +in some small way, +it is often unclear where the changes need to be made. +By running the program on an example and then using \fBgprof\fR, +you can get a view of the structure of the program. +.pp +Consider an example in which you need to change the output format +of the program. +For purposes of this example suppose that the call graph +of the output portion of the program has the following structure: +.(b +.so pres2.pic +.)b +Initially you look through the \fBgprof\fR +output for the system call ``\s-1WRITE\s+1''. +The format routine you will need to change is probably +among the parents of the ``\s-1WRITE\s+1'' procedure. +The next step is to look at the profile entry for each +of parents of ``\s-1WRITE\s+1'', +in this example either ``\s-1FORMAT1\s+1'' or ``\s-1FORMAT2\s+1'', +to determine which one to change. +Each format routine will have one or more parents, +in this example ``\s-1CALC1\s+1'', ``\s-1CALC2\s+1'', and ``\s-1CALC3\s+1''. +By inspecting the source code for each of these routines +you can determine which format routine generates the output that +you wish to modify. +Since the \fBgprof\fR entry shows all the +potential calls to the format routine you intend to change, +you can determine if your modifications will affect output that +should be left alone. +If you desire to change the output of ``\s-1CALC2\s+1'', but not ``\s-1CALC3\s+1'', +then formatting routine ``\s-1FORMAT2\s+1'' needs to be split +into two separate routines, +one of which implements the new format. +You can then retarget just the call by ``\s-1CALC2\s+1'' +that needs the new format. +It should be noted that the static call information is particularly +useful here since the test case you run probably will not +exercise the entire program. +.sh 1 "Conclusions" +.pp +We have created a profiler that aids in the evaluation +of modular programs. +For each routine in the program, +the profile shows the extent to which that routine +helps support various abstractions, +and how that routine uses other abstractions. +The profile accurately assesses the cost of routines +at all levels of the program decomposition. +The profiler is easily used, +and can be compiled into the program without any prior planning by +the programmer. +It adds only five to thirty percent execution overhead to the program +being profiled, +produces no additional output until after the program finishes, +and allows the program to be measured in its actual environment. +Finally, the profiler runs on a time-sharing system +using only the normal services provided by the operating system +and compilers. diff --git a/usr.bin/gprof/PSD.doc/profiling.me

+produces an execution profile of C, Pascal, or Fortran77 programs. +The effect of called routines is incorporated in the profile of each caller. +The profile data is taken from the call graph profile file +.Pf ( Pa gmon.out +default) which is created by programs +that are compiled with the +.Fl pg +option of +.Xr cc 1 , +.Xr pc 1 , +and +.Xr f77 1 . +The +.Fl pg +option also links in versions of the library routines +that are compiled for profiling. +.Nm Gprof +reads the given object file (the default is +.Pa a.out) +and establishes the relation between it's symbol table +and the call graph profile from +.Pa gmon.out . +If more than one profile file is specified, +the +.Nm gprof +output shows the sum of the profile information in the given profile files. +.Pp +.Nm Gprof +calculates the amount of time spent in each routine. +Next, these times are propagated along the edges of the call graph. +Cycles are discovered, and calls into a cycle are made to share the time +of the cycle. +The first listing shows the functions +sorted according to the time they represent +including the time of their call graph descendents. +Below each function entry is shown its (direct) call graph children, +and how their times are propagated to this function. +A similar display above the function shows how this function's time and the +time of its descendents is propagated to its (direct) call graph parents. +.Pp +Cycles are also shown, with an entry for the cycle as a whole and +a listing of the members of the cycle and their contributions to the +time and call counts of the cycle. +.Pp +Second, a flat profile is given, +similar to that provided by +.Xr prof 1 . +This listing gives the total execution times, the call counts, +the time in milleseconds the call spent in the routine itself, and +the time in milleseconds the call spent in the routine itself including +its descendents. +.Pp +Finally, an index of the function names is provided. +.Pp +The following options are available: +.Bl -tag -width Fl +.It Fl a +Suppresses the printing of statically declared functions. +If this option is given, all relevant information about the static function +(e.g., time samples, calls to other functions, calls from other functions) +belongs to the function loaded just before the static function in the +.Pa a.out +file. +.It Fl b +Suppresses the printing of a description of each field in the profile. +.It Fl c +The static call graph of the program is discovered by a heuristic +that examines the text space of the object file. +Static-only parents or children are shown +with call counts of 0. +.It Fl C Ar count +Find a minimal set of arcs that can be broken to eliminate all cycles with +.Ar count +or more members. +Caution: the algorithm used to break cycles is exponential, +so using this option may cause +.Nm gprof +to run for a very long time. +.It Fl e Ar name +Suppresses the printing of the graph profile entry for routine +.Ar name +and all its descendants +(unless they have other ancestors that aren't suppressed). +More than one +.Fl e +option may be given. +Only one +.Ar name +may be given with each +.Fl e +option. +.It Fl E Ar name +Suppresses the printing of the graph profile entry for routine +.Ar name +(and its descendants) as +.Fl e , +above, and also excludes the time spent in +.Ar name +(and its descendants) from the total and percentage time computations. +(For example, +.Fl E +.Ar mcount +.Fl E +.Ar mcleanup +is the default.) +.It Fl f Ar name +Prints the graph profile entry of only the specified routine +.Ar name +and its descendants. +More than one +.Fl f +option may be given. +Only one +.Ar name +may be given with each +.Fl f +option. +.It Fl F Ar name +Prints the graph profile entry of only the routine +.Ar name +and its descendants (as +.Fl f , +above) and also uses only the times of the printed routines +in total time and percentage computations. +More than one +.Fl F +option may be given. +Only one +.Ar name +may be given with each +.Fl F +option. +The +.Fl F +option +overrides +the +.Fl E +option. +.It Fl k Ar fromname Ar toname +Will delete any arcs from routine +.Ar fromname +to routine +.Ar toname . +This can be used to break undesired cycles. +More than one +.Fl k +option may be given. +Only one pair of routine names may be given with each +.Fl k +option. +.It Fl s +A profile file +.Pa gmon.sum +is produced that represents +the sum of the profile information in all the specified profile files. +This summary profile file may be given to later +executions of gprof (probably also with a +.Fl s ) +to accumulate profile data across several runs of an +.Pa a.out +file. +.It Fl z +Displays routines that have zero usage (as shown by call counts +and accumulated time). +This is useful

format_file +.Op Fl n Ar length +.Bk -words +.Op Fl s Ar skip +.Ek +.Ar file ... +.Sh DESCRIPTION +The hexdump utility is a filter which displays the specified files, or +the standard input, if no files are specified, in a user specified +format. +.Pp +The options are as follows: +.Bl -tag -width Fl +.It Fl b +.Em One-byte octal display . +Display the input offset in hexadecimal, followed by sixteen +space-separated, three column, zero-filled, bytes of input data, +in octal, per line. +.It Fl c +.Em One-byte character display . +Display the input offset in hexadecimal, followed by sixteen +space-separated, three column, space-filled, characters of input +data per line. +.It Fl d +.Em Two-byte decimal display. +Display the input offset in hexadecimal, followed by eight +space-separated, five column, zero-filled, two-byte units +of input data, in unsigned decimal, per line. +.It Fl e Ar format_string +Specify a format string to be used for displaying data. +.It Fl f Ar format_file +Specify a file that contains one or more newline separated format strings. +Empty lines and lines whose first non-blank character is a hash mark +.Pf ( Cm \&# ) +are ignored. +.It Fl n Ar length +Interpret only +.Ar length +bytes of input. +.It Fl o +.Em Two-byte octal display. +Display the input offset in hexadecimal, followed by eight +space-separated, six column, zero-filled, two byte quantities of +input data, in octal, per line. +.It Fl s Ar offset +Skip +.Ar offset +bytes from the beginning of the input. +By default, +.Ar offset +is interpreted as a decimal number. +With a leading +.Cm 0x +or +.Cm 0X , +.Ar offset +is interpreted as a hexadecimal number, +otherwise, with a leading +.Cm 0 , +.Ar offset +is interpreted as an octal number. +Appending the character +.Cm b , +.Cm k , +or +.Cm m +to +.Ar offset +causes it to be interpreted as a multiple of +.Li 512 , +.Li 1024 , +or +.Li 1048576 , +respectively. +.It Fl v +The +.Fl v +option causes hexdump to display all input data. +Without the +.Fl v +option, any number of groups of output lines, which would be +identical to the immediately preceding group of output lines (except +for the input offsets), are replaced with a line comprised of a +single asterisk. +.It Fl x +.Em Two-byte hexadecimal display. +Display the input offset in hexadecimal, followed by eight, space +separated, four column, zero-filled, two-byte quantities of input +data, in hexadecimal, per line. +.El +.Pp +For each input file, +.Nm hexdump +sequentially copies the input to standard output, transforming the +data according to the format strings specified by the +.Fl e +and +.Fl f +options, in the order that they were specified. +.Ss Formats +A format string contains any number of format units, separated by +whitespace. +A format unit contains up to three items: an iteration count, a byte +count, and a format. +.Pp +The iteration count is an optional positive integer, which defaults to +one. +Each format is applied iteration count times. +.Pp +The byte count is an optional positive integer. +If specified it defines the number of bytes to be interpreted by +each iteration of the format. +.Pp +If an iteration count and/or a byte count is specified, a single slash +must be placed after the iteration count and/or before the byte count +to disambiguate them. +Any whitespace before or after the slash is ignored. +.Pp +The format is required and must be surrounded by double quote +(" ") marks. +It is interpreted as a fprintf-style format string (see +.Xr fprintf 3 ) , +with the +following exceptions: +.Bl -bullet -offset indent +.It +An asterisk (*) may not be used as a field width or precision. +.It +A byte count or field precision +.Em is +required for each ``s'' conversion +character (unlike the +.Xr fprintf 3 +default which prints the entire string if the precision is unspecified). +.It +The conversion characters ``h'', ``l'', ``n'', ``p'' and ``q'' are +not supported. +.It +The single character escape sequences +described in the C standard are supported: +.Bd -ragged -offset indent -compact +.Bl -column +.It NUL \e0 +.It \ea +.It \eb +.It \ef +.It \en +.It \er +.It \et +.It \ev +.El +.Ed +.El +.Pp +Hexdump also supports the the following additional conversion strings: +.Bl -tag -width Fl +.It Cm \&_a Ns Op Cm dox +Display the input offset, cumulative across input files, of the +next byte to be displayed. +The appended characters +.Cm d , +.Cm o , +and +.Cm x +specify the display base +as decimal, octal or hexadecimal respectively. +.It Cm \&_A Ns Op Cm dox +Identical to the +.Cm \&_a +conversion string except that it is only performed +once, when all of the input data has been processed. +.It Cm \&_c +Output characters in the default character set. +Nonprinting characters are displayed in three character, zero-padded +octal, except for those representable by standard escape notation +(see above), +which are displayed as two character strings. +.It Cm _p +Output characters in the default character set. +Nonprinting characters are displayed as a single +.Dq Cm \&. . +.It Cm _u +Output US ASCII characters, with the exception that control characters are +displayed using the following, lower-case, names. +Characters greater than 0xff, hexadecimal, are displayed as hexadecimal +strings. +.Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo +.It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq +.It \&006\ ack\t007\ bel\t008\ bs\t009\ ht\t00A\ lf\t00B\ vt +.It \&00C\ ff\t00D\ cr\t00E\ so\t00F\ si\t010\ dle\t011\ dc1

supported byte counts for the conversion characters +are as follows: +.Bl -tag -width "Xc,_Xc,_Xc,_Xc,_Xc,_Xc" -offset indent +.It Li \&%_c , \&%_p , \&%_u , \&%c +One byte counts only. +.It Xo +.Li \&%d , \&%i , \&%o , +.Li \&%u , \&%X , \&%x +.Xc +Four byte default, one, two and four byte counts supported. +.It Xo +.Li \&%E , \&%e , \&%f , +.Li \&%G , \&%g +.Xc +Eight byte default, four byte counts supported. +.El +.Pp +The amount of data interpreted by each format string is the sum of the +data required by each format unit, which is the iteration count times the +byte count, or the iteration count times the number of bytes required by +the format if the byte count is not specified. +.Pp +The input is manipulated in ``blocks'', where a block is defined as the +largest amount of data specified by any format string. +Format strings interpreting less than an input block's worth of data, +whose last format unit both interprets some number of bytes and does +not have a specified iteration count, have the iteration count +incremented until the entire input block has been processed or there +is not enough data remaining in the block to satisfy the format string. +.Pp +If, either as a result of user specification or hexdump modifying +the iteration count as described above, an iteration count is +greater than one, no trailing whitespace characters are output +during the last iteration. +.Pp +It is an error to specify a byte count as well as multiple conversion +characters or strings unless all but one of the conversion characters +or strings is +.Cm \&_a +or +.Cm \&_A . +.Pp +If, as a result of the specification of the +.Fl n +option or end-of-file being reached, input data only partially +satisfies a format string, the input block is zero-padded sufficiently +to display all available data (i.e. any format units overlapping the +end of data will display some number of the zero bytes). +.Pp +Further output by such format strings is replaced by an equivalent +number of spaces. +An equivalent number of spaces is defined as the number of spaces +output by an +.Cm s +conversion character with the same field width +and precision as the original conversion character or conversion +string but with any +.Dq Li \&+ , +.Dq \&\ \& , +.Dq Li \&# +conversion flag characters +removed, and referencing a NULL string. +.Pp +If no format strings are specified, the default display is equivalent +to specifying the +.Fl x +option. +.Pp +.Nm hexdump +exits 0 on success and >0 if an error occurred. +.Sh EXAMPLES +Display the input in perusal format: +.Bd -literal

I was wrong in my original +observation (or mis-observation :-). UCB did keep the Illinois +copyright intact. + +The issue still is whether we can distribute indent, and if we can, which +version. David Willcox (the author) states that: + +| Several people have asked me on what basis I claim that indent is in +| the public domain. I knew I would be sorry I made that posting. +| +| Some history. Way back in 1976, the project I worked on at the +| University of Illinois Center for Advanced Computation had a huge +| battle about how to format C code. After about a week of fighting, I +| got disgusted and wrote a program, which I called indent, to reformat C +| code. It had a bunch of different options that would let you format +| the output the way you liked. In particular, all of the different +| formats being championed were supported. +| +| It was my first big C program. It was ugly. It wasn't designed, it +| just sort of grew. But it pretty much worked, and it stopped most of +| the fighting. +| +| As a matter of form, I included a University of Illinois Copyright +| notice. However, my understanding was that, since the work was done +| on an ARPA contract, it was in the public domain. +| +| Time passed. Some years later, indent showed up on one of the early +| emacs distributions. +| +| Later still, someone from UC Berlekey called the UofI and asked if +| indent was in the public domain. They wanted to include it in their +| UNIX distributions, along with the emacs stuff. I was no longer at the +| UofI, but Rob Kolstad, who was, asked me about it. I told him I didn't +| care if they used it, and since then it has been on the BSD distributions. +| +| Somewhere along the way, several other unnamed people have had their +| hands in it. It was converted to understand version 7 C. (The +| original was version 6.) It was converted from its original filter +| interface to its current "blow away the user's file" interface. +| The $HOME/.indent.pro file parsing was added. Some more formatting +| options were added. +| +| The source I have right now has two copyright notices. One is the +| original from the UofI. One is from Berkeley. +| +| I am not a lawyer, and I certainly do not understand copyright law. As +| far as I am concerned, the bulk of this program, everything covered by +| the UofI copyright, is in the public domain, and worth every penny. +| Berkeley's copyright probably should only cover their changes, and I +| don't know their feelings about sending it out. + +In any case, there appears to be noone at UofI to clarify/and change +that copyright, but I am confident (based on the statements of its +author) that the code, as it stands with its copyright, is +distributable, and will not cause any legal problems. + +Hence, the issue reduces to *which* one to distribute through +comp.sources.unix. I would suggest that with the permission of you +folks (given that you have parts copyrighted), we distribute the 4.3 +version of indent, which appears to be the most up-to-date version. I +happen to have just about every known version of indent, including the +very original submission from the author to a unix tape, later the +G-Emacs version, any 4.n version, sun version and the Unipress +version. I still think we should not have to "go-back-in-time" and +re-do all the work you people have done. + +I hope to hear from you as to what you think about this. You may of +course send 4.3 version to the moderator directly, or you can let me +know of your permission, and I will send the sources, or you can let +me know that 4.3 version is off-limits, in which case we would probably +have to revert to an older version. One way or another, I hope to get +a version of indent to comp.sources.unix. + +regards.. oz + +cc: ccvaxa!willcox + sun.com!jar + uunet!rsalz + diff --git a/usr.bin/indent/args.c b/usr.bin/indent/args.c new file mode 100644 index 0000000..e62f038 --- /dev/null +++ b/usr.bin/indent/args.c @@ -0,0 +1,300 @@ +/* + * Copyright (c) 1985 Sun Microsystems, Inc. + * Copyright (c) 1980, 1993 + * The Regents of the University of California.

It reformats the +.Ar C +program in the +.Ar input-file +according to the switches. The switches which can be +specified are described below. They may appear before or after the file +names. +.Pp +.Sy NOTE : +If you only specify an +.Ar input-file , +the formatting is +done `in-place', that is, the formatted file is written back into +.Ar input-file +and a backup copy of +.Ar input-file +is written in the current directory. If +.Ar input-file +is named +.Sq Pa /blah/blah/file , +the backup file is named +.Pa file.BAK . +.Pp +If +.Ar output-file +is specified, +.Nm indent +checks to make sure it is different from +.Ar input-file . +.Pp +The options listed below control the formatting style imposed by +.Nm indent . +.Bl -tag -width Op +.It Fl bad , nbad +If +.Fl bad +is specified, a blank line is forced after every block of +declarations. Default: +.Fl nbad . +.It Fl bap , nbap +If +.Fl bap +is specified, a blank line is forced after every procedure body. Default: +.Fl nbap . +.It Fl bbb , nbbb +If +.Fl bbb +is specified, a blank line is forced before every block comment. Default: +.Fl nbbb . +.It Fl \&bc , nbc +If +.Fl \&bc +is specified, then a newline is forced after each comma in a declaration. +.Fl nbc +turns off this option. The default is +.Fl \&bc . +.It Fl \&br , \&bl +Specifying +.Fl \&bl +lines up compound statements like this: +.ne 4 +.Bd -literal -offset indent +if (...) +{ + code +} +.Ed +.Pp +Specifying +.Fl \&br +(the default) makes them look like this: +.ne 3 +.Bd -literal -offset indent +if (...) { + code +} +.Ed +.Pp +.It Fl c n +The column in which comments on code start. The default is 33. +.It Fl cd n +The column in which comments on declarations start. The default +is for these comments to start in the same column as those on code. +.It Fl cdb , ncdb +Enables (disables) the placement of comment delimiters on blank lines. With +this option enabled, comments look like this: +.Bd -literal -offset indent +.ne 3 + /* + * this is a comment + */ +.Ed +.Pp +Rather than like this: +.Bd -literal -offset indent + /* this is a comment */ +.Ed +.Pp +This only affects block comments, not comments to the right of +code. The default is +.Fl cdb . +.It Fl ce , nce +Enables (disables) forcing `else's to cuddle up to the immediately preceding +`}'. The default is +.Fl \&ce . +.It Fl \&ci Ns Ar n +Sets the continuation indent to be +.Ar n . +Continuation +lines will be indented that far from the beginning of the first line of the +statement. Parenthesized expressions have extra indentation added to +indicate the nesting, unless +.Fl \&lp +is in effect. +.Fl \&ci +defaults to the same value as +.Fl i . +.It Fl cli Ns Ar n +Causes case labels to be indented +.Ar n +tab stops to the right of the containing +.Ic switch +statement. +.Fl cli0 .5 +causes case labels to be indented half a tab stop. The +default is +.Fl cli0 . +.It Fl d Ns Ar n +Controls the placement of comments which are not to the +right of code. The default +.Fl \&d\&1 +means that such comments are placed one indentation level to the +left of code. Specifying +.Fl \&d\&0 +lines up these comments with the code. See the section on comment +indentation below. +.It Fl \&di Ns Ar n +Specifies the indentation, in character positions, from a declaration keyword +to the following identifier. The default is +.Fl di16 . +.It Fl dj , ndj +.Fl \&dj +left justifies declarations. +.Fl ndj +indents declarations the same as code. The default is +.Fl ndj . +.It Fl \&ei , nei +Enables (disables) special +.Ic else-if +processing. If it's enabled, an +.Ic if +following an +.Ic else +will have the same indentation as the preceding +.Ic \&if +statement. +.It Fl fc1 , nfc1 +Enables (disables) the formatting of comments that start in column 1. +Often, comments whose leading `/' is in column 1 have been carefully +hand formatted by the programmer. In such cases, +.Fl nfc1 +should be +used. The default is +.Fl fc1 . +.It Fl i Ns Ar n +The number of spaces for one indentation level. The default is 4. +.It Fl \&ip , nip +Enables (disables) the indentation of parameter declarations from the left +margin. The default is +.Fl \&ip . +.It Fl l Ns Ar n +Maximum length of an output line. The default is 75. +.It Fl \&lp , nlp +Lines up code surrounded by parenthesis in continuation lines. If a line +has a left paren which is not closed on that line, then continuation lines +will be lined up to start at the character position just after the left +paren. For example, here is how a piece of continued code looks with +.Fl nlp +in effect: +.ne 2 +.Bd -literal -offset indent +p1 = first_procedure(second_procedure(p2, p3), +\ \ third_procedure(p4,p5)); +.Ed +.Pp +.ne 5 +With +.Fl lp +in effect (the default) the code looks somewhat clearer: +.Bd -literal -offset indent +p1\ =\ first_procedure(second_procedure(p2,\ p3), +\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ third_procedure(p4,p5)); +.Ed +.Pp +.ne 5 +Inserting two more newlines we get: +.Bd -literal -offset indent +p1\ =\ first_procedure(second_procedure(p2, +\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ p3), +\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ third_procedure(p4 +\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ p5)); +.Ed +.It Fl npro +Causes the profile files, +.Sq Pa ./.indent.pro +and +.Sq Pa ~/.indent.pro , +to be ignored. +.It Fl pcs , npcs +If true +.Pq Fl pcs +all procedure calls will have a space inserted between +the name and the `('. The default is +.Fl npcs . +.It Fl psl , npsl +If true +.Pq Fl psl +the names of procedures being defined are placed in +column 1 \- their types, if any, will be left on the previous lines. The +default is +.Fl psl . +.It Fl \&sc , nsc +Enables (disables) the placement of asterisks (`*'s) at the left edge of all +comments. +.It Fl sob , nsob +If +.Fl sob +is specified, indent will swallow optional blank lines. You can use this to +get rid of blank lines after declarations. Default: +.Fl nsob . +.It Fl \&st +Causes +.Nm indent +to take its input from stdin, and put its output to stdout. +.It Fl T Ns Ar typename +Adds +.Ar typename +to the list of type keywords. Names accumulate: +.Fl T +can be specified more than once. You need to specify all the typenames that +appear in your program that are defined by +.Ic typedef +\- nothing will be +harmed if you miss a few, but the program won't be formatted as nicely as +it should. This sounds like a painful thing to have to do, but it's really +a symptom of a problem in C: +.Ic typedef +causes a syntactic change in the +language and +.Nm indent +can't find all +instances of +.Ic typedef . +.It Fl troff +Causes +.Nm indent +to format the program for processing by +.Xr troff 1 . +It will produce a fancy +listing in much the same spirit as +.Xr vgrind 1 . +If the output file is not specified, the default is standard output, +rather than formatting in place. +.It Fl v , \&nv +.Fl v +turns on `verbose' mode; +.Fl \&nv +turns it off. When in verbose mode, +.Nm indent +reports when it splits one line of input into two or more lines of output, +and gives some size statistics at completion. The default is +.Fl \&nv . +.El +.Pp +You may set up your own `profile' of defaults to +.Nm indent +by creating a file called +.Pa .indent.pro +in your login directory and/or the current directory and including +whatever switches you like. A `.indent.pro' in the current directory takes +precedence over the one in your login directory. If +.Nm indent +is run and a profile file exists, then it is read to set up the program's +defaults. Switches on the command line, though, always override profile +switches. The switches should be separated by spaces, tabs or newlines. +.Pp +.Ss Comments +.Sq Em Box +.Em comments . +.Nm Indent +assumes that any comment with a dash or star immediately after the start of +comment (that is, `/*\-' or `/**') is a comment surrounded by a box of stars. +Each line of such a comment is left unchanged, except that its indentation +may be adjusted to account for the change in indentation of the first line +of the comment. +.Pp +.Em Straight text . +All other comments are treated as straight text. +.Nm Indent +fits as many words (separated by blanks, tabs, or newlines) on a +line as possible. Blank lines break paragraphs. +.Pp +.Ss Comment indentation +If a comment is on a line with code it is started in the `comment column', +which is set by the +.Fl c Ns Ns Ar n +command line parameter. Otherwise, the comment is started at +.Ar n +indentation levels less than where code is currently being placed, where +.Ar n +is specified by the +.Fl d Ns Ns Ar n +command line parameter. If the code on a line extends past the comment +column, the comment starts further to the right, and the right margin may be +automatically extended in extreme cases. +.Pp +.Ss Preprocessor lines +In general, +.Nm indent +leaves preprocessor lines alone. The only +reformatting that it will do is to straighten up trailing comments. It +leaves embedded comments alone. Conditional compilation +.Pq Ic #ifdef...#endif +is recognized and +.Nm indent +attempts to correctly +compensate for the syntactic peculiarities introduced. +.Pp +.Ss C syntax +.Nm Indent +understands a substantial amount about the syntax of C, but it +has a `forgiving' parser. It attempts to cope with the usual sorts of +incomplete and misformed syntax. In particular, the use of macros like: +.Pp +.Dl #define forever for(;;) +.Pp +is handled properly. +.Sh ENVIRONMENT +.Nm Indent +uses the +.Ev HOME +environment variable. +.Sh FILES +.Bl -tag -width "./.indent.pro" -compact +.It Pa ./.indent.pro +profile file +.It Pa ~/.indent.pro +profile file +.El +.Sh HISTORY +The +.Nm indent +command appeared in +.Bx 4.2 . +.Sh BUGS +.Nm Indent +has even more switches than +.Xr ls 1 . +.Pp +.ne 5 +A common mistake that often causes grief is typing: +.Pp +.Dl indent *.c +.Pp +to the shell in an attempt to indent all the +.Nm C +programs in a directory. +This is probably a bug, not a feature. diff --git a/usr.bin/indent/indent.c b/usr.bin/indent/indent.c new file mode 100644 index 0000000..132d21f --- /dev/null +++ b/usr.bin/indent/indent.c @@ -0,0 +1,1181 @@ +/* + * Copyright (c) 1985 Sun Microsystems, Inc. + * Copyright (c) 1976 Board of Trustees of the University of Illinois. + * Copyright (c) 1980, 1993 + * The Regents of the University of California.

The + loader collects all of these elements at load time and outputs a + vector for each name. + Space (an array of 32 bit words) is allocated for the set in the + data section, and the n_value field of each set element value is + stored into one word of the array. + The first word of the array is the length of the set (number of + elements). The last word of the vector is set to zero for possible + use by incremental loaders. The array is ordered by the linkage + order; the first symbols which the linker encounters will be first + in the array. + + In C syntax this looks like: + + struct set_vector { + unsigned int length; + unsigned int vector[length]; + unsigned int always_zero; + }; + + Before being placed into the array, each element is relocated + according to its type. This allows the loader to create an array + of pointers to objects automatically. N_SETA type symbols will not + be relocated. + + The address of the set is made into an N_SETV symbol + whose name is the same as the name of the set. + This symbol acts like a N_DATA global symbol + in that it can satisfy undefined external references. + + For the purposes of determining whether or not to load in a library + file, set element definitions are not considered "real + definitions"; they will not cause the loading of a library + member. + + If relocatable output is requested, none of this processing is + done. The symbols are simply relocated and passed through to the + output file. + + So, for example, the following three lines of assembler code + (whether in one file or scattered between several different ones) + will produce a three element vector (total length is five words; + see above), referenced by the symbol "_xyzzy", which will have the + addresses of the routines _init1, _init2, and _init3. + + *NOTE*: If symbolic addresses are used in the n_value field of the + defining .stabs, those symbols must be defined in the same file as + that containing the .stabs. + + .stabs "_xyzzy",23,0,0,_init1 + .stabs "_xyzzy",23,0,0,_init2 + .stabs "_xyzzy",23,0,0,_init3 + + Note that (23 == (N_SETT | N_EXT)). */ + +#ifndef N_SETA +#define N_SETA 0x14 /* Absolute set element symbol */ +#endif /* This is input to LD, in a .o file. */ + +#ifndef N_SETT +#define N_SETT 0x16 /* Text set element symbol */ +#endif /* This is input to LD, in a .o file. */ + +#ifndef N_SETD +#define N_SETD 0x18 /* Data set element symbol */ +#endif /* This is input to LD, in a .o file. */ + +#ifndef N_SETB +#define N_SETB 0x1A /* Bss set element symbol */ +#endif /* This is input to LD, in a .o file. */ + +/* Macros dealing with the set element symbols defined in a.out.h */ +#define SET_ELEMENT_P(x) ((x)>=N_SETA&&(x)<=(N_SETB|N_EXT)) +#define TYPE_OF_SET_ELEMENT(x) ((x)-N_SETA+N_ABS) + +#ifndef N_SETV +#define N_SETV 0x1C /* Pointer to set vector in data area. */ +#endif /* This is output from LD. */ + +/* If a this type of symbol is encountered, its name is a warning + message to print each time the symbol referenced by the next symbol + table entry is referenced. + + This feature may be used to allow backwards compatibility with + certain functions (eg. gets) but to discourage programmers from + their use. + + So if, for example, you wanted to have ld print a warning whenever + the function "gets" was used in their C program, you would add the + following to the assembler file in which gets is defined: + + .stabs "Obsolete function \"gets\" referenced",30,0,0,0 + .stabs "_gets",1,0,0,0 + + These .stabs do not necessarily have to be in the same file as the + gets function, they simply must exist somewhere in the compilation. */ + +#ifndef N_WARNING +#define N_WARNING 0x1E /* Warning message to print if symbol + included */ +#endif /* This is input to ld */ + +#ifndef __GNU_STAB__ + +/* Line number for the data section.

In addition, it provides a set of +.i ed -\c +like commands for manipulating messages and sending mail. +.i Mail +offers the user simple editing capabilities to ease the composition +of outgoing messages, as well as providing the ability to define and send +to names which address groups of users. Finally, +.i Mail +is able to send and receive messages across such networks as the +ARPANET, UUCP, and Berkeley network. +.pp +This document describes how to use the +.i Mail +program to send and receive messages. The reader is not assumed to +be familiar with other message handling systems, but should be +familiar with the \s-2UNIX\s0\** +.(f +\** \s-1UNIX\s0 is a trademark of Bell Laboratories. +.)f +shell, the text editor, and some of the common \s-2UNIX\s0 commands. +.q "The \s-2UNIX\s0 Programmer's Manual," +.q "An Introduction to Csh," +and +.q "Text Editing with Ex and Vi" +can be consulted for more information on these topics. +.pp +Here is how messages are handled: +the mail system accepts incoming +.i messages +for you from other people +and collects them in a file, called your +.i "system mailbox" . +When you login, the system notifies you if there are any messages +waiting in your system mailbox. If you are a +.i csh +user, you will be notified when new mail arrives if you inform +the shell of the location of your mailbox. On version 7 systems, +your system mailbox is located in the directory /usr/spool/mail +in a file with your login name. If your login name is +.q sam, +then you can make +.i csh +notify you of new mail by including the following line in your .cshrc +file: +.(l +set mail=/usr/spool/mail/sam +.)l +When you read your mail using +.i Mail , +it reads your system mailbox and separates that file into the +individual messages that have been sent to you. You can then +read, reply to, delete, or save these messages. +Each message is marked with its author and the date they sent it. diff --git a/usr.bin/mail/USD.doc/mail2.nr b/usr.bin/mail/USD.doc/mail2.nr new file mode 100644 index 0000000..f64aaa6 --- /dev/null +++ b/usr.bin/mail/USD.doc/mail2.nr @@ -0,0 +1,617 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

Sending mail is simple: to send a +message to a user whose login name is, say, +\*(lqroot,\*(rq +use the shell +command: +.(l +% Mail root +.)l +then type your message. When you reach the end of the message, type +an EOT (control\-d) at the beginning of a line, which will cause +.i Mail +to echo \*(lqEOT\*(rq and return you to the Shell. When the user you sent mail +to next logs in, he will receive the message: +.(l +You have mail. +.)l +to alert him to the existence of your message. +.pp +If, while you are composing the message +you decide that you do not wish to send it after all, you can +abort the letter with a \s-2RUBOUT\s0. Typing a single \s-2RUBOUT\s0 +causes +.i Mail +to print +.(l +(Interrupt -- one more to kill letter) +.)l +Typing a second +\s-2RUBOUT\s0 causes +.i Mail +to save your partial letter on the file +.q dead.letter +in your home directory and abort the letter. +Once you have +sent mail to someone, there is no way to undo the act, so be +careful. +.pp +The message your recipient reads will consist of the message you +typed, preceded by a line telling who sent the message (your login name) +and the date and time it +was sent. +.pp +If you want to send the same message to several other people, you can list +their login names on the command line. +Thus, +.(l +% Mail sam bob john +Tuition fees are due next Friday. Don't forget!! + +EOT +% +.)l +will send the reminder to sam, bob, and john. +.pp +If, when you log in, you see the message, +.(l +You have mail. +.)l +you can read the mail by typing simply: +.(l +% Mail +.)l +.i Mail +will respond by typing its version number and date and then listing +the messages you have waiting. Then it will type a prompt and await +your command. The messages are assigned numbers starting with 1 \*- you +refer to the messages with these numbers. +.i Mail +keeps track of which messages are +.i new +(have been sent since you last read your mail) and +.i read +(have been read by you). New messages have an +.b N +next to them in the header listing and old, but unread messages have +a +.b U +next to them. +.i Mail +keeps track of new/old and read/unread messages by putting a +header field called +.q Status +into your messages. +.pp +To look at a specific message, use the +.b type +command, which may be abbreviated to simply +.b t . +For example, if you had the following messages: +.(l +N 1 root Wed Sep 21 09:21 "Tuition fees" +N 2 sam Tue Sep 20 22:55 +.)l +you could examine the first message by giving the command: +.(l +type 1 +.)l +which might cause +.i Mail +to respond with, for example: +.(l +Message 1: +From root Wed Sep 21 09:21:45 1978 +Subject: Tuition fees +Status: R + +Tuition fees are due next Wednesday. Don't forget!! + +.)l +Many +.i Mail +commands that operate on messages take a message number as an +argument like the +.b type +command. For these commands, there is a notion of a current +message. When you enter the +.i Mail +program, the current message is initially the first one. Thus, +you can often omit the message number and use, for example, +.(l +t +.)l +to type the current message. As a further shorthand, you can type a message +by simply giving its message number. Hence, +.(l +1 +.)l +would type the first message. +.pp +Frequently, it is useful to read the messages in your mailbox in order, +one after another. You can read the next message in +.i Mail +by simply typing a newline. As a special case, you can type a newline +as your first command to +.i Mail +to type the first message. +.pp +If, after typing a message, you wish to immediately send a reply, +you can do so with the +.b reply +command. +.b Reply , +like +.b type , +takes a message number as an argument. +.i Mail +then begins a message addressed to the user who sent you the message. +You may then type in your letter in reply, followed by a +at the beginning of a line, as before. +.i Mail +will type EOT, then type the ampersand prompt to indicate its readiness +to accept another command. In our example, if, after typing the +first message, you wished to reply to it, you might give the command: +.(l +reply +.)l +.i Mail +responds by typing: +.(l +To: root +Subject: Re: Tuition fees +.)l +and waiting for you to enter your letter. +You are now in the message collection mode described at the beginning +of this section and +.i Mail +will gather up your message up to a control\-d. +Note that it copies the subject +header from the original message. This is useful in that correspondence +about a particular matter will tend to retain the same subject heading, +making it easy to recognize. If there are other header fields in +the message, the information found will also be used. +For example, if the letter had a +.q "To:" +header listing several recipients, +.i Mail +would arrange to send your replay to the same people as well. +Similarly, if the original message contained a +.q "Cc:" +(carbon copies to) field, +.i Mail +would send your reply to +.i those +users, too. +.i Mail +is careful, though, not too send the message to +.i you , +even if you appear in the +.q "To:" +or +.q "Cc:" +field, unless you ask to be included explicitly. See section 4 for more +details. +.pp +After typing in your letter, the dialog with +.i Mail +might look like the following: +.(l +reply +To: root +Subject: Tuition fees + +Thanks for the reminder +EOT +& +.)l +.pp +The +.b reply +command is especially useful for sustaining extended conversations +over the message system, with other +.q listening +users receiving copies of the conversation. The +.b reply +command can be abbreviated to +.b r . +.pp +Sometimes you will receive a message that has been sent to +several people and wish to reply +.i only +to the person who sent it. +.b Reply +with a capital +.b R +replies to a message, but sends a copy to the sender only. +.pp +If you wish, while reading your mail, to send a message to someone, +but not as a reply to one of your messages, you can send the message +directly with the +.b mail +command, which takes as arguments the names of the recipients you wish +to send to. For example, to send a message to +.q frank, +you would do: +.(l +mail frank +This is to confirm our meeting next Friday at 4. +EOT +& +.)l +The +.b mail +command can be abbreviated to +.b m . +.pp +Normally, each message you receive is saved in the file +.i mbox +in your login directory at the time you leave +.i Mail . +Often, +however, you will not want to save a particular message you +have received because it is only of passing interest. To avoid +saving a message in +.i mbox +you can delete it using the +.b delete +command. In our example, +.(l +delete 1 +.)l +will prevent +.i Mail +from saving message 1 (from root) in +.i mbox . +In addition to not saving deleted messages, +.i Mail +will not let +you type them, either. The effect is to make the message disappear +altogether, along with its number. The +.b delete +command can be abbreviated to simply +.b d . +.pp +Many features of +.i Mail +can be tailored to your liking with the +.b set +command. The +.b set +command has two forms, depending on whether you are setting +a +.i binary +option or a +.i valued +option. +Binary options are either on or off. For example, the +.q ask +option informs +.i Mail +that each time you send a message, you want it to prompt you for +a subject header, to be included in the message. +To set the +.q ask +option, you would type +.(l +set ask +.)l +.pp +Another useful +.i Mail +option is +.q hold. +Unless told otherwise, +.i Mail +moves the messages from your system mailbox to the file +.i mbox +in your home directory when you leave +.i Mail . +If you want +.i Mail +to keep your letters in the system mailbox instead, you can set the +.q hold +option. +.pp +Valued options are values which +.i Mail +uses to adapt to your tastes. For example, the +.q SHELL +option tells +.i Mail +which shell you like to use, and is specified by +.(l +set SHELL=/bin/csh +.)l +for example. Note that no spaces are allowed in +.q "SHELL=/bin/csh." +A complete list of the +.i Mail +options appears in section 5. +.pp +Another important valued option is +.q crt. +If you use a fast video terminal, you will find that when you +print long messages, they fly by too quickly for you to read them. +With the +.q crt +option, you can make +.i Mail +print any message larger than a given number of lines by sending +it through a paging program. This program is specified by the +valued option \fBPAGER\fP. +If \fBPAGER\fP is not set, a default paginator is used. +For example, most CRT users with 24-line screens should do: +.(l +set crt=24 +.)l +to paginate messages that will not fit on their screens. +In the default state, \fImore\fP (default paginator) prints a screenful of +information, then types --More--. Type a space to see the next screenful. +.pp +Another adaptation to user needs that +.i Mail +provides is that of +.i aliases . +An alias is simply a name which stands for one or more +real user names. +.i Mail +sent to an alias is really sent to the list of real users +associated with it. For example, an alias can be defined for the +members of a project, so that you can send mail to the whole project +by sending mail to just a single name. The +.b alias +command in +.i Mail +defines an alias. Suppose that the users in a project are +named Sam, Sally, Steve, and Susan. To define an alias called +.q project +for them, you would use the +.i Mail +command: +.(l +alias project sam sally steve susan +.)l +The +.b alias +command can also be used to provide a convenient name for someone +whose user name is inconvenient. For example, if a user named +.q "Bob Anderson" +had the login name +.q anderson," +you might want to use: +.(l +alias bob anderson +.)l +so that you could send mail to the shorter name, +.q bob. +.pp +While the +.b alias +and +.b set +commands allow you to customize +.i Mail , +they have the drawback that they must be retyped each time you enter +.i Mail . +To make them more convenient to use, +.i Mail +always looks for two files when it is invoked. It first reads +a system wide file +.q /usr/lib/Mail.rc, +then a user specific file, +.q .mailrc, +which is found in the user's home directory. +The system wide file +is maintained by the system administrator and +contains +.b set +commands that are applicable to all users of the system. +The +.q .mailrc +file is usually used by each user to set options the way he likes +and define individual aliases. +For example, my .mailrc file looks like this: +.(l +set ask nosave SHELL=/bin/csh +.)l +As you can see, it is possible to set many options in the +same +.b set +command. The +.q nosave +option is described in section 5. +.pp +Mail aliasing is implemented +at the system-wide level +by the mail delivery +system +.i sendmail . +These aliases are stored in the file /usr/lib/aliases and are +accessible to all users of the system. +The lines in /usr/lib/aliases are of +the form: +.(l +alias: name\*<1\*>, name\*<2\*>, name\*<3\*> +.)l +where +.i alias +is the mailing list name and the +.i name\* +are the members of the list. Long lists can be continued onto the next +line by starting the next line with a space or tab. Remember that you +must execute the shell command +.i newaliases +after editing /usr/lib/aliases since the delivery system +uses an indexed file created by +.i newaliases . +.pp +We have seen that +.i Mail +can be invoked with command line arguments which are people +to send the message to, or with no arguments to read mail. +Specifying the +.rb \-f +flag on the command line causes +.i Mail +to read messages from a file other than your system mailbox. +For example, if you have a collection of messages in +the file +.q letters +you can use +.i Mail +to read them with: +.(l +% Mail \-f letters +.)l +You can use all +the +.i Mail +commands described in this document to examine, modify, or delete +messages from your +.q letters +file, which will be rewritten when you leave +.i Mail +with the +.b quit +command described below. +.pp +Since mail that you read is saved in the file +.i mbox +in your home directory by default, you can read +.i mbox +in your home directory by using simply +.(l +% Mail \-f +.)l +.pp +Normally, messages that you examine using the +.b type +command are saved in the file +.q mbox +in your home directory if you leave +.i Mail +with the +.b quit +command described below. +If you wish to retain a message in your system mailbox +you can use the +.b preserve +command to tell +.i Mail +to leave it there. +The +.b preserve +command accepts a list of message numbers, just like +.b type +and may be abbreviated to +.b pre . +.pp +Messages in your system mailbox that you do not examine are +normally retained in your system mailbox automatically. +If you wish to have such a message saved in +.i mbox +without reading it, you may use the +.b mbox +command to have them so saved. For example, +.(l +mbox 2 +.)l +in our example would cause the second message (from sam) +to be saved in +.i mbox +when the +.b quit +command is executed. +.b Mbox +is also the way to direct messages to your +.i mbox +file if you have set the +.q hold +option described above. +.b Mbox +can be abbreviated to +.b mb . +.pp +When you have perused all the messages of interest, you can leave +.i Mail +with the +.b quit +command, which saves the messages you have typed but not +deleted in the file +.i mbox +in your login directory. Deleted messages are discarded irretrievably, +and messages left untouched are preserved in your system mailbox so +that you will see them the next time you type: +.(l +% Mail +.)l +The +.b quit +command can be abbreviated to simply +.b q . +.pp +If you wish for some reason to leave +.i Mail +quickly without altering either your system mailbox or +.i mbox , +you can type the +.b x +command (short for +.b exit ), +which will immediately return you to the Shell without changing anything. +.pp +If, instead, you want to execute a Shell command without leaving +.i Mail , +you +can type the command preceded by an exclamation point, just as in the +text editor. Thus, for instance: +.(l +!date +.)l +will print the current date without leaving +.i Mail . +.pp +Finally, the +.b help +command is available to print out a brief summary of the +.i Mail +commands, using only the single character command abbreviations. diff --git a/usr.bin/mail/USD.doc/mail3.nr b/usr.bin/mail/USD.doc/mail3.nr new file mode 100644 index 0000000..64f7634 --- /dev/null +++ b/usr.bin/mail/USD.doc/mail3.nr @@ -0,0 +1,133 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

This section describes this facility. +.pp +To use the folder facility, you must tell +.i Mail +where you wish to keep your folders. Each folder of messages will +be a single file. For convenience, all of your folders are kept in +a single directory of your choosing. To tell +.i Mail +where your folder directory is, put a line of the form +.(l +set folder=letters +.)l +in your +.i .mailrc +file. If, as in the example above, your folder directory does not +begin with a `/,' +.i Mail +will assume that your folder directory is to be found starting from +your home directory. Thus, if your home directory is +.b /usr/person +the above example told +.i Mail +to find your folder directory in +.b /usr/person/letters . +.pp +Anywhere a file name is expected, you can use a folder name, preceded +with `+.' For example, to put a message into a folder with the +.b save +command, you can use: +.(l +save +classwork +.)l +to save the current message in the +.i classwork +folder. If the +.i classwork +folder does not yet exist, it will be created. Note that messages +which are saved with the +.b save +command are automatically removed from your system mailbox. +.pp +In order to make a copy of a message in a folder without causing +that message to be removed from your system mailbox, use the +.b copy +command, which is identical in all other respects to the +.b save +command. For example, +.(l +copy +classwork +.)l +copies the current message into the +.i classwork +folder and leaves a copy in your system mailbox. +.pp +The +.b folder +command +can be used to direct +.i Mail +to the contents of a different folder. +For example, +.(l +folder +classwork +.)l +directs +.i Mail +to read the contents of the +.i classwork +folder. All of the commands that you can use on your system +mailbox are also applicable to folders, including +.b type , +.b delete , +and +.b reply . +To inquire which folder you are currently editing, use simply: +.(l +folder +.)l +.pp +To list your current set of folders, use the +.b folders +command. +.pp +To start +.i Mail +reading one of your folders, you can use the +.b \-f +option described in section 2. For example: +.(l +% Mail \-f +classwork +.)l +will cause +.i Mail +to read your +.i classwork +folder without looking at your system mailbox. diff --git a/usr.bin/mail/USD.doc/mail4.nr b/usr.bin/mail/USD.doc/mail4.nr new file mode 100644 index 0000000..b67bf03 --- /dev/null +++ b/usr.bin/mail/USD.doc/mail4.nr @@ -0,0 +1,437 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

For +example, to print the text of the message so far, use: +.(l +~p +.)l +which will print a line of dashes, the recipients of your message, and +the text of the message so far. +Since +.i Mail +requires two consecutive \s-2RUBOUT\s0's to abort a letter, you +can use a single \s-2RUBOUT\s0 to abort the output of ~p or any other +~ escape without killing your letter. +.pp +If you are dissatisfied with the message as +it stands, you can invoke the text editor on it using the escape +.(l +~e +.)l +which causes the message to be copied into a temporary file and an +instance of the editor to be spawned. After modifying the message to +your satisfaction, write it out and quit the editor. +.i Mail +will respond +by typing +.(l +(continue) +.)l +after which you may continue typing text which will be appended to your +message, or type to end the message. +A standard text editor is provided by +.i Mail . +You can override this default by setting the valued option +.q EDITOR +to something else. For example, you might prefer: +.(l +set EDITOR=/usr/ucb/ex +.)l +.pp +Many systems offer a screen editor as an alternative to the standard +text editor, such as the +.i vi +editor from UC Berkeley. +To use the screen, or +.i visual +editor, on your current message, you can use the escape, +.(l +~v +.)l +~v works like ~e, except that the screen editor is invoked instead. +A default screen editor is defined by +.i Mail . +If it does not suit you, you can set the valued option +.q VISUAL +to the path name of a different editor. +.pp +It is often useful to be able to include the contents of some +file in your message; the escape +.(l +~r filename +.)l +is provided for this purpose, and causes the named file to be appended +to your current message. +.i Mail +complains if the file doesn't exist +or can't be read. If the read is successful, the number of lines and +characters appended to your message is printed, after which you may continue +appending text. The filename may contain shell metacharacters like * and ? +which are expanded according to the conventions of your shell. +.pp +As a special case of ~r, the escape +.(l +~d +.)l +reads in the file +.q dead.letter +in your home directory. This is often useful since +.i Mail +copies the text +of your message there when you abort a message with \s-2RUBOUT\s0. +.pp +To save the current text of your message on a file you may use the +.(l +~w filename +.)l +escape. +.i Mail +will print out the number of lines and characters written +to the file, after which you may continue appending text to your message. +Shell metacharacters may be used in the filename, as in ~r and are expanded +with the conventions of your shell. +.pp +If you are sending mail from within +.i Mail's +command mode +you can read a message sent to you into the message +you are constructing with the escape: +.(l +~m 4 +.)l +which will read message 4 into the current message, shifted right by +one tab stop. You can name any non-deleted message, or list of messages. +Messages can also be forwarded without shifting by a tab stop with ~f. +This is the usual way to forward a message. +.pp +If, in the process of composing a message, you decide to add additional +people to the list of message recipients, you can do so with the escape +.(l +~t name1 name2 ... +.)l +You may name as few or many additional recipients as you wish. Note +that the users originally on the recipient list will still receive +the message; you cannot remove someone from the recipient +list with ~t. +.pp +If you wish, you can associate a subject with your message by using the +escape +.(l +~s Arbitrary string of text +.)l +which replaces any previous subject with +.q "Arbitrary string of text." +The subject, if given, is sent near the +top of the message prefixed with +.q "Subject:" +You can see what the message will look like by using ~p. +.pp +For political reasons, one occasionally prefers to list certain +people as recipients of carbon copies of a message rather than +direct recipients. The escape +.(l +~c name1 name2 ... +.)l +adds the named people to the +.q "Cc:" +list, similar to ~t. +Again, you can execute ~p to see what the message will look like. +.pp +The escape +.(l +~b name1 name2 ... +.)l +adds the named people to the +.q "Cc:" +list, but does not make the names visible in the +.q "Cc:" +line ("blind" carbon copy). +.pp +The recipients of the message together constitute the +.q "To:" +field, the subject the +.q "Subject:" +field, and the carbon copies the +.q "Cc:" +field. If you wish to edit these in ways impossible with the ~t, ~s, ~c +and ~b escapes, you can use the escape +.(l +~h +.)l +which prints +.q "To:" +followed by the current list of recipients and leaves the cursor +(or printhead) at the end of the line. If you type in ordinary +characters, they are appended to the end of the current list of +recipients. You can also use your erase character to erase back into +the list of recipients, or your kill character to erase them altogether. +Thus, for example, if your erase and kill characters are the standard +(on printing terminals) # and @ symbols, +.(l +~h +To: root kurt####bill +.)l +would change the initial recipients +.q "root kurt" +to +.q "root bill." +When you type a newline, +.i Mail +advances to the +.q "Subject:" +field, where the same rules apply. Another newline brings you to +the +.q "Cc:" +field, which may be edited in the same fashion. Another newline +brings you to the +.q "Bcc:" +("blind" carbon copy) field, which follows the same rules as the "Cc:" +field. Another newline +leaves you appending text to the end of your message. You can use +~p to print the current text of the header fields and the body +of the message. +.pp +To effect a temporary escape to the shell, the escape +.(l +~!command +.)l +is used, which executes +.i command +and returns you to mailing mode without altering the text of +your message. If you wish, instead, to filter the body of your +message through a shell command, then you can use +.(l +~|command +.)l +which pipes your message through the command and uses the output +as the new text of your message. If the command produces no output, +.i Mail +assumes that something is amiss and retains the old version +of your message. A frequently-used filter is the command +.i fmt , +designed to format outgoing mail. +.pp +To effect a temporary escape to +.i Mail +command mode instead, you can use the +.(l +~:\fIMail command\fP +.)l +escape. This is especially useful for retyping the message you are +replying to, using, for example: +.(l +~:t +.)l +It is also useful for setting options and modifying aliases. +.pp +If you wish abort the current message, you can use the escape +.(l +~q +.)l +This will terminate the current message and return you to the +shell (or \fIMail\fP if you were using the \fBmail\fP command). +If the \fBsave\fP option is set, the message will be copied +to the file +.q dead.letter +in your home directory. +.pp +If you wish (for some reason) to send a message that contains +a line beginning with a tilde, you must double it. Thus, for example, +.(l +~~This line begins with a tilde. +.)l +sends the line +.(l +~This line begins with a tilde. +.)l +.pp +Finally, the escape +.(l +~? +.)l +prints out a brief summary of the available tilde escapes. +.pp +On some terminals (particularly ones with no lower case) +tilde's are difficult to type. +.i Mail +allows you to change the escape character with the +.q escape +option. For example, I set +.(l +set escape=] +.)l +and use a right bracket instead of a tilde. If I ever need to +send a line beginning with right bracket, I double it, just as for ~. +Changing the escape character removes the special meaning of ~. +.sh 2 "Network access" +.pp +This section describes how to send mail to people on other machines. +Recall that sending to a plain login name sends mail to that person +on your machine. If your machine is directly (or sometimes, even, +indirectly) connected to the Arpanet, you can send messages to people +on the Arpanet using a name of the form +.(l +name@host.domain +.)l +where +.i name +is the login name of the person you're trying to reach, +.i host +is the name of the machine on the Arpanet, +and +.i domain +is the higher-level scope within which the hostname is known, e.g. EDU (for educational +institutions), COM (for commercial entities), GOV (for governmental agencies), +ARPA for many other things, BITNET or CSNET for those networks. +.pp +If your recipient logs in on a machine connected to yours by +UUCP (the Bell Laboratories supplied network that communicates +over telephone lines), sending mail can be a bit more complicated. +You must know the list of machines through which your message must +travel to arrive at his site. So, if his machine is directly connected +to yours, you can send mail to him using the syntax: +.(l +host!name +.)l +where, again, +.i host +is the name of the machine and +.i name +is the login name. +If your message must go through an intermediary machine first, you +must use the syntax: +.(l +intermediary!host!name +.)l +and so on. It is actually a feature of UUCP that the map of all +the systems in the network is not known anywhere (except where people +decide to write it down for convenience). Talk to your system administrator +about good ways to get places; the +.i uuname +command will tell you systems whose names are recognized, but not which +ones are frequently called or well-connected. +.pp +When you use the +.b reply +command to respond to a letter, there is a problem of figuring out the +names of the users in the +.q "To:" +and +.q "Cc:" +lists +.i "relative to the current machine" . +If the original letter was sent to you by someone on the local machine, +then this problem does not exist, but if the message came from a remote +machine, the problem must be dealt with. +.i Mail +uses a heuristic to build the correct name for each user relative +to the local machine. So, when you +.b reply +to remote mail, the names in the +.q "To:" +and +.q "Cc:" +lists may change somewhat. +.sh 2 "Special recipients" +.pp +As described previously, you can send mail to either user names or +.b alias +names. It is also possible to send messages directly to files or to +programs, using special conventions. If a recipient name has a +`/' in it or begins with a `+', it is assumed to be the +path name of a file into which +to send the message. If the file already exists, the message is +appended to the end of the file. If you want to name a file in +your current directory (ie, one for which a `/' would not usually +be needed) you can precede the name with `./' +So, to send mail to the file +.q memo +in the current directory, you can give the command: +.(l +% Mail ./memo +.)l +If the name begins with a `+,' it is expanded into the full path name +of the folder name in your folder directory. +This ability to send mail to files can be used for a variety of +purposes, such as maintaining a journal and keeping a record of +mail sent to a certain group of users. The second example can be +done automatically by including the full pathname of the record +file in the +.b alias +command for the group. Using our previous +.b alias +example, you might give the command: +.(l +alias project sam sally steve susan /usr/project/mail_record +.)l +Then, all mail sent to "project" would be saved on the file +.q /usr/project/mail_record +as well as being sent to the members of the project. This file +can be examined using +.i "Mail \-f" . +.pp +It is sometimes useful to send mail directly to a program, for +example one might write a project billboard program and want to access +it using +.i Mail . +To send messages to the billboard program, one can send mail +to the special name `|billboard' for example. +.i Mail +treats recipient names that begin with a `|' as a program to send +the mail to. An +.b alias +can be set up to reference a `|' prefaced name if desired. +.i Caveats : +the shell treats `|' specially, so it must be quoted on the command +line. Also, the `| program' must be presented as a single argument to +mail. The safest course is to surround the entire name with double +quotes. This also applies to usage in the +.b alias +command. For example, if we wanted to alias `rmsgs' to `rmsgs \-s' +we would need to say: +.(l +alias rmsgs "| rmsgs -s" +.)l diff --git a/usr.bin/mail/USD.doc/mail5.nr b/usr.bin/mail/USD.doc/mail5.nr new file mode 100644 index 0000000..b70ce95 --- /dev/null +++ b/usr.bin/mail/USD.doc/mail5.nr @@ -0,0 +1,1041 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

Message numbers may be either +decimal numbers, which directly specify messages, or one of the +special characters +.q \(ua +.q "." +or +.q "$" +to specify the first relevant, current, or last +relevant message, respectively. +.i Relevant +here means, for most commands +.q "not deleted" +and +.q "deleted" +for the +.b undelete +command. +.pp +A range of messages consists of two message numbers (of the form +described in the previous paragraph) separated by a dash. +Thus, to print the first four messages, use +.(l +type 1\-4 +.)l +and to print all the messages from the current message to the last +message, use +.(l +type .\-$ +.)l +.pp +A +.i name +is a user name. The user names given in the message list are +collected together and each message selected by other means +is checked to make sure it was sent by one of the named users. +If the message consists entirely of user names, then every +message sent by one of those users that is +.i relevant +(in the sense described earlier) +is selected. Thus, to print every message sent to you by +.q root, +do +.(l +type root +.)l +.pp +As a shorthand notation, you can specify simply +.q * +to get every +.i relevant +(same sense) +message. Thus, +.(l +type * +.)l +prints all undeleted messages, +.(l +delete * +.)l +deletes all undeleted messages, and +.(l +undelete * +.)l +undeletes all deleted messages. +.pp +You can search for the presence of a word in subject lines with +.b / . +For example, to print the headers of all messages that contain the +word +.q PASCAL, +do: +.(l +from /pascal +.)l +Note that subject searching ignores upper/lower case differences. +.sh 2 "List of commands" +.pp +This section describes all the +.i Mail +commands available when +receiving mail. +.ip "\fB\-\fP\ \ " +The +.rb \- +command goes to the previous message and prints it. The +.rb \- +command may be given a decimal number +.i n +as an argument, in which case the +.i n th +previous message is gone to and printed. +.ip "\fB?\fP\ \ " +Prints a brief summary of commands. +.ip "\fB!\fP\ \ " +Used to preface a command to be executed by the shell. +.ip "\fBPrint\fP\ \ " +Like +.b print , +but also print out ignored header fields. See also +\fBprint\fP, \fBignore\fP and \fBretain\fP. +\fBPrint\fP can be abbreviated to \fBP\fP. +.ip "\fBReply\fP or \fBRespond\fP\ \ " +Note the capital \fBR\fP in the name. +Frame a reply to a one or more messages. +The reply (or replies if you are using this on multiple messages) +will be sent ONLY to the person who sent you the message +(respectively, the set of people who sent the messages you are +replying to). +You can +add people using the \fB~t\fP, \fB~c\fP and \fB~b\fP +tilde escapes. The subject in your reply is formed by prefacing the +subject in the original message with +.q "Re:" +unless it already began thus. +If the original message included a +.q "reply-to" +header field, the reply will go +.i only +to the recipient named by +.q "reply-to." +You type in your message using the same conventions available to you +through the +.b mail +command. +The +.b Reply +command is especially useful for replying to messages that were sent +to enormous distribution groups when you really just want to +send a message to the originator. Use it often. +\fBReply\fP (and \fBRespond\fP) can be abbreviated to \fBR\fP. +.ip "\fBType\fP\ \ " +Identical to the +.b Print +command. +\fBType\fP can be abbreviated to \fBT\fP. +.ip "\fBalias\fP\ \ " +Define a name to stand for a set of other names. +This is used when you want to send messages to a certain +group of people and want to avoid retyping their names. +For example +.(l +alias project john sue willie kathryn +.)l +creates an alias +.i project +which expands to the four people John, Sue, Willie, and Kathryn. +If no arguments are given, all currently-defined aliases are printed. +If one argument is given, that alias is printed (if it exists). +\fBAlias\fP can be abbreviated to \fBa\fP. +.ip "\fBalternates\fP\ \ " +If you have accounts on several machines, you may find it convenient +to use the /usr/lib/aliases on all the machines except one to direct +your mail to a single account. +The +.b alternates +command is used to inform +.i Mail +that each of these other addresses is really +.i you . +.i Alternates +takes a list of user names and remembers that they are all actually you. +When you +.b reply +to messages that were sent to one of these alternate names, +.i Mail +will not bother to send a copy of the message to this other address (which +would simply be directed back to you by the alias mechanism). +If +.i alternates +is given no argument, it lists the current set of alternate names. +.b Alternates +is usually used in the .mailrc file. +\fBAlternates\fP can be abbreviated to \fBalt\fP. +.ip "\fBchdir\fP\ \ " +The +.b chdir +command allows you to change your current directory. +.b Chdir +takes a single argument, which is taken to be the pathname of +the directory to change to. If no argument is given, +.b chdir +changes to your home directory. +\fBChdir\fP can be abbreviated to \fBc\fP. +.ip "\fBcopy\fP\ \ " +The +.b copy +command does the same thing that +.b save +does, except that it does not mark the messages it is used on +for deletion when you quit. +\fBCopy\fP can be abbreviated to \fBco\fP. +.ip "\fBdelete\fP\ \ " +Deletes a list of messages. Deleted messages can be reclaimed +with the +.b undelete +command. +\fBDelete\fP can be abbreviated to \fBd\fP. +.ip "\fBdp\fP or \fBdt\fP\ \ " +These +commands delete the current message and print the next message. +They are useful for quickly reading and disposing of mail. +If there is no next message, \fImail\fP says ``at EOF.'' +.ip "\fBedit\fP\ \ " +To edit individual messages using the text editor, the +.b edit +command is provided. The +.b edit +command takes a list of messages as described under the +.b type +command and processes each by writing it into the file +Message\c +.i x +where +.i x +is the message number being edited and executing the text editor on it. +When you have edited the message to your satisfaction, write the message +out and quit, upon which +.i Mail +will read the message back and remove the file. +.b Edit +can be abbreviated to +.b e . +.ip "\fBelse\fP\ \ " +Marks the end of the then-part of an +.b if +statement and the beginning of the +part to take effect if the condition of the +.b if +statement is false. +.ip "\fBendif\fP\ \ " +Marks the end of an +.b if +statement. +.ip "\fBexit\fP or \fBxit\fP\ \ " +Leave +.i Mail +without updating the system mailbox or the file your were reading. +Thus, if you accidentally delete several messages, you can use +.b exit +to avoid scrambling your mailbox. +\fBExit\fP can be abbreviated to \fBex\fP or \fBx\fP. +.ip "\fBfile\fP\ \ " +The same as +.b folder . +\fBFile\fP can be abbreviated to \fBfi\fP. +.ip "\fBfolders\fP\ \ " +List the names of the folders in your folder directory. +.ip "\fBfolder\fP\ \ " +The +.b folder +command switches to a new mail file or folder. With no arguments, it +tells you which file you are currently reading. If you give +it an argument, it will write out changes (such as deletions) +you have made in the current file and read the new file. +Some special conventions are recognized for the name: +.(b +.TS +center; +c c +l a. +Name Meaning +_ +# Previous file read +% Your system mailbox +%name \fIName\fP's system mailbox +& Your ~/mbox file ++folder A file in your folder directory +.TE +.)b +\fBFolder\fP can be abbreviated to \fBfo\fP. +.ip "\fBfrom\fP\ \ " +The +.b from +command takes a list of messages and prints out the header lines for each one; +hence +.(l +from joe +.)l +is the easy way to display all the message headers from \*(lqjoe.\*(rq +\fBFrom\fP can be abbreviated to \fBf\fP. +.ip "\fBheaders\fP\ \ " +When you start up +.i Mail +to read your mail, it lists the message headers that you have. +These headers tell you who each message is from, when they were +received, how many lines and characters each message is, and the +.q "Subject:" +header field of each message, if present. In addition, +.i Mail +tags the message header of each message that has been the object +of the +.b preserve +command with a +.q P. +Messages that have been +.b saved +or +.b written +are flagged with a +.q *. +Finally, +.b deleted +messages are not printed at all. If you wish to reprint the current +list of message headers, you can do so with the +.b headers +command. The +.b headers +command (and thus the initial header listing) +only lists the first so many message headers. +The number of headers listed depends on the speed of your +terminal. +This can be overridden by specifying the number of headers you +want with the +.i window +option. +.i Mail +maintains a notion of the current +.q window +into your messages for the purposes of printing headers. +Use the +.b z +command to move forward and back a window. +You can move +.i Mail's +notion of the current window directly to a particular message by +using, for example, +.(l +headers 40 +.)l +to move +.i Mail's +attention to the messages around message 40. +If a ``+'' argument is given, then the next screenful of message headers is +printed, and if a ``\-'' argument is given, the previous screenful of message +headers is printed. +\fBHeaders\fP can be abbreviated to \fBh\fP. +.ip "\fBhelp\fP\ \ " +Print a brief and usually out of date help message about the commands +in +.i Mail . +The +.i man +page for +.i mail +is usually more up-to-date than either the help message or this manual. +It is also a synonym for \fB?\fP. +.ip "\fBhold\fP\ \ " +Arrange to hold a list of messages in the system mailbox, instead +of moving them to the file +.i mbox +in your home directory. If you set the binary option +.i hold , +this will happen by default. +It does not override the \fBdelete\fP command. +\fBHold\fP can be abbreviated to \fBho\fP. +.ip "\fBif\fP\ \ " +Commands in your +.q .mailrc +file can be executed conditionally depending on whether you are +sending or receiving mail with the +.b if +command. For example, you can do: +.(l +if receive + \fIcommands\fP... +endif +.)l +An +.b else +form is also available: +.(l +if send + \fIcommands\fP... +else + \fIcommands\fP... +endif +.)l +Note that the only allowed conditions are +.b receive +and +.b send . +.ip "\fBignore\fP \ \ " +.b N.B.: +.i Ignore +has been superseded by +.i retain. +.br +Add the list of header fields named to the +.i "ignore list" . +Header fields in the ignore list are not printed on your +terminal when you print a message. This allows you to suppress +printing of certain machine-generated header fields, such as +.i Via +which are not usually of interest. The +.b Type +and +.b Print +commands can be used to print a message in its entirety, including +ignored fields. +If +.b ignore +is executed with no arguments, it lists the current set of ignored fields. +.ip "\fBlist\fP\ \ " +List the valid +.i Mail +commands. +\fBList\fP can be abbreviated to \fBl\fP. +.. .ip \fBlocal\fP +.. Define a list of local names for this host. This command is useful +.. when the host is known by more than one name. Names in the list +.. may be qualified be the domain of the host. The first name on the local +.. list is the +.. .i distinguished +.. name of the host. +.. The names on the local list are used by +.. .i Mail +.. to decide which addresses are local to the host. +.. For example: +.. .(l +.. local ucbarpa.BERKELEY.ARPA arpa.BERKELEY.ARPA \\ +.. arpavax.BERKELEY.ARPA r.BERKELEY.ARPA \\ +.. ucb-arpa.ARPA +.. .)l +.. From this list we see that +.. .i "fred@ucbarpa.BERKELEY.ARPA", +.. .i "harold@arpa.BERKELEY", +.. and +.. .i "larry@r" +.. are all addresses of users on the local host. +.. The +.. .b local +.. command is usually not used be general users since it is designed for +.. local configuration; it is usually found in the file /usr/lib/Mail.rc. +.ip "\fBmail\fP\ \ " +Send mail to one or more people. If you have the +.i ask +option set, +.i Mail +will prompt you for a subject to your message. Then you +can type in your message, using tilde escapes as described in +section 4 to edit, print, or modify your message. To signal your +satisfaction with the message and send it, type control-d at the +beginning of a line, or a . alone on a line if you set the option +.i dot . +To abort the message, type two interrupt characters (\s-2RUBOUT\s0 +by default) in a row or use the +.b ~q +escape. +The \fBmail\fP command can be abbreviated to \fBm\fP. +.ip "\fBmbox\fP\ \ " +Indicate that a list of messages be sent to +.i mbox +in your home directory when you quit. This is the default +action for messages if you do +.i not +have the +.i hold +option set. +.ip "\fBnext\fP or \fB+\fP\ \ " +The +.b next +command goes to the next message and types it. If given a message list, +.b next +goes to the first such message and types it. Thus, +.(l +next root +.)l +goes to the next message sent by +.q root +and types it. The +.b next +command can be abbreviated to simply a newline, which means that one +can go to and type a message by simply giving its message number or +one of the magic characters +.q "^" +.q "." +or +.q "$". +Thus, +.(l +\&. +.)l +prints the current message and +.(l +4 +.)l +prints message 4, as described previously. +\fBNext\fP can be abbreviated to \fBn\fP. +.ip "\fBpreserve\fP\ \ " +Same as +.b hold . +Cause a list of messages to be held in your system mailbox when you quit. +\fBPreserve\fP can be abbreviated to \fBpre\fP. +.ip "\fBprint\fP\ \ " +Print the specified messages. If the +.b crt +variable is set, messages longer than the number of lines it indicates +are paged through the command specified by the \fBPAGER\fP variable. +The \fBprint\fP command can be abbreviated to \fBp\fP. +.ip "\fBquit\fP\ \ " +Terminates the session, saving all undeleted, unsaved and unwritten messages +in the user's \fImbox\fP file in their login directory +(messages marked as having been read), preserving all +messages marked with \fBhold\fP or \fBpreserve\fP or never referenced +in their system mailbox. +Any messages that were deleted, saved, written or saved to \fImbox\fP are +removed from their system mailbox. +If new mail has arrived during the session, the message +``You have new mail'' is given. If given while editing a mailbox file +with the \fB\-f\fP flag, then the edit file is rewritten. +A return to the Shell is effected, unless the rewrite of edit file fails, +in which case the user can escape with the \fBexit\fP command. +\fBQuit\fP can be abbreviated to \fBq\fP. +.ip "\fBreply\fP or \fBrespond\fP\ \ " +Frame a reply to a single message. +The reply will be sent to the +person who sent you the message (to which you are replying), plus all +the people who received the original message, except you. You can +add people using the \fB~t\fP, \fB~c\fP and \fB~b\fP +tilde escapes. The subject in your reply is formed by prefacing the +subject in the original message with +.q "Re:" +unless it already began thus. +If the original message included a +.q "reply-to" +header field, the reply will go +.i only +to the recipient named by +.q "reply-to." +You type in your message using the same conventions available to you +through the +.b mail +command. +The \fBreply\fP (and \fBrespond\fP) command can be abbreviated to \fBr\fP. +.ip "\fBretain\fP\ \ " +Add the list of header fields named to the \fIretained list\fP. +Only the header fields in the retain list +are shown on your terminal when you print a message. +All other header fields are suppressed. +The +.b Type +and +.b Print +commands can be used to print a message in its entirety. +If +.b retain +is executed with no arguments, it lists the current set of +retained fields. +.ip "\fBsave\fP\ \ " +It is often useful to be able to save messages on related topics +in a file. The +.b save +command gives you the ability to do this. The +.b save +command takes as an argument a list of message numbers, followed by +the name of the file in which to save the messages. The messages +are appended to the named file, thus allowing one to keep several +messages in the file, stored in the order they were put there. +The filename in quotes, followed by the line +count and character count is echoed on the user's terminal. +An example of the +.b save +command relative to our running example is: +.(l +s 1 2 tuitionmail +.)l +.b Saved +messages are not automatically saved in +.i mbox +at quit time, nor are they selected by the +.b next +command described above, unless explicitly specified. +\fBSave\fP can be abbreviated to \fBs\fP. +.ip "\fBset\fP\ \ " +Set an option or give an option a value. Used to customize +.i Mail . +Section 5.3 contains a list of the options. Options can be +.i binary , +in which case they are +.i on +or +.i off , +or +.i valued . +To set a binary option +.i option +.i on , +do +.(l +set option +.)l +To give the valued option +.i option +the value +.i value , +do +.(l +set option=value +.)l +There must be no space before or after the ``='' sign. +If no arguments are given, all variable values are printed. +Several options can be specified in a single +.b set +command. +\fBSet\fP can be abbreviated to \fBse\fP. +.ip "\fBshell\fP\ \ " +The +.b shell +command allows you to +escape to the shell. +.b Shell +invokes an interactive shell and allows you to type commands to it. +When you leave the shell, you will return to +.i Mail . +The shell used is a default assumed by +.i Mail ; +you can override this default by setting the valued option +.q SHELL, +eg: +.(l +set SHELL=/bin/csh +.)l +\fBShell\fP can be abbreviated to \fBsh\fP. +.ip "\fBsize\fP\ \ " +Takes a message list and prints out the size in characters of each +message. +.ip "\fBsource\fP\ \ " +The +.b source +command reads +.i mail +commands from a file. It is useful when you are trying to fix your +.q .mailrc +file and you need to re-read it. +\fBSource\fP can be abbreviated to \fBso\fP. +.ip "\fBtop\fP\ \ " +The +.b top +command takes a message list and prints the first five lines +of each addressed message. +If you wish, you can change the number of lines that +.b top +prints out by setting the valued option +.q "toplines." +On a CRT terminal, +.(l +set toplines=10 +.)l +might be preferred. +\fBTop\fP can be abbreviated to \fBto\fP. +.ip "\fBtype\fP\ \ " +Same as \fBprint\fP. +Takes a message list and types out each message on the terminal. +The \fBtype\fP command can be abbreviated to \fBt\fP. +.ip "\fBundelete\fP \ \" +Takes a message list and marks each message as \fInot\fP +being deleted. +\fBUndelete\fP can be abbreviated to \fBu\fP. +.ip "\fBunread\fP\ \ " +Takes a message list and marks each message as +.i not +having been read. +\fBUnread\fP can be abbreviated to \fBU\fP. +.ip "\fBunset\fP\ \ " +Takes a list of option names and discards their remembered values; +the inverse of \fBset\fP . +.ip "\fBvisual\fP\ \ " +It is often useful to be able to invoke one of two editors, +based on the type of terminal one is using. To invoke +a display oriented editor, you can use the +.b visual +command. The operation of the +.b visual +command is otherwise identical to that of the +.b edit +command. +.ne 2v+\n(psu +.sp \n(psu +Both the +.b edit +and +.b visual +commands assume some default text editors. These default editors +can be overridden by the valued options +.q EDITOR +and +.q VISUAL +for the standard and screen editors. You might want to do: +.(l +set EDITOR=/usr/ucb/ex VISUAL=/usr/ucb/vi +.)l +\fBVisual\fP can be abbreviated to \fBv\fP. +.ip "\fBwrite\fP\ \ " +The +.b save +command always writes the entire message, including the headers, +into the file. If you want to write just the message itself, you +can use the +.b write +command. The +.b write +command has the same syntax as the +.b save +command, and can be abbreviated to simply +.b w . +Thus, we could write the second message by doing: +.(l +w 2 file.c +.)l +As suggested by this example, the +.b write +command is useful for such tasks as sending and receiving +source program text over the message system. +The filename in quotes, followed by the line +count and character count is echoed on the user's terminal. +.ip "\fBz\fP\ \ " +.i Mail +presents message headers in windowfuls as described under +the +.b headers +command. +You can move +.i Mail's +attention forward to the next window by giving the +.(l +z+ +.)l +command. Analogously, you can move to the previous window with: +.(l +z\- +.)l +.sh 2 "Custom options" +.pp +Throughout this manual, we have seen examples of binary and valued options. +This section describes each of the options in alphabetical order, including +some that you have not seen yet. +To avoid confusion, please note that the options are either +all lower case letters or all upper case letters. When I start a sentence +such as: +.q "Ask" +causes +.i Mail +to prompt you for a subject header, +I am only capitalizing +.q ask +as a courtesy to English. +.ip "\fBEDITOR\fP\ \ " +The valued option +.q EDITOR +defines the pathname of the text editor to be used in the +.b edit +command and ~e. If not defined, a standard editor is used. +.ip "\fBPAGER\fP\ \ " +Pathname of the program to use for paginating output when +it exceeds \fIcrt\fP lines. +A default paginator is used if this option is not defined. +.ip "\fBSHELL\fP\ \ " +The valued option +.q SHELL +gives the path name of your shell. This shell is used for the +.b ! +command and ~! escape. In addition, this shell expands +file names with shell metacharacters like * and ? in them. +.ip "\fBVISUAL\fP\ \ " +The valued option +.q VISUAL +defines the pathname of the screen editor to be used in the +.b visual +command +and ~v escape. A standard screen editor is used if you do not define one. +.ip "\fBappend\fP\ \ " +The +.q append +option is binary and +causes messages saved in +.i mbox +to be appended to the end rather than prepended. +Normally, \fIMail\fP will put messages in \fImbox\fP +in the same order that the system puts messages in your system mailbox. +By setting +.q append, +you are requesting that +.i mbox +be appended to regardless. It is in any event quicker to append. +.ip "\fBask\fP\ \ " +.q "Ask" +is a binary option which +causes +.i Mail +to prompt you for the subject of each message you send. +If you respond with simply a newline, no subject field will be sent. +.ip "\fBaskcc\fP\ \ " +.q Askcc +is a binary option which +causes you to be prompted for additional carbon copy recipients at the +end of each message. Responding with a newline shows your +satisfaction with the current list. +.ip "\fBautoprint\fP\ \ " +.q Autoprint +is a binary option which +causes the +.b delete +command to behave like +.b dp +\*- thus, after deleting a message, the next one will be typed +automatically. This is useful when quickly scanning and deleting +messages in your mailbox. +.ip "\fBcrt\fP \ \ " +The valued option +.I crt +is used as a threshold to determine how long a message must +be before +.b PAGER +is used to read it. +.ip "\fBdebug\fP \ \ " +The binary option +.q debug +causes debugging information to be displayed. Use of this +option is the same as using the \fB\-d\fP command line flag. +.ip "\fBdot\fP\ \ " +.q Dot +is a binary option which, if set, causes +.i Mail +to interpret a period alone on a line as the terminator +of the message you are sending. +.ip "\fBescape\fP\ \ " +To allow you to change the escape character used when sending +mail, you can set the valued option +.q escape. +Only the first character of the +.q escape +option is used, and it must be doubled if it is to appear as +the first character of a line of your message. If you change your escape +character, then ~ loses all its special meaning, and need no longer be doubled +at the beginning of a line. +.ip "\fBfolder\fP\ \ " +The name of the directory to use for storing folders of messages. +If this name begins with a `/' +.i Mail +considers it to be an absolute pathname; otherwise, the folder directory +is found relative to your home directory. +.ip "\fBhold\fP\ \ " +The binary option +.q hold +causes messages that have been read but not manually dealt with +to be held in the system mailbox. This prevents such messages from +being automatically swept into your \fImbox\fP file. +.ip "\fBignore\fP\ \ " +The binary option +.q ignore +causes \s-2RUBOUT\s0 characters from your terminal to be ignored and echoed +as @'s while you are sending mail. \s-2RUBOUT\s0 characters retain their +original meaning in +.i Mail +command mode. +Setting the +.q ignore +option is equivalent to supplying the +.b \-i +flag on the command line as described in section 6. +.ip "\fBignoreeof\fP\ \ " +An option related to +.q dot +is +.q ignoreeof +which makes +.i Mail +refuse to accept a control\-d as the end of a message. +.q Ignoreeof +also applies to +.i Mail +command mode. +.ip "\fBkeep\fP\ \ " +The +.q keep +option causes +.i Mail +to truncate your system mailbox instead of deleting it when it +is empty. This is useful if you elect to protect your mailbox, which +you would do with the shell command: +.(l +chmod 600 /usr/spool/mail/yourname +.)l +where +.i yourname +is your login name. If you do not do this, anyone can probably read +your mail, although people usually don't. +.ip "\fBkeepsave\fP\ \ " +When you +.b save +a message, +.i Mail +usually discards it when you +.b quit . +To retain all saved messages, set the +.q keepsave +option. +.ip "\fBmetoo\fP\ \ " +When sending mail to an alias, +.i Mail +makes sure that if you are included in the alias, that mail will not +be sent to you. This is useful if a single alias is being used by +all members of the group. If however, you wish to receive a copy of +all the messages you send to the alias, you can set the binary option +.q metoo. +.ip "\fBnoheader\fP\ \ " +The binary option +.q noheader +suppresses the printing of the version and headers when +.i Mail +is first invoked. Setting this option is the same as using +.b \-N +on the command line. +.ip "\fBnosave\fP\ \ " +Normally, +when you abort a message with two \s-2RUBOUTs\s0, +.i Mail +copies the partial letter to the file +.q dead.letter +in your home directory. Setting the binary option +.q nosave +prevents this. +.ip "\fBReplyall\fP\ \ " +Reverses the sense of +.i reply +and +.i Reply +commands. +.ip "\fBquiet\fP\ \ " +The binary option +.q quiet +suppresses the printing of the version when +.i Mail +is first invoked, +as well as printing the for example +.q "Message 4:" +from the +.b type +command. +.ip "\fBrecord\fP\ \ " +If you love to keep records, then the +valued option +.q record +can be set to the name of a file to save your outgoing mail. +Each new message you send is appended to the end of the file. +.ip "\fBscreen\fP\ \ " +When +.i Mail +initially prints the message headers, it determines the number to +print by looking at the speed of your terminal. The faster your +terminal, the more it prints. +The valued option +.q screen +overrides this calculation and +specifies how many message headers you want printed. +This number is also used for scrolling with the +.b z +command. +.ip "\fBsendmail\fP\ \ " +To use an alternate mail delivery system, set the +.q sendmail +option to the full pathname of the program to use. Note: this is not +for everyone! Most people should use the default delivery system. +.ip "\fBtoplines\fP\ \ " +The valued option +.q toplines +defines the number of lines that the +.q top +command will print out instead of the default five lines. +.ip "\fBverbose\fP\ \ " +The binary option "verbose" causes +.i Mail +to invoke sendmail with the +.b \-v +flag, which causes it to go into verbose mode and announce expansion +of aliases, etc. Setting the "verbose" option is equivalent to +invoking +.i Mail +with the +.b \-v +flag as described in section 6. diff --git a/usr.bin/mail/USD.doc/mail6.nr b/usr.bin/mail/USD.doc/mail6.nr new file mode 100644 index 0000000..e016234 --- /dev/null +++ b/usr.bin/mail/USD.doc/mail6.nr @@ -0,0 +1,125 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

Not generally useful, since +/usr/lib/Mail.rc is usually empty. +.ip "\-s string" +Used for sending mail. +.i String +is used as the subject of the message being composed. If +.i string +contains blanks, you must surround it with quote marks. +.ip "\-u name" +Read +.i names's +mail instead of your own. Unwitting others often neglect to protect +their mailboxes, but discretion is advised. Essentially, +.b "\-u user" +is a shorthand way of doing +.b "\-f /usr/spool/mail/user". +.ip "\-v" +Use the +.b \-v +flag when invoking sendmail. This feature may also be enabled +by setting the the option "verbose". +.pp +The following command line flags are also recognized, but are +intended for use by programs invoking +.i Mail +and not for people. +.ip "\-T file" +Arrange to print on +.i file +the contents of the +.i article-id +fields of all messages that were either read or deleted. +.b \-T +is for the +.i readnews +program and should NOT be used for reading your mail. +.ip "\-h number" +Pass on hop count information. +.i Mail +will take the number, increment it, and pass it with +.b \-h +to the mail delivery system. +.b \-h +only has effect when sending mail and is used for network mail +forwarding. +.ip "\-r name" +Used for network mail forwarding: interpret +.i name +as the sender of the message. The +.i name +and +.b \-r +are simply sent along to the mail delivery system. Also, +.i Mail +will wait for the message to be sent and return the exit status. +Also restricts formatting of message. +.pp +Note that +.b \-h +and +.b \-r , +which are for network mail forwarding, are not used in practice +since mail forwarding is now handled separately. They may +disappear soon. diff --git a/usr.bin/mail/USD.doc/mail7.nr b/usr.bin/mail/USD.doc/mail7.nr new file mode 100644 index 0000000..0b2590b --- /dev/null +++ b/usr.bin/mail/USD.doc/mail7.nr @@ -0,0 +1,107 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

A possible +.i ctime +format date is: +.(l +Tue Dec 1 10:58:23 1981 +.)l +The +.i ctime +date may be optionally followed by a single space and a +time zone indication, which +should be three capital letters, such as PDT. +.pp +Following the +.i from +line are zero or more +.i "header field" +lines. +Each header field line is of the form: +.(l +name: information +.)l +.i Name +can be anything, but only certain header fields are recognized as +having any meaning. The recognized header fields are: +.i article-id , +.i bcc , +.i cc , +.i from , +.i reply-to , +.i sender , +.i subject , +and +.i to . +Other header fields are also significant to other systems; see, +for example, the current Arpanet message standard for much more +information on this topic. +A header field can be continued onto following lines by making the +first character on the following line a space or tab character. +.pp +If any headers are present, they must be followed by a blank line. +The part that follows is called the +.i body +of the message, and must be ASCII text, not containing null characters. +Each line in the message body must be no longer than 512 characters and +terminated with an ASCII newline character. +If binary data must be passed through the mail system, it is suggested +that this data be encoded in a system which encodes six bits into +a printable character (i.e.: uuencode). +For example, one could use the upper and lower case letters, the digits, +and the characters comma and period to make up the 64 characters. +Then, one can send a 16-bit binary number +as three characters. These characters should be packed into lines, +preferably lines about 70 characters long as long lines are transmitted +more efficiently. +.pp +The message delivery system always adds a blank line to the end of +each message. This blank line must not be deleted. +.pp +The UUCP message delivery system sometimes adds a blank line to +the end of a message each time it is forwarded through a machine. +.pp +It should be noted that some network transport protocols enforce +limits to the lengths of messages. diff --git a/usr.bin/mail/USD.doc/mail8.nr b/usr.bin/mail/USD.doc/mail8.nr new file mode 100644 index 0000000..e8e056b --- /dev/null +++ b/usr.bin/mail/USD.doc/mail8.nr @@ -0,0 +1,75 @@ +.\" Copyright (c) 1980, 1993 +.\" The Regents of the University of California.

reminiscent of +.Xr \&ed 1 +with lines replaced by messages. +.Pp +.Bl -tag -width flag +.It Fl v +Verbose mode. +The details of +delivery are displayed on the user's terminal. +.It Fl i +Ignore tty interrupt signals. +This is +particularly useful when using +.Nm mail +on noisy phone lines. +.It Fl I +Forces mail to run in interactive mode even when +input isn't a terminal. +In particular, the +.Sq Ic \&~ +special +character when sending mail is only active in interactive mode. +.It Fl n +Inhibits reading +.Pa /usr/share/misc/Mail.rc +upon startup. +.It Fl N +Inhibits the initial display of message headers +when reading mail or editing a mail folder. +.It Fl s +Specify subject on command line +(only the first argument after the +.Fl s +flag is used as a subject; be careful to quote subjects +containing spaces.) +.It Fl c +Send carbon copies to +.Ar list +of users. +.It Fl b +Send blind carbon copies to +.Ar list . +List should be a comma-separated list of names. +.It Fl f +Read in the contents of your +.Ar mbox +(or the specified file) +for processing; when you +.Ar quit , +.Nm mail +writes undeleted messages back to this file. +.It Fl u +Is equivalent to: +.Pp +.Dl mail -f /var/spool/mail/user +.El +.Ss Sending mail +To send a message to one or more people, +.Nm mail +can be invoked with arguments which are the names of people to +whom the mail will be sent. +You are then expected to type in +your message, followed +by an +.Sq Li control\-D +at the beginning of a line. +The section below +.Ar Replying to or originating mail , +describes some features of +.Nm mail +available to help you compose your letter. +.Pp +.Ss Reading mail +In normal usage +.Nm mail +is given no arguments and checks your mail out of the +post office, then +prints out a one line header of each message found. +The current message is initially the first message (numbered 1) +and can be printed using the +.Ic print +command (which can be abbreviated +.Ql Ic p ) . +You can move among the messages much as you move between lines in +.Xr \&ed 1 , +with the commands +.Ql Ic \&+ +and +.Ql Ic \&\- +moving backwards and forwards, and +simple numbers. +.Pp +.Ss Disposing of mail. +After examining a message you can +.Ic delete +.Ql Ic d ) +the message or +.Ic reply +.Ql Ic r ) +to it. +Deletion causes the +.Nm mail +program to forget about the message. +This is not irreversible; the message can be +.Ic undeleted +.Ql Ic u ) +by giving its number, or the +.Nm mail +session can be aborted by giving the +.Ic exit +.Ql Ic x ) +command. +Deleted messages will, however, usually disappear never to be seen again. +.Pp +.Ss Specifying messages +Commands such as +.Ic print +and +.Ic delete +can be given a list of message numbers as arguments to apply +to a number of messages at once. +Thus +.Dq Li delete 1 2 +deletes messages 1 and 2, while +.Dq Li delete 1\-5 +deletes messages 1 through 5. +The special name +.Ql Li \&* +addresses all messages, and +.Ql Li \&$ +addresses +the last message; thus the command +.Ic top +which prints the first few lines of a message could be used in +.Dq Li top \&* +to print the first few lines of all messages. +.Pp +.Ss Replying to or originating mail. +You can use the +.Ic reply +command to +set up a response to a message, sending it back to the +person who it was from. +Text you then type in, up to an end-of-file, +defines the contents of the message. +While you are composing a message, +.Nm mail +treats lines beginning with the character +.Ql Ic \&~ +specially. +For instance, typing +.Ql Ic \&~m +(alone on a line) will place a copy +of the current message into the response right shifting it by a tabstop +(see +.Em indentprefix +variable, below). +Other escapes will set up subject fields, add and delete recipients +to the message and allow you to escape to an editor to revise the +message or to a shell to run some commands. +(These options +are given in the summary below.) +.Pp +.Ss Ending a mail processing session. +You can end a +.Nm mail +session with the +.Ic quit +.Ql Ic q ) +command. +Messages which have been examined go to your +.Ar mbox +file unless they have been deleted in which case they are discarded. +Unexamined messages go back to the post office. +(See the +.Fl f +option above). +.Pp +.Ss Personal and systemwide distribution lists. +It is also possible to create a personal distribution lists so that, +for instance, you can send mail to +.Dq Li cohorts +and have it go +to a group of people. +Such lists can be defined by placing a line like +.Pp +.Dl alias cohorts bill ozalp jkf mark kridle@ucbcory +.Pp +in the file +.Pa \&.mailrc +in your home directory. +The current list of such aliases can be displayed with the +.Ic alias +command in +.Nm mail . +System wide distribution lists can be created by editing +.Pa /etc/aliases , +see +.Xr aliases 5 +and +.Xr sendmail 8 ; +these are kept in a different syntax. +In mail you send, personal aliases will be expanded in mail sent +to others so that they will be able to +.Ic reply +to the recipients. +System wide +.Ic aliases +are not expanded when the mail is sent, +but any reply returned to the machine will have the system wide +alias expanded as all mail goes through +.Xr sendmail . +.Pp +.Ss Network mail (ARPA, UUCP, Berknet) +See +.Xr mailaddr 7 +for a description of network addresses. +.Pp +.Nm Mail +has a number of options which can be set in the +.Pa .mailrc +file to alter its behavior; thus +.Dq Li set askcc +enables the +.Ar askcc +feature. +(These options are summarized below.) +.Sh SUMMARY +(Adapted from the `Mail Reference Manual') +.Pp +Each command is typed on a line by itself, and may take arguments +following the command word. +The command need not be typed in its +entirety \- the first command which matches the typed prefix is used. +For commands which take message lists as arguments, if no message +list is given, then the next message forward which satisfies the +command's requirements is used. +If there are no messages forward of +the current message, the search proceeds backwards, and if there are no +good messages at all, +.Nm mail +types +.Dq Li No applicable messages +and +aborts the command. +.Bl -tag -width delete +.It Ic \&\- +Print out the preceding message. +If given a numeric +argument +.Ar n , +goes to the +.Ar n Ns 'th +previous message and prints it. +.It Ic \&? +Prints a brief summary of commands. +.It Ic \&! +Executes the shell +(see +.Xr sh 1 +and +.Xr csh 1 ) +command which follows. +.It Ic Print +.Pq Ic P +Like +.Ic print +but also prints out ignored header fields. +See also +.Ic print , +.Ic ignore +and +.Ic retain . +.It Ic Reply +.Pq Ic R +Reply to originator. +Does not reply to other +recipients of the original message. +.It Ic Type +.Pq Ic T +Identical to the +.Ic Print +command. +.It Ic alias +.Pq Ic a +With no arguments, prints out all currently-defined aliases. +With one +argument, prints out that alias. +With more than one argument, creates +a new alias or changes an old one. +.It Ic alternates +.Pq Ic alt +The +.Ic alternates +command is useful if you have accounts on several machines. +It can be used to inform +.Nm mail +that the listed addresses are really you. +When you +.Ic reply +to messages, +.Nm mail +will not send a copy of the message to any of the addresses +listed on the +.Ic alternates +list. +If the +.Ic alternates +command is given with no argument, the current set of alternate +names is displayed. +.It Ic chdir +.Pq Ic c +Changes the user's working directory to that specified, if given. +If +no directory is given, then changes to the user's login directory. +.It Ic copy +.Pq Ic co +The +.Ic copy +command does the same thing that +.Ic save +does, except that it does not mark the messages it +is used on for deletion when you quit. +.It Ic delete +.Pq Ic d +Takes a list of messages as argument and marks them all as deleted. +Deleted messages will not be saved in +.Ar mbox , +nor will they be available for most other commands. +.It Ic dp +(also +.Ic dt ) +Deletes the current message and prints the next message. +If there is no next message, +.Nm mail +says +.Dq Li "at EOF" . +.It Ic edit +.Pq Ic e +Takes a list of messages and points the text editor at each one in +turn. +On return from the editor, the message is read back in. +.It Ic exit +.Pf ( Ic ex +or +.Ic x ) +Effects an immediate return to the Shell without +modifying the user's system mailbox, his +.Ar mbox +file, or his edit file in +.Fl f . +.It Ic file +.Pq Ic fi +The same as +.Ic folder . +.It Ic folders +List the names of the folders in your folder directory. +.It Ic folder +.Pq Ic fo +The +.Ic folder +command switches to a new mail file or folder. +With no +arguments, it tells you which file you are currently reading. +If you give it an argument, it will write out changes (such +as deletions) you have made in the current file and read in +the new file. +Some special conventions are recognized for +the name. +# means the previous file, % means your system +mailbox, %user means user's system mailbox, & means +your +.Ar mbox +file, and +\&+\&folder means a file in your folder +directory. +.It Ic from +.Pq Ic f +Takes a list of messages and prints their message headers. +.It Ic headers +.Pq Ic h +Lists the current range of headers, which is an 18\-message group. +If +a +.Ql \&+ +argument is given, then the next 18\-message group is printed, and if +a +.Ql \&\- +argument is given, the previous 18\-message group is printed. +.It Ic help +A synonym for +.Ic \&? +.It Ic hold +.Pf ( Ic ho , +also +.Ic preserve ) +Takes a message list and marks each +message therein to be saved in the +user's system mailbox instead of in +.Ar mbox . +Does not override the +.Ic delete +command. +.It Ic ignore +Add the list of header fields named to the +.Ar ignored list . +Header fields in the ignore list are not printed +on your terminal when you print a message. +This +command is very handy for suppression of certain machine-generated +header fields. +The +.Ic Type +and +.Ic Print +commands can be used to print a message in its entirety, including +ignored fields. +If +.Ic ignore +is executed with no arguments, it lists the current set of +ignored fields. +.It Ic mail +.Pq Ic m +Takes as argument login names and distribution group names and sends +mail to those people. +.It Ic mbox +Indicate that a list of messages be sent to +.Ic mbox +in your home directory when you quit. +This is the default +action for messages if you do +.Em not +have the +.Ic hold +option set. +.It Ic next +.Pq Ic n +like +.Ic \&+ +or +.Tn CR ) +Goes to the next message in sequence and types it. +With an argument list, types the next matching message. +.It Ic preserve +.Pq Ic pre +A synonym for +.Ic hold . +.It Ic print +.Pq Ic p +Takes a message list and types out each message on the user's terminal. +.It Ic quit +.Pq Ic q +Terminates the session, saving all undeleted, unsaved messages in +the user's +.Ar mbox +file in his login directory, preserving all messages marked with +.Ic hold +or +.Ic preserve +or never referenced +in his system mailbox, and removing all other messages from his system +mailbox. +If new mail has arrived during the session, the message +.Dq Li "You have new mail" +is given. +If given while editing a +mailbox file with the +.Fl f +flag, then the edit file is rewritten. +A return to the Shell is +effected, unless the rewrite of edit file fails, in which case the user +can escape with the +.Ic exit +command. +.It Ic reply +.Pq Ic r +Takes a message list and sends mail to the sender and all +recipients of the specified message. +The default message must not be deleted. +.It Ic respond +A synonym for +.Ic reply . +.It Ic retain +Add the list of header fields named to the +.Ar retained list +Only the header fields in the retain list +are shown on your terminal when you print a message. +All other header fields are suppressed. +The +.Ic Type +and +.Ic Print +commands can be used to print a message in its entirety. +If +.Ic retain +is executed with no arguments, it lists the current set of +retained fields. +.It Ic save +.Pq Ic s +Takes a message list and a filename and appends each message in +turn to the end of the file. +The filename in quotes, followed by the line +count and character count is echoed on the user's terminal. +.It Ic set +.Pq Ic se +With no arguments, prints all variable values. +Otherwise, sets +option. +Arguments are of the form +.Ar option=value +(no space before or after =) or +.Ar option . +Quotation marks may be placed around any part of the assignment statement to +quote blanks or tabs, i.e. +.Dq Li "set indentprefix=\*q->\*q" +.It Ic saveignore +.Ic Saveignore +is to +.Ic save +what +.Ic ignore +is to +.Ic print +and +.Ic type . +Header fields thus marked are filtered out when +saving a message by +.Ic save +or when automatically saving to +.Ar mbox . +.It Ic saveretain +.Ic Saveretain +is to +.Ic save +what +.Ic retain +is to +.Ic print +and +.Ic type . +Header fields thus marked are the only ones saved +with a message when saving by +.Ic save +or when automatically saving to +.Ar mbox . +.Ic Saveretain +overrides +.Ic saveignore . +.It Ic shell +.Pq Ic sh +Invokes an interactive version of the shell. +.It Ic size +Takes a message list and prints out the size in characters of each +message. +.It Ic source +The +.Ic source +command reads +commands from a file. +.It Ic top +Takes a message list and prints the top few lines of each. +The number of +lines printed is controlled by the variable +.Ic toplines +and defaults to five. +.It Ic type +.Pq Ic t +A synonym for +.Ic print . +.It Ic unalias +Takes a list of names defined by +.Ic alias +commands and discards the remembered groups of users. +The group names +no longer have any significance. +.It Ic undelete +.Pq Ic u +Takes a message list and marks each message as +.Ic not +being deleted. +.It Ic unread +.Pq Ic U +Takes a message list and marks each message as +.Ic not +having been read. +.It Ic unset +Takes a list of option names and discards their remembered values; +the inverse of +.Ic set . +.It Ic visual +.Pq Ic v +Takes a message list and invokes the display editor on each message. +.It Ic write +.Pq Ic w +Similar to +.Ic save , +except that +.Ic only +the message body +.Pq Ar without +the header) is saved. +Extremely useful for such tasks as sending and receiving source +program text over the message system. +.It Ic xit +.Pq Ic x +A synonym for +.Ic exit . +.It Ic z +.Nm Mail +presents message headers in windowfuls as described under the +.Ic headers +command. +You can move +.Nm mail Ns 's +attention forward to the next window with the +.Ic \&z +command. +Also, you can move to the previous window by using +.Ic \&z\&\- . +.El +.Ss Tilde/Escapes +.Pp +Here is a summary of the tilde escapes, +which are used when composing messages to perform +special functions. +Tilde escapes are only recognized at the beginning +of lines. +The name +.Dq Em tilde\ escape +is somewhat of a misnomer since the actual escape character can be set +by the option +.Ic escape . +.Bl -tag -width Ds +.It Ic \&~! Ns Ar command +Execute the indicated shell command, then return to the message. +.It Ic \&~b Ns Ar name ... +Add the given names to the list of carbon copy recipients but do not make +the names visible in the Cc: line ("blind" carbon copy). +.It Ic \&~c Ns Ar name ... +Add the given names to the list of carbon copy recipients. +.It Ic \&~d +Read the file +.Dq Pa dead.letter +from your home directory into the message. +.It Ic \&~e +Invoke the text editor on the message collected so far. +After the +editing session is finished, you may continue appending text to the +message. +.It Ic \&~f Ns Ar messages +Read the named messages into the message being sent. +If no messages are specified, read in the current message. +Message headers currently being ignored (by the +.Ic ignore +or +.Ic retain +command) are not included. +.It Ic \&~F Ns Ar messages +Identical to +.Ic \&~f , +except all message headers are included. +.It Ic \&~h +Edit the message header fields by typing each one in turn and allowing +the user to append text to the end or modify the field by using the +current terminal erase and kill characters. +.It Ic \&~m Ns Ar messages +Read the named messages into the message being sent, indented by a +tab or by the value of +.Ar indentprefix . +If no messages are specified, +read the current message. +Message headers currently being ignored (by the +.Ic ignore +or +.Ic retain +command) are not included. +.It Ic \&~M Ns Ar messages +Identical to +.Ic \&~m , +except all message headers are included. +.It Ic \&~p +Print out the message collected so far, prefaced by the message header +fields. +.It Ic \&~q +Abort the message being sent, copying the message to +.Dq Pa dead.letter +in your home directory if +.Ic save +is set. +.It Ic \&~r Ns Ar filename +Read the named file into the message. +.It Ic \&~s Ns Ar string +Cause the named string to become the current subject field. +.It Ic \&~\&t Ns Ar name ... +Add the given names to the direct recipient list. +.It Ic \&~\&v +Invoke an alternate editor (defined by the +.Ev VISUAL +option) on the +message collected so far. +Usually, the alternate editor will be a +screen editor. +After you quit the editor, you may resume appending +text to the end of your message. +.It Ic \&~w Ns Ar filename +Write the message onto the named file. +.It Ic \&~\&| Ns Ar command +Pipe the message through the command as a filter. +If the command gives +no output or terminates abnormally, retain the original text of the +message. +The command +.Xr fmt 1 +is often used as +.Ic command +to rejustify the message. +.It Ic \&~: Ns Ar mail-command +Execute the given mail command. +Not all commands, however, are allowed. +.It Ic \&~~ Ns Ar string +Insert the string of text in the message prefaced by a single ~. +If +you have changed the escape character, then you should double +that character in order to send it. +.El +.Ss Mail Options +Options are controlled via +.Ic set +and +.Ic unset +commands. +Options may be either binary, in which case it is only +significant to see whether they are set or not; or string, in which +case the actual value is of interest. +The binary options include the following: +.Bl -tag -width append +.It Ar append +Causes messages saved in +.Ar mbox +to be appended to the end rather than prepended. +This should always be set (perhaps in +.Pa /usr/share/misc/Mail.rc ) . +.It Ar ask +Causes +.Nm mail +to prompt you for the subject of each message you send. +If +you respond with simply a newline, no subject field will be sent. +.It Ar askcc +Causes you to be prompted for additional carbon copy recipients at the +end of each message. +Responding with a newline indicates your +satisfaction with the current list. +.It Ar autoprint +Causes the +.Ic delete +command to behave like +.Ic dp +\- thus, after deleting a message, the next one will be typed +automatically. +.It Ar debug +Setting the binary option +.Ar debug +is the same as specifying +.Fl d +on the command line and causes +.Nm mail +to output all sorts of information useful for debugging +.Nm mail . +.It Ar dot +The binary option +.Ar dot +causes +.Nm mail +to interpret a period alone on a line as the terminator +of a message you are sending. +.It Ar hold +This option is used to hold messages in the system mailbox +by default. +.It Ar ignore +Causes interrupt signals from your terminal to be ignored and echoed as +@'s. +.It Ar ignoreeof +An option related to +.Ar dot +is +.Ar ignoreeof +which makes +.Nm mail +refuse to accept a control-d as the end of a message. +.Ar Ignoreeof +also applies to +.Nm mail +command mode. +.It Ar metoo +Usually, when a group is expanded that contains the sender, the sender +is removed from the expansion. +Setting this option causes the sender +to be included in the group. +.It Ar noheader +Setting the option +.Ar noheader +is the same as giving the +.Fl N +flag on the command line. +.It Ar nosave +Normally, when you abort a message with two +.Tn RUBOUT +(erase or delete) +.Nm mail +copies the partial letter to the file +.Dq Pa dead.letter +in your home directory. +Setting the binary option +.Ar nosave +prevents this. +.It Ar Replyall +Reverses the sense of +.Ic reply +and +.Ic Reply +commands. +.It Ar quiet +Suppresses the printing of the version when first invoked. +.It Ar searchheaders +If this option is set, then a message-list specifier in the form ``/x:y'' +will expand to all messages containing the substring ``y'' in the header +field ``x''. The string search is case insensitive. +.It Ar verbose +Setting the option +.Ar verbose +is the same as using the +.Fl v +flag on the command line. +When mail runs in verbose mode, +the actual delivery of messages is displayed on the user's +terminal. +.El +.Ss Option String Values +.Bl -tag -width Va +.It Ev EDITOR +Pathname of the text editor to use in the +.Ic edit +command and +.Ic \&~e +escape. +If not defined, then a default editor is used. +.It Ev LISTER +Pathname of the directory lister to use in the +.Ic folders +command. +Default is +.Pa /bin/ls . +.It Ev PAGER +Pathname of the program to use in the +.Ic more +command or when +.Ic crt +variable is set. +The default paginator +.Xr more 1 +is used if this option is not defined. +.It Ev SHELL +Pathname of the shell to use in the +.Ic \&! +command and the +.Ic \&~! +escape. +A default shell is used if this option is +not defined. +.It Ev VISUAL +Pathname of the text editor to use in the +.Ic visual +command and +.Ic \&~v +escape. +.It Va crt +The valued option +.Va crt +is used as a threshold to determine how long a message must +be before +.Ev PAGER +is used to read it. +If +.Va crt +is set without a value, +then the height of the terminal screen stored in the system +is used to compute the threshold (see +.Xr stty 1 ) . +.It Ar escape +If defined, the first character of this option gives the character to +use in the place of ~ to denote escapes. +.It Ar folder +The name of the directory to use for storing folders of +messages. +If this name begins with a `/', +.Nm mail +considers it to be an absolute pathname; otherwise, the +folder directory is found relative to your home directory. +.It Ev MBOX +The name of the +.Ar mbox +file. +It can be the name of a folder. +The default is +.Dq Li mbox +in the user's home directory. +.It Ar record +If defined, gives the pathname of the file used to record all outgoing +mail. +If not defined, then outgoing mail is not so saved. +.It Ar indentprefix +String used by the ``~m'' tilde escape for indenting messages, in place of +the normal tab character (^I). +Be sure to quote the value if it contains +spaces or tabs. +.It Ar toplines +If defined, gives the number of lines of a message to be printed out +with the +.Ic top +command; normally, the first five lines are printed. +.El +.Sh ENVIRONMENT +.Nm Mail +utilizes the +.Ev HOME +and +.Ev USER +environment variables. +.Sh FILES +.Bl -tag -width /usr/share/misc/Mail.help* -compact +.It Pa /var/spool/mail/* +Post office. +.It ~/mbox +User's old mail. +.It ~/.mailrc +File giving initial mail commands. +.It Pa /tmp/R* +Temporary files. +.It Pa /usr/share/misc/Mail.help* +Help files. +.It Pa /usr/share/misc/Mail.rc +System initialization file. +.El +.Sh SEE ALSO +.Xr fmt 1 , +.Xr newaliases 1 , +.Xr vacation 1 , +.Xr aliases 5 , +.Xr mailaddr 7 , +.Xr sendmail 8 +and +.Rs +.%T "The Mail Reference Manual" . +.Re +.Sh HISTORY +A +.Nm mail +command +appeared in +.At v6 . +This man page is derived from +.%T "The Mail Reference Manual" +originally written by Kurt Shoens. +.Sh BUGS +There are some flags that are not documented here. +Most are +not useful to the general user. +.Pp +Usually, +.Nm mail +is just a link to +.Nm Mail , +which can be confusing. diff --git a/usr.bin/mail/main.c b/usr.bin/mail/main.c new file mode 100644 index 0000000..1e1579b --- /dev/null +++ b/usr.bin/mail/main.c @@ -0,0 +1,296 @@ +/* + * Copyright (c) 1980, 1993 + * The Regents of the University of California.

It +uses +.Xr termcap 3 +so it can run on a variety of terminals. There is even limited support +for hardcopy terminals. (On a hardcopy terminal, lines which should be +printed at the top of the screen are prefixed with an up-arrow.) +.Ar File +may be a single dash (``-''), implying stdin. +.Sh OPTIONS +Command line options are described below. +Options are also taken from the environment variable +.Ev MORE +(make sure to precede them with a dash (``-'')) but command +line options will override them. +.Bl -tag -width flag +.It Fl c +Normally, +.Nm more +will repaint the screen by scrolling from the bottom of the screen. +If the +.Fl c +option is set, when +.Nm more +needs to change the entire display, it will paint from the top line down. +.It Fl e +Normally, if displaying a single file, +.Nm more +exits as soon as it reaches end-of-file. The +.Fl e +option tells more to +exit if it reaches end-of-file twice without an intervening operation. +If the file is shorter than a single screen +.Nm more +will exit at end-of-file regardless. +.It Fl i +The +.Fl i +option causes searches to ignore case; that is, +uppercase and lowercase are considered identical. +.It Fl n +The +.Fl n +flag suppresses line numbers. +The default (to use line numbers) may cause +.Nm more +to run more slowly in some cases, especially with a very large input file. +Suppressing line numbers with the +.Fl n +flag will avoid this problem. +Using line numbers means: the line number will be displayed in the +.Cm = +command, and the +.Cm v +command will pass the current line number to the editor. +.It Fl s +The +.Fl s +option causes +consecutive blank lines to be squeezed into a single blank line. +.It Fl t +The +.Fl t +option, followed immediately by a tag, will edit the file +containing that tag. For more information, see the +.Xr ctags 1 +command. +.It Fl u +By default, +.Nm more +treats backspaces and +.Dv CR-LF +sequences specially. Backspaces which appear +adjacent to an underscore character are displayed as underlined text. +Backspaces which appear between two identical characters are displayed +as emboldened text. +.Dv CR-LF +sequences are compressed to a single linefeed +character. The +.Fl u +option causes backspaces to always be displayed as +control characters, i.e. as the two character sequence ``^H'', and +.Dv CR-LF +to be left alone. +.It Fl x +The +.Fl x +option sets tab stops every +.Ar N +positions. The default for +.Ar N +is 8. +.It Fl / +The +.Fl / +option specifies a string that will be searched for before +each file is displayed. +.Sh COMMANDS +Interactive commands for +.Nm more +are based on +.Xr vi 1 . +Some commands may be preceded by a decimal number, called N in the +descriptions below. +In the following descriptions, ^X means control-X. +.Pp +.Bl -tag -width Ic +.It Ic h +Help: display a summary of these commands. +If you forget all the other commands, remember this one. +.It Xo +.Ic SPACE +.No or +.Ic f +.No or +.Ic \&^F +.Xc +Scroll forward N lines, default one window. +If N is more than the screen size, only the final screenful is displayed. +.It Ic b No or Ic \&^B +Scroll backward N lines, default one window (see option -z below). +If N is more than the screen size, only the final screenful is displayed. +.It Ic j No or Ic RETURN +Scroll forward N lines, default 1. +The entire N lines are displayed, even if N is more than the screen size. +.It Ic k +Scroll backward N lines, default 1. +The entire N lines are displayed, even if N is more than the screen size. +.It Ic d No or Ic \&^D +Scroll forward N lines, default one half of the screen size. +If N is specified, it becomes the new default for +subsequent d and u commands. +.It Ic u No or Ic \&^U +Scroll backward N lines, default one half of the screen size. +If N is specified, it becomes the new default for +subsequent d and u commands. +.It Ic g +Go to line N in the file, default 1 (beginning of file). +.It Ic G +Go to line N in the file, default the end of the file. +.It Ic p No or Ic \&% +Go to a position N percent into the file.

If label and file names conflict, +it is assumed to be a label. +These may be used together to update specific files +using specific commands. +.Pp +Options specific to the second SYNOPSIS form: +.Pp +.Bl -tag -width Fl c +.It Fl c +Forces +.Nm rdist +to interpret the remaining arguments as a small +.Ar distfile . +.Pp +The equivalent distfile is as follows. +.Pp +.Bd -filled -offset indent -compact +.Pq Ar name ... +.Li -> +.Op Ar login@ +.Ar host +.Bd -filled -offset indent -compact +.Li install +.Op Ar dest ; +.Ed +.Ed +.El +.Pp +Options common to both forms: +.Pp +.Bl -tag -width Ic +.It Fl b +Binary comparison. Perform a binary comparison and update files if they differ +rather than comparing dates and sizes. +.It Fl d Ar var=value +Define +.Ar var +to have +.Ar value . +The +.Fl d +option is used to define or override variable definitions in the +.Ar distfile . +.Ar Value +can be the empty string, one name, or a list of names surrounded by +parentheses and separated by tabs and/or spaces. +.It Fl h +Follow symbolic links. Copy the file that the link points to rather than the +link itself. +.It Fl i +Ignore unresolved links. +.Nm Rdist +will normally try to maintain the link structure of files being transferred +and warn the user if all the links cannot be found. +.It Fl m Ar host +Limit which machines are to be updated. Multiple +.Fl m +arguments can be given to limit updates to a subset of the hosts listed in the +.Ar distfile . +.It Fl n +Print the commands without executing them. This option is +useful for debugging +.Ar distfile . +.It Fl q +Quiet mode. Files that are being modified are normally +printed on standard output. The +.Fl q +option suppresses this. +.It Fl R +Remove extraneous files. If a directory is being updated, any files that exist +on the remote host that do not exist in the master directory are removed. +This is useful for maintaining truly identical copies of directories. +.It Fl v +Verify that the files are up to date on all the hosts. Any files +that are out of date will be displayed but no files will be changed +nor any mail sent. +.It Fl w +Whole mode. The whole file name is appended to the destination directory +name. Normally, only the last component of a name is used when renaming files. +This will preserve the directory structure of the files being +copied instead of flattening the directory structure. For example, +renaming a list of files such as ( dir1/f1 dir2/f2 ) to dir3 would create +files dir3/dir1/f1 and dir3/dir2/f2 instead of dir3/f1 and dir3/f2. +.It Fl y +Younger mode. Files are normally updated if their +.Ar mtime +and +.Ar size +(see +.Xr stat 2 ) +disagree. The +.Fl y +option causes +.Nm rdist +not to update files that are younger than the master copy. +This can be used +to prevent newer copies on other hosts from being replaced. +A warning message is printed for files which are newer than the master copy. +.El +.Pp +.Ar Distfile +contains a sequence of entries that specify the files +to be copied, the destination hosts, and what operations to perform +to do the updating. Each entry has one of the following formats. +.Pp +.Bd -literal -offset indent -compact + `=' +[label:] `\->' +[label:] `::' +.Ed +.Pp +The first format is used for defining variables. +The second format is used for distributing files to other hosts. +The third format is used for making lists of files that have been changed +since some given date. +The +.Ar source list +specifies a +list of files and/or directories on the local host which are to be used +as the master copy for distribution. +The +.Ar destination list +is the list of hosts to which these files are to be +copied. Each file in the source list is added to a list of changes +if the file is out of date on the host which is being updated (second format) or +the file is newer than the time stamp file (third format). +.Pp +Labels are optional. They are used to identify a command for partial updates. +.Pp +Newlines, tabs, and blanks are only used as separators and are +otherwise ignored. Comments begin with `#' and end with a newline. +.Pp +Variables to be expanded begin with `$' followed by one character or +a name enclosed in curly braces (see the examples at the end). +.Pp +The source and destination lists have the following format: +.Bd -literal -offset indent + +.Ed +or +.Bd -literal -offset indent -compact +`(' `)' +.Ed +.Pp +The shell meta-characters `[', `]', `{', `}', `*', and `?' +are recognized and expanded (on the local host only) in the same way as +.Xr csh 1 . +They can be escaped with a backslash. +The `~' character is also expanded in the same way as +.Xr csh 1 +but is expanded separately on the local and destination hosts. +When the +.Fl w +option is used with a file name that begins with `~', everything except the +home directory is appended to the destination name. +File names which do not begin with `/' or `~' use the destination user's +home directory as the root directory for the rest of the file name. +.Pp +The command list consists of zero or more commands of the following +format. +.Bd -ragged -offset indent -compact +.Bl -column except_patx pattern\ listx +.It `install' opt_dest_name `;' +.It `notify' `;' +.It `except' `;' +.It `except_pat' `;' +.It `special' string `;' +.El +.Ed +.Pp +The +.Ic install +command is used to copy out of date files and/or directories. +Each source file is copied to each host in the destination list. +Directories are recursively copied in the same way. +.Ar Opt_dest_name +is an optional parameter to rename files. +If no +.Ic install +command appears in the command list or +the destination name is not specified, +the source file name is used. +Directories in the path name will be created if they +do not exist on the remote host. +To help prevent disasters, a non-empty directory on a target host will +never be replaced with a regular file or a symbolic link. +However, under the `\-R' option a non-empty directory will be removed +if the corresponding filename is completely absent on the master host. +The +.Ar options +are `\-R', `\-h', `\-i', `\-v', `\-w', `\-y', and `\-b' +and have the same semantics as +options on the command line except they only apply to the files +in the source list. +The login name used on the destination host is the same as the local host +unless the destination name is of the format ``login@host". +.Pp +The +.Ic notify +command is used to mail the list of files updated (and any errors +that may have occurred) to the listed names. +If no `@' appears in the name, the destination host is appended to +the name +(e.g., name1@host, name2@host, ...). +.Pp +The +.Ic except +command is used to update all of the files in the source list +.Ic except +for the files listed in +.Ar name list . +This is usually used to copy everything in a directory except certain files. +.Pp +The +.Ic except_pat +command is like the +.Ic except +command except that +.Ar pattern list +is a list of regular expressions +(see +.Xr ed 1 +for details). +If one of the patterns matches some string within a file name, that file will +be ignored. +Note that since `\e' is a quote character, it must be doubled to become +part of the regular expression. Variables are expanded in +.Ar pattern list +but not shell file pattern matching characters. To include a `$', it +must be escaped with `\e'. +.Pp +The +.Ic special +command is used to specify +.Xr sh 1 +commands that are to be executed on the +remote host after the file in +.Ar name list +is updated or installed. +If the +.Ar name list +is omitted then the shell commands will be executed +for every file updated or installed. The shell variable `FILE' is set +to the current filename before executing the commands in +.Ar string . +.Ar String +starts and ends with `"' and can cross multiple lines in +.Ar distfile . +Multiple commands to the shell should be separated by `;'. +Commands are executed in the user's home directory on the host +being updated. +The +.Ar special +command can be used to rebuild private databases, etc. +after a program has been updated. +.Pp +The following is a small example: +.Bd -literal -offset indent +HOSTS = ( matisse root@arpa ) + +FILES = ( /bin /lib /usr/bin /usr/games +\t/usr/include/{*.h,{stand,sys,vax*,pascal,machine}/*.h} +\t/usr/lib /usr/man/man? /usr/ucb /usr/local/rdist ) + +EXLIB = ( Mail.rc aliases aliases.dir aliases.pag crontab dshrc +\tsendmail.cf sendmail.fc sendmail.hf sendmail.st uucp vfont ) + +${FILES} -> ${HOSTS} +\tinstall -R ; +\texcept /usr/lib/${EXLIB} ; +\texcept /usr/games/lib ; +\tspecial /usr/lib/sendmail "/usr/lib/sendmail -bz" ; + +srcs: +/usr/src/bin -> arpa +\texcept_pat ( \e\e.o\e$ /SCCS\e$ ) ; + +IMAGEN = (ips dviimp catdvi) + +imagen: +/usr/local/${IMAGEN} -> arpa +\tinstall /usr/local/lib ; +\tnotify ralph ; + +${FILES} :: stamp.cory +\tnotify root@cory ; +.Ed +.Sh FILES +.Bl -tag -width /tmp/rdist* -compact +.It Pa distfile +input command file +.It Pa /tmp/rdist* +temporary file for update lists +.El +.Sh SEE ALSO +.Xr sh 1 , +.Xr csh 1 , +.Xr stat 2 +.Sh HISTORY +The +.Nm rdist +command appeared in +.Bx 4.3 . +.Sh DIAGNOSTICS +A complaint about mismatch of rdist version numbers may really stem +from some problem with starting your shell, e.g., you are in too many groups. +.Sh BUGS +Source files must reside on the local host where +.Nm rdist +is executed. +.Pp +There is no easy way to have a special command executed after all files +in a directory have been updated. +.Pp +Variable expansion only works for name lists; there should be a general macro +facility. +.Pp +.Nm Rdist +aborts on files which have a negative mtime (before Jan 1, 1970). +.Pp +There should be a `force' option to allow replacement of non-empty directories +by regular files or symlinks.

+reads the standard input, interpreting each line as a row +of blank-separated entries in an array, +transforms the array according to the options, +and writes it on the standard output. +With no arguments it transforms stream input into a columnar +format convenient for terminal viewing. +.PP +The shape of the input array is deduced from the number of lines +and the number of columns on the first line. +If that shape is inconvenient, a more useful one might be +obtained by skipping some of the input with the \fB\-k\fP option. +Other options control interpretation of the input columns. +.PP +The shape of the output array is influenced by the +.I rows +and +.I cols +specifications, which should be positive integers. +If only one of them is a positive integer, +.I rs +computes a value for the other which will accommodate +all of the data. +When necessary, missing data are supplied in a manner +specified by the options and surplus data are deleted. +There are options to control presentation of the output columns, +including transposition of the rows and columns. +.PP +The options are described below. +.IP \fB\-c\fRx +Input columns are delimited by the single character \fIx\fP. +A missing \fIx\fP is taken to be `^I'. +.IP \fB\-s\fRx +Like \fB\-c\fR, but maximal strings of \fIx\fP are delimiters. +.IP \fB\-C\fRx +Output columns are delimited by the single character \fIx\fP. +A missing \fIx\fP is taken to be `^I'. +.IP \fB\-S\fRx +Like \fB\-C\fR, but padded strings of \fIx\fP are delimiters. +.IP \fB\-t\fR +Fill in the rows of the output array using the columns of the +input array, that is, transpose the input while honoring any +.I rows +and +.I cols +specifications. +.IP \fB\-T\fR +Print the pure transpose of the input, ignoring any +.I rows +or +.I cols +specification. +.IP \fB\-k\fRN +Ignore the first \fIN\fR lines of input. +.IP \fB\-K\fRN +Like \fB\-k\fR, but print the ignored lines. +.IP \fB\-g\fRN +The gutter width (inter-column space), normally 2, is taken to be \fIN\fR. +.IP \fB\-G\fRN +The gutter width has \fIN\fR percent of the maximum +column width added to it. +.IP \fB\-e\fR +Consider each line of input as an array entry. +.IP \fB\-n\fR +On lines having fewer entries than the first line, +use null entries to pad out the line. +Normally, missing entries are taken from the next line of input. +.IP \fB\-y\fR +If there are too few entries to make up the output dimensions, +pad the output by recycling the input from the beginning. +Normally, the output is padded with blanks. +.IP \fB\-h\fR +Print the shape of the input array and do nothing else. +The shape is just the number of lines and the number of +entries on the first line. +.IP \fB\-H\fR +Like \fB\-h\fR, but also print the length of each line. +.IP \fB\-j\fR +Right adjust entries within columns. +.IP \fB\-w\fRN +The width of the display, normally 80, is taken to be the positive +integer \fIN\fP. +.IP \fB\-m\fR +Do not trim excess delimiters from the ends of the output array. +.PP +With no arguments, +.I rs +transposes its input, and assumes one array entry per input line +unless the first non-ignored line is longer than the display width. +Option letters which take numerical arguments interpret a missing +number as zero unless otherwise indicated. +.SH EXAMPLES +.de IC +.IP +.ss 36 +.ft B +.. +.de NC +.br +.ss 12 +.PP +.. +.I Rs +can be used as a filter to convert the stream output +of certain programs (e.g., +.IR spell , +.IR du , +.IR file , +.IR look , +.IR nm , +.IR who , +and +.IR wc (1)) +into a convenient ``window'' format, as in +.IC

Source Code Control System +(\*S). +The presentation is geared to programmers +who are more concerned with +what +to do to get a task done +rather than how it works; +for this reason some of the examples +are not well explained. +For details of what the magic options do, +see the section on +.q "Further Information" . +.(l F +This is a working document. +Please send any comments or suggestions +to eric@Berkeley.Edu. +.)l +.sh 1 "Introduction" +.pp +\*S is a source management system. +Such a system maintains a record of versions of a system; +a record is kept with each set of changes +of what the changes are, +why they were made, +and who made them and when. +Old versions can be recovered, +and different versions can be maintained simultaneously. +In projects with more than one person, +\*S will insure that two people are not +editing the same file at the same time. +.pp +All versions of your program, +plus the log and other information, +is kept in a file called the +.q "s-file" . +There are three major operations +that can be performed on the s-file: +.np +Get a file for compilation (not for editing). +This operation retrieves a version of the file +from the s-file. +By default, the latest version is retrieved. +This file is intended for compilation, printing, or whatever; +it is specifically NOT intended to be edited +or changed in any way; +any changes made to a file retrieved +in this way will probably be lost. +.np +Get a file for editing. +This operation also retrieves a version of the file +from the s-file, +but this file is intended to be edited and then +incorporated back into the s-file. +Only one person may be editing a file at one time. +.np +Merge a file back into the s-file. +This is the companion operation to (2). +A new version number is assigned, +and comments are saved explaining why this change was made. +.sh 1 "Learning the Lingo" +.pp +There are a number of terms that are worth learning +before we go any farther. +.sh 2 "S-file" +.pp +The s-file +is a single file that holds all the different versions +of your file. +The s-file is stored in +differential format; +.i i.e. , +only the differences between versions are stored, +rather than the entire text of the new version. +This saves disk space +and allows selective changes to be removed later. +Also included in the s-file +is some header information for each version, +including the comments given by the person who +created the version explaining why the changes were made. +.sh 2 "Deltas" +.pp +Each set of changes to the s-file +(which is approximately [but not exactly!] equivalent +to a version of the file) +is called a +.i delta . +Although technically a delta only includes the +.i changes +made, +in practice +it is usual for +each delta to be made with respect to +all the deltas that have occurred before\**. +.(f +\**This matches normal usage, where the previous changes are not saved +at all, +so all changes are automatically based on all other changes +that have happened through history. +.)f +However, +it is possible to get a version of the file +that has selected deltas removed out of the middle +of the list of changes \*- +equivalent to removing your changes later. +.sh 2 "\*I's (or, version numbers)" +.pp +A \*I +(\*S Id) +is a number that represents a delta. +This is normally a two-part number +consisting of a +.q release +number and a +.q level +number. +Normally the release number stays the same, +however, +it is possible to move into a new release +if some major change is being made. +.pp +Since all past deltas are normally applied, +the \*I of the final delta applied +can be used to represent a version number of the file +as a whole. +.sh 2 "Id keywords" +.pp +When you get a version of a file +with intent to compile and install it +(\c +.i i.e. , +something other than edit it), +some special keywords are expanded inline +by \*S. +These +.i "Id Keywords" +can be used to include the current version number +or other information into the file. +All id keywords are of the form +.b % \c +.i x \c +.b % , +where +.i x +is an upper case letter. +For example, +.b %\&I\&% +is the \*I of the latest delta applied, +.b %\&W\&% +includes the module name, +\*I, +and a mark that makes it findable by a program, +and +.b %\&G\&% +is the date of the latest delta applied. +There are many others, +most of which are of dubious usefulness. +.pp +When you get a file for editing, +the id keywords are not expanded; +this is so that after you put them back in to the s-file, +they will be expanded automatically on each new version. +But notice: if you were to get them +expanded accidently, +then your file would appear to be the same version +forever more, +which would of course defeat the purpose. +Also, +if you should install a version of the program +without expanding the id keywords, +it will be impossible to tell what version it is +(since all it will have is +.q %\&W\&% +or whatever). +.sh 1 "Creating \*S Files" +.pp +To put source files +into +\*S +format, run the following shell script from csh: +.(b +mkdir SCCS save +foreach i (*.[ch]) + sccs admin \-i$i $i + mv $i save/$i +end +.)b +This will put the named files +into s-files +in the subdirectory +.q SCCS +The files will be removed from the current directory +and hidden away in the directory +.q save , +so the next thing you will probably want to do +is to get all the files +(described below). +When you are convinced that +\*S has correctly created the s-files, +you should remove the directory +.q save . +.pp +If you want to have id keywords in the files, +it is best to put them in before you create the s-files. +If you do not, +.i admin +will print +.q "No Id Keywords (cm7)" , +which is a warning message only. +.sh 1 "Getting Files for Compilation" +.pp +To get a copy of the latest version +of a file, +run +.(b +sccs get prog.c +.)b +\*S will respond: +.(b +1.1 +87 lines +.)b +meaning that version 1.1 was retrieved\** +.(f +\**Actually, +the \*I of the final delta applied was 1.1. +.)f +and that it has 87 lines. +The file +.i prog.c +will be created +in the current directory. +The file will be read-only +to remind you that you are not +supposed to change it. +.pp +This copy of the file +should not be changed, +since \*S is unable +to merge the changes +back into the s-file. +If you do make changes, +they will be lost the next time +someone does a +.i get . +.sh 1 "Changing Files (or, Creating Deltas)" +.sh 2 "Getting a copy to edit" +.pp +To edit a source file, +you must first get it, +requesting permission to edit it\**: +.(f +\**The +.q "edit" +command is equivalent to using the \-e +flag to +.i "get" , +as: +.(l +sccs get \-e prog.c +.)l +Keep this in mind when reading other documentation. +.)f +.(b +sccs edit prog.c +.)b +The response will be the same as with +.i get +except that it will also say: +.(b +New delta 1.2 +.)b +You then edit it, +using a standard text editor: +.(b +vi prog.c +.)b +.sh 2 "Merging the changes back into the s-file" +.pp +When the desired changes are made, +you can put your changes into the +\*S +file using the +.i delta +command: +.(b +sccs delta prog.c +.)b +.pp +Delta will prompt you for +.q "comments?" +before it merges the changes in. +At this prompt you should type a one-line description +of what the changes mean +(more lines can be entered by ending each line +except the last with a backslash\**). +.(f +\**Yes, this is a stupid default. +.)f +.i Delta +will then type: +.(b +1.2 +5 inserted +3 deleted +84 unchanged +.)b +saying that delta 1.2 was created, +and it inserted five lines, +removed three lines, +and left 84 lines unchanged\**. +.(f +\**Changes to a line are counted as a line deleted +and a line inserted. +.)f +The +.i prog.c +file will be removed; +it can be retrieved +using +.i get . +.sh 2 "When to make deltas" +.pp +It is probably unwise to make a delta +before every recompilation or test; +otherwise, +you tend to get a lot of deltas with comments like +.q "fixed compilation problem in previous delta" +or +.q "fixed botch in 1.3" . +However, +it is very important to delta everything +before installing a module for general use. +A good technique is to edit the files you need, +make all necessary changes and tests, +compiling and editing as often as necessary +without making deltas. +When you are satisfied that you have a working version, +delta everything being edited, +re-get them, +and recompile everything. +.sh 2 "What's going on: the info command" +.pp +To find out what files where being edited, +you can use: +.(b +sccs info +.)b +to print out all the files being edited +and other information such as the name of the user +who did the edit. +Also, +the command: +.(b +sccs check +.)b +is nearly equivalent to the +.i info +command, +except that it is silent if nothing is being edited, +and returns non-zero exit status if anything is being edited; +it can be used in an +.q install +entry in a makefile +to abort the install +if anything has not been properly deltaed. +.pp +If you know that everything being edited should be deltaed, +you can use: +.(b +sccs delta \`sccs tell\` +.)b +The +.i tell +command is similar to +.i info +except that only the names of files being edited +are output, +one per line. +.pp +All of these commands take a +.b \-b +flag +to ignore +.q branches +(alternate versions, described later) +and the +.b \-u +flag to only give files being edited by you. +The +.b \-u +flag takes an optional +.i user +argument, +giving only files being edited by that user. +For example, +.(b +sccs info \-ujohn +.)b +gives a listing of files being edited by john. +.sh 2 "ID keywords" +.pp +Id keywords can be inserted into your file +that will be expanded automatically by +.i get . +For example, +a line such as: +.(b +static char SccsId[] = "%\&W\&%\et%\&G\&%"; +.)b +will be replaced with something like: +.(b +static char SccsId[] = "@\&(#)prog.c 1.2 08/29/80"; +.)b +This tells you +the name and version +of the source file +and the time the delta was created. +The string +.q "@\&(#)" +is a special string +which signals the beginning +of an +\*S +Id keyword. +.sh 3 "The what command" +.pp +To find out what version of a program +is being run, +use: +.(b +sccs what prog.c /usr/bin/prog +.)b +which will print all strings +it finds that +begin with +.q "@\&(#)" . +This works on all types of files, +including binaries and libraries. +For example, the above command will output something like: +.(b +prog.c: + prog.c 1.2 08/29/80 +/usr/bin/prog: + prog.c 1.1 02/05/79 +.)b +From this I can see +that the source that I have in prog.c +will not compile into the same version +as the binary in /usr/bin/prog. +.sh 3 "Where to put id keywords" +.pp +ID keywords can be inserted anywhere, +including in comments, +but +Id Keywords that are compiled into the object module +are especially useful, +since it lets you find out what version of +the object is being run, +as well as the source. +However, +there is a cost: +data space is used up to store +the keywords, +and on small address space machines +this may be prohibitive. +.pp +When you put id keywords into header files, +it is important that you assign them to different variables. +For example, you might use: +.(b +static char AccessSid[] = "%\&W\&% %\&G\&%"; +.)b +in the file +.i access.h +and: +.(b +static char OpsysSid[] = "%\&W\&% %\&G\&%"; +.)b +in the file +.i opsys.h . +Otherwise, +you will get compilation errors because +.q SccsId +is redefined. +The problem with this is that if the header file +is included by many modules that are loaded together, +the version number of that header file is included +in the object module many times; +you may find it more to your taste +to put id keywords in header files +in comments. +.sh 2 "Keeping \*I's consistent across files" +.pp +With some care, +it is possible to keep the \*I's consistent +in multi-file systems. +The trick here is to always +.i edit +all files +at once. +The changes can then be made +to whatever files are necessary +and then all files +(even those not changed) +are redeltaed. +This can be done fairly easily +by just specifying the name of the directory +that the \*S files are in: +.(b +sccs edit SCCS +.)b +which will +.i edit +all files in that directory. +To make the delta, use: +.(b +sccs delta SCCS +.)b +You will be prompted for comments only once. +.sh 2 "Creating new releases" +.pp +When you want to create a new release +of a program, +you can specify the release number you want to create +on the +.i edit +command. +For example: +.(b +sccs edit \-r2 prog.c +.)b +will cause the next delta to be in release two +(that is, +it will be numbered 2.1). +Future deltas will automatically be in release two. +To change the release number +of an entire system, +use: +.(b +sccs edit \-r2 SCCS +.)b +.sh 1 "Restoring Old Versions" +.sh 2 "Reverting to old versions" +.pp +Suppose that after delta 1.2 +was stable +you made and released a delta 1.3. +But this introduced a bug, +so you made a delta 1.4 to correct it. +But 1.4 was still buggy, +and you decided you wanted to go back +to the old version. +You could +revert to delta 1.2 +by choosing the \*I in a get: +.(b +sccs get \-r1.2 prog.c +.)b +This will produce a version of +.i prog.c +that is delta 1.2 +that can be reinstalled so that work can proceed. +.pp +In some cases you don't know +what the \*I of the delta you want is. +However, +you can revert to the version of the program +that was running as of a certain date +by using the +.b \-c +(cutoff) flag. +For example, +.(b +sccs get \-c800722120000 prog.c +.)b +will retrieve whatever version was current +as of July 22, 1980 +at 12:00 noon. +Trailing components can be stripped off +(defaulting to their highest legal value), +and punctuation can be inserted in the obvious +places; +for example, +the above line could be equivalently stated: +.(b +sccs get \-c"80/07/22 12:00:00" prog.c +.)b +.sh 2 "Selectively deleting old deltas" +.pp +Suppose that you later decided +that you liked the changes in delta 1.4, +but that delta 1.3 should be removed. +You could do this by +.i excluding +delta 1.3: +.(b +sccs edit \-x1.3 prog.c +.)b +When delta 1.5 is made, +it will include the changes made +in delta 1.4, +but will exclude the changes made +in delta 1.3. +You can exclude a range of deltas +using a dash. +For example, +if you want to get rid of 1.3 and 1.4 +you can use: +.(b +sccs edit \-x1.3\-1.4 prog.c +.)b +which will exclude all deltas from 1.3 to 1.4. +Alternatively, +.(b +sccs edit \-x1.3\-1 prog.c +.)b +will exclude a range of deltas +from 1.3 to the current highest delta in release 1. +.pp +In certain cases when using +.b \-x +(or +.b \-i ; +see below) +there will be conflicts +between versions; +for example, it may be necessary +to both include and delete +a particular line. +If this happens, +\*S always prints out a message +telling the range of lines effected; +these lines should then be examined very carefully +to see if the version \*S got +is ok. +.pp +Since each delta +(in the sense of +.q "a set of changes" ) +can be excluded at will, +that this makes it most useful +to put each semantically distinct change +into its own delta. +.sh 1 "Auditing Changes" +.sh 2 "The prt command" +.pp +When you created a delta, +you presumably gave a reason for the delta +to the +.q "comments?" +prompt. +To print out these comments later, +use: +.(b +sccs prt prog.c +.)b +This will produce +a report +for each delta +of the \*I, +time and date of creation, +user who created the delta, +number of lines inserted, deleted, and unchanged, +and the comments associated with the delta. +For example, the output of the above command might be: +.(b +D 1.2 80/08/29 12:35:31 bill 2 1 00005/00003/00084 +removed "-q" option +.sp \n(psu +D 1.1 79/02/05 00:19:31 eric 1 0 00087/00000/00000 +date and time created 80/06/10 00:19:31 by eric +.)b +.sh 2 "Finding why lines were inserted" +.pp +To find out +why you inserted lines, +you can get a copy of the file +with each line +preceded by the \*I that created it: +.(b +sccs get \-m prog.c +.)b +You can then find out +what this delta did +by printing the comments using +.i prt . +.pp +To find out what lines are associated with a particular delta +(\c +.i e.g. , +1.3), +use: +.(b +sccs get \-m \-p prog.c \(bv grep \'^1.3\' +.)b +The +.b \-p +flag causes \*S to output the generated source +to the standard output rather than to a file. +.sh 2 "Finding what changes you have made" +.pp +When you are editing a file, +you can find out what changes you have made using: +.(b +sccs diffs prog.c +.)b +Most of the ``diff'' flags can be used. +To pass the +.b \-c +flag, +use +.b \-C . +.pp +To compare two versions that are in deltas, +use: +.(b +sccs sccsdiff -r1.3 -r1.6 prog.c +.)b +to see the differences between delta 1.3 and delta 1.6. +.sh 1 "Shorthand Notations" +.pp +There are several sequences of commands that get +executed frequently. +.i Sccs +tries to make it easy to do these. +.sh 2 "Delget" +.pp +A frequent requirement is to make a delta of some file +and then get that file. +This can be done by using: +.(b +sccs delget prog.c +.)b +which is entirely equivalent to using: +.(b +sccs delta prog.c +sccs get prog.c +.)b +The +.q deledit +command is equivalent to +.q delget +except that the +.q edit +command is used +instead of the +.q get +command. +.sh 2 "Fix" +.pp +Frequently, there are small bugs +in deltas, +e.g., compilation errors, +for which there is no reason to maintain an audit trail. +To +.i replace +a delta, use: +.(b +sccs fix \-r1.4 prog.c +.)b +This will get a copy of delta 1.4 of prog.c for you to edit +and then delete delta 1.4 from the \*S file. +When you do a delta of prog.c, +it will be delta 1.4 again. +The \-r flag must be specified, +and the delta that is specified must be a leaf delta, +i.e., no other deltas may have been made subsequent +to the creation of that delta. +.sh 2 "Unedit" +.pp +If you found you edited a file +that you did not want to edit, +you can back out by using: +.(b +sccs unedit prog.c +.)b +.sh 2 "The \-d flag" +.pp +If you are working on a project +where the \*S code is in a directory somewhere, +you may be able to simplify things +by using a shell alias. +For example, +the alias: +.(b +alias syssccs sccs \-d/usr/src +.)b +will allow you to issue commands such as: +.(b +syssccs edit cmd/who.c +.)b +which will look for the file +.q "/usr/src/cmd/SCCS/who.c" . +The file +.q who.c +will always be created in your current directory +regardless of the value of the \-d flag. +.sh 1 "Using \*S on a Project" +.pp +Working on a project with several people +has its own set of special problems. +The main problem occurs when two people +modify a file at the same time. +\*S prevents this by locking an s-file +while it is being edited. +.pp +As a result, +files should not be reserved for editing +unless they are actually being edited at the time, +since this will prevent other people on the project +from making necessary changes. +For example, +a good scenario for working might be: +.(b +sccs edit a.c g.c t.c +vi a.c g.c t.c +# do testing of the (experimental) version +sccs delget a.c g.c t.c +sccs info +# should respond "Nothing being edited" +make install +.)b +.pp +As a general rule, +all source files should be deltaed +before installing the program for general use. +This will insure that it is possible +to restore any version in use at any time. +.sh 1 "Saving Yourself" +.sh 2 "Recovering a munged edit file" +.pp +Sometimes you may find +that you have destroyed or trashed +a file that you were trying to edit\**. +.(f +\**Or given up and decided to start over. +.)f +Unfortunately, +you can't just remove it +and re-\c +.i edit +it; +\*S keeps track +of the fact +that someone is trying to edit it, +so it won't let you do it again. +Neither can you just get it using +.i get , +since that would expand the Id keywords. +Instead, +you can say: +.(b +sccs get \-k prog.c +.)b +This will not expand the Id keywords, +so it is safe to do a delta +with it. +.pp +Alternately, +you can +.i unedit +and +.i edit +the file. +.sh 2 "Restoring the s-file" +.pp +In particularly bad circumstances, +the \*S file itself +may get munged. +The most common way this happens +is that it gets edited. +Since \*S keeps a checksum, +you will get errors every time you read the file. +To fix this checksum, use: +.(b +sccs admin \-z prog.c +.)b +.sh 1 "Using the Admin Command" +.pp +There are a number of parameters that can be set +using the +.i admin +command. +The most interesting of these are flags. +Flags can be added by using the +.b \-f +flag. +For example: +.(b +sccs admin \-fd1 prog.c +.)b +sets the +.q d +flag to the value +.q 1 . +This flag can be deleted by using: +.(b +sccs admin \-dd prog.c +.)b +The most useful flags are: +.nr ii 7n +.ip "b" +Allow branches to be made using the +\-b +flag to +.i edit . +.ip "d\fISID\fP" +Default \*I to be used on a +.i get +or +.i edit . +If this is just a release number +it constrains the +version +to a particular release only. +.ip "i" +Give a fatal error +if there are no Id Keywords in a file. +This is useful to guarantee that a version of the +file does not get merged into the s-file +that has the Id Keywords inserted as constants +instead of internal forms. +.ip "y" +The +.q type +of the module. +Actually, +the value of this flag is unused by \*S +except that it replaces the +.b %\&Y\&% +keyword. +.pp +The +.b \-t\fIfile\fR +flag can be used +to store descriptive text +from +.i file . +This descriptive text might be the documentation +or a design and implementation document. +Using the +.b \-t +flag insures that if the \*S file is sent, +the documentation will be sent also. +If +.i file +is omitted, +the descriptive text is deleted. +To see the descriptive text, +use +.q "prt \-t" . +.pp +The +.i admin +command can be used safely +any number of times on files. +A file need not be gotten +for +.i admin +to work. +.sh 1 "Maintaining Different Versions (Branches)" +.pp +Sometimes it is convenient +to maintain an experimental version of a program +for an extended period +while normal maintenance continues +on the version in production. +This can be done using a +.q branch. +Normally deltas continue in a straight line, +each depending on the delta before. +Creating a branch +.q "forks off" +a version of the program. +.pp +The ability to create branches +must be enabled in advance using: +.(b +sccs admin \-fb prog.c +.)b +The +.b \-fb +flag can be specified when the +\*S file is first created. +.sh 2 "Creating a branch" +.pp +To create a branch, use: +.(b +sccs edit \-b prog.c +.)b +This will create a branch +with (for example) \*I 1.5.1.1. +The deltas for this version +will be numbered +1.5.1.\c +.i n . +.sh 2 "Getting from a branch" +.pp +Deltas in a branch are normally not included +when you do a get. +To get these versions, +you will have to say: +.(b +sccs get \-r1.5.1 prog.c +.)b +.sh 2 "Merging a branch back into the main trunk" +.pp +At some point you will have finished the experiment, +and if it was successful +you will want to incorporate it into the release version. +But in the meantime +someone may have created a delta 1.6 +that you don't want to lose. +The commands: +.(b +sccs edit \-i1.5.1.1\-1.5.1 prog.c +sccs delta prog.c +.)b +will merge all of your changes +into the release system. +If some of the changes conflict, +get will print an error; +the generated result +should be carefully examined +before the delta is made. +.sh 2 "A more detailed example" +.pp +The following technique might be used +to maintain a different version of a program. +First, +create a directory to contain the new version: +.(b +mkdir ../newxyz +cd ../newxyz +.)b +Edit a copy of the program +on a branch: +.(b +sccs \-d../xyz edit prog.c +.)b +When using the old version, +be sure to use the +.b \-b +flag to info, check, tell, and clean +to avoid confusion. +For example, use: +.(b +sccs info \-b +.)b +when in the directory +.q xyz . +.pp +If you want to save a copy of the program +(still on the branch) +back in the s-file, +you can use: +.(b +sccs -d../xyz deledit prog.c +.)b +which will do a delta on the branch +and reedit it for you. +.pp +When the experiment is complete, merge it back into the s-file +using delta: +.(b +sccs -d../xyz delta prog.c +.)b +At this point you must decide whether this version +should be merged back into the trunk +(\c +.i i.e. +the default version), +which may have undergone changes. +If so, it can be merged using the +.b \-i +flag to +.i edit +as described above. +.sh 2 "A warning" +.pp +Branches should be kept to a minimum. +After the first branch from the trunk, +\*I's are assigned rather haphazardly, +and the structure gets complex fast. +.sh 1 "Using \*S with Make" +.pp +\*S and make can be made to work together +with a little care. +A few sample makefiles +for common applications are shown. +.pp +There are a few basic entries that every makefile +ought to have. +These are: +.nr ii 1i +.ip a.out +(or whatever the makefile generates.) +This entry regenerates whatever this makefile is +supposed to regenerate. +If the makefile regenerates many things, +this should be called +.q all +and should in turn +have dependencies on everything +the makefile can generate. +.ip install +Moves the objects to the final +resting place, +doing any special +.i chmod 's +or +.i ranlib 's +as appropriate. +.ip sources +Creates all the source files from \*S files. +.ip clean +Removes all files from the current directory +that can be regenerated from \*S files. +.ip print +Prints the contents of the directory. +.lp +The examples shown below are only partial examples, +and may omit some of these entries +when they are deemed to be obvious. +.pp +The +.i clean +entry should not remove files that can be +regenerated from the \*S files. +It is sufficiently important to have the +source files around at all times +that the only time they should be removed +is when the directory is being mothballed. +To do this, the command: +.(b +sccs clean +.)b +can be used. +This will remove all files for which an s-file +exists, +but which is not being edited. +.sh 2 "To maintain single programs" +.pp +Frequently there are directories with several +largely unrelated programs +(such as simple commands). +These can be put into a single makefile: +.(b +LDFLAGS= \-i \-s +.sp \n(psu +prog: prog.o + $(CC) $(LDFLAGS) \-o prog prog.o +prog.o: prog.c prog.h +.sp \n(psu +example: example.o + $(CC) $(LDFLAGS) \-o example example.o +example.o: example.c +.sp \n(psu +\&.DEFAULT: + sccs get $< +.)b +The trick here +is that the .DEFAULT rule +is called every time +something is needed +that does not exist, +and no other rule exists to make it. +The explicit dependency of the +.b \&.o +file on the +.b \&.c +file is important. +Another way of doing the same thing is: +.(b +SRCS= prog.c prog.h example.c +.sp \n(psu +LDFLAGS= \-i \-s +.sp \n(psu +prog: prog.o + $(CC) $(LDFLAGS) \-o prog prog.o +prog.o: prog.h +.sp \n(psu +example: example.o + $(CC) $(LDFLAGS) \-o example example.o +.sp \n(psu +sources: $(SRCS) +$(SRCS): + sccs get $@ +.)b +There are a couple of advantages to this approach: +(1) the explicit dependencies of the .o on the .c files are +not needed, +(2) there is an entry called "sources" so if you want to get +all the sources you can just say +.q "make sources" , +and +(3) the makefile is less likely to do confusing things +since it won't try to +.i get +things that do not exist. +.sh 2 "To maintain a library" +.pp +Libraries that are largely static +are best updated using explicit commands, +since +.i make +doesn't know about updating them properly. +However, +libraries that are in the process of being developed +can be handled quite adequately. +The problem is that the .o files +have to be kept out of the library +as well as in the library. +.(b +# configuration information +OBJS= a.o b.o c.o d.o +SRCS= a.c b.c c.c d.s x.h y.h z.h +TARG= /usr/lib +.sp \n(psu +# programs +GET= sccs get +REL= +AR= \-ar +RANLIB= ranlib +.sp \n(psu +lib.a: $(OBJS) + $(AR) rvu lib.a $(OBJS) + $(RANLIB) lib.a +.sp \n(psu +install: lib.a + sccs check + cp lib.a $(TARG)/lib.a + $(RANLIB) $(TARG)/lib.a +.sp \n(psu +sources: $(SRCS) +$(SRCS): + $(GET) $(REL) $@ +.sp \n(psu +print: sources + pr *.h *.[cs] +clean: + rm \-f *.o + rm \-f core a.out $(LIB) +.)b +.pp +The +.q "$(REL)" +in the get +can be used to get old versions +easily; for example: +.(b +make b.o REL=\-r1.3 +.)b +.pp +The +.i install +entry includes the line +.q "sccs check" +before anything else. +This guarantees that all the s-files +are up to date +(\c +.i i.e. , +nothing is being edited), +and will abort the +.i make +if this condition is not met. +.sh 2 "To maintain a large program" +.(b +OBJS= a.o b.o c.o d.o +SRCS= a.c b.c c.y d.s x.h y.h z.h +.sp \n(psu +GET= sccs get +REL= +.sp \n(psu +a.out: $(OBJS) + $(CC) $(LDFLAGS) $(OBJS) $(LIBS) +.sp \n(psu +sources: $(SRCS) +$(SRCS): + $(GET) $(REL) $@ +.)b +(The +.i print +and +.i clean +entries are identical to the previous case.) +This makefile requires copies of the source and object files +to be kept during development. +It is probably also wise to include lines of the form: +.(b +a.o: x.h y.h +b.o: z.h +c.o: x.h y.h z.h +z.h: x.h +.)b +so that modules will be recompiled +if header files change. +.pp +Since +.i make +does not do transitive closure on dependencies, +you may find in some makefiles lines like: +.(b +z.h: x.h + touch z.h +.)b +This would be used in cases where file z.h +has a line: +.(b +#include "x.h" +.)b +in order to bring the mod date of z.h in line +with the mod date of x.h. +When you have a makefile such as above, +the +.i touch +command can be removed completely; +the equivalent effect will be achieved +by doing an automatic +.i get +on z.h. +.sh 1 "Further Information" +.pp +The +.i "SCCS/PWB User's Manual" +gives a deeper description +of how to use \*S. +Of particular interest +are the numbering of branches, +the l-file, +which gives a description of what deltas were used on a get, +and certain other \*S commands. +.pp +The \*S manual pages +are a good last resort. +These should be read by software managers +and by people who want to know +everything about everything. +.pp +Both of these documents were written without the +.i sccs +front end in mind, +so most of the examples are slightly different from those +in this document. +.bp +.sz 12 +.ce +.b "Quick Reference" +.sz +.sp 2 +.sh 1 Commands

The main thing it does is automatically put the +** string "SCCS/s." on the front of names. Also, it has a +** couple of things that are designed to shorten frequent +** combinations, e.g., "delget" which expands to a "delta" +** and a "get". +** +** This program can also function as a setuid front end. +** To do this, you should copy the source, renaming it to +** whatever you want, e.g., "syssccs". Change any defaults +** in the program (e.g., syssccs might default -d to +** "/usr/src/sys"). Then recompile and put the result +** as setuid to whomever you want. In this mode, sccs +** knows to not run setuid for certain programs in order +** to preserve security, and so forth. +** +** Usage: +** sccs [flags] command [args] +** +** Flags: +** -d represents a directory to search +** out of. It should be a full pathname +** for general usage. E.g., if is +** "/usr/src/sys", then a reference to the +** file "dev/bio.c" becomes a reference to +** "/usr/src/sys/dev/bio.c". +** -p prepends to the final component +** of the pathname. By default, this is +** "SCCS". For example, in the -d example +** above, the path then gets modified to +** "/usr/src/sys/dev/SCCS/s.bio.c". In +** more common usage (without the -d flag), +** "prog.c" would get modified to +** "SCCS/s.prog.c". In both cases, the +** "s." gets automatically prepended. +** -r run as the real user. +** +** Commands: +** admin, +** get, +** delta, +** rmdel, +** cdc, +** etc. Straight out of SCCS; only difference +** is that pathnames get modified as +** described above. +** enter Front end doing "sccs admin -i " +** create Macro for "enter" followed by "get". +** edit Macro for "get -e". +** unedit Removes a file being edited, knowing +** about p-files, etc. +** delget Macro for "delta" followed by "get". +** deledit Macro for "delta" followed by "get -e". +** branch Macro for "get -b -e", followed by "delta +** -s -n", followd by "get -e -t -g". +** diffs "diff" the specified version of files +** and the checked-out version. +** print Macro for "prs -e" followed by "get -p -m". +** tell List what files are being edited. +** info Print information about files being edited. +** clean Remove all files that can be +** regenerated from SCCS files. +** check Like info, but return exit status, for +** use in makefiles. +** fix Remove a top delta & reedit, but save +** the previous changes in that delta. +** +** Compilation Flags: +** UIDUSER -- determine who the user is by looking at the +** uid rather than the login name -- for machines +** where SCCS gets the user in this way. +** SCCSDIR -- if defined, forces the -d flag to take on +** this value. This is so that the setuid +** aspects of this program cannot be abused. +** This flag also disables the -p flag. +** SCCSPATH -- the default for the -p flag. +** MYNAME -- the title this program should print when it +** gives error messages. +** +** Compilation Instructions: +** cc -O -n -s sccs.c +** The flags listed above can be -D defined to simplify +** recompilation for variant versions. +** +** Author: +** Eric Allman, UCB/INGRES +** Copyright 1980 Regents of the University of California +*/ + + +/******************* Configuration Information ********************/ + +# ifndef SCCSPATH +# define SCCSPATH "SCCS" /* pathname in which to find s-files */ +# endif NOT SCCSPATH + +# ifndef MYNAME +# define MYNAME "sccs" /* name used for printing errors */ +# endif NOT MYNAME + +/**************** End of Configuration Information ****************/ + +typedef char bool; +# define TRUE 1 +# define FALSE 0 + +# define bitset(bit, word) ((bool) ((bit) & (word))) + +struct sccsprog +{ + char *sccsname; /* name of SCCS routine */ + short sccsoper; /* opcode, see below */ + short sccsflags; /* flags, see below */ + char *sccspath; /* pathname of binary implementing */ +}; + +/* values for sccsoper */ +# define PROG 0 /* call a program */ +# define CMACRO 1 /* command substitution macro */ +# define FIX 2 /* fix a delta */ +# define CLEAN 3 /* clean out recreatable files */ +# define UNEDIT 4 /* unedit a file */ +# define SHELL 5 /* call a shell file (like PROG) */ +# define DIFFS 6 /* diff between sccs & file out */ +# define DODIFF 7 /* internal call to diff program */ +# define ENTER 8 /* enter new files */ + +/* bits for sccsflags */ +# define NO_SDOT 0001 /* no s. on front of args */ +# define REALUSER 0002 /* protected (e.g., admin) */ + +/* modes for the "clean", "info", "check" ops */ +# define CLEANC 0 /* clean command */ +# define INFOC 1 /* info command */ +# define CHECKC 2 /* check command */ +# define TELLC 3 /* give list of files being edited */ + +/* +** Description of commands known to this program. +** First argument puts the command into a class.

All the comments are notes taken while +implementing a POSIX-compatible version of sed, and should not be +interpreted as official opinions or criticism towards the POSIX committee. +All uses of "POSIX" refer to section 4.55, Draft 12 of POSIX 1003.2. + + 1. 32V and BSD derived implementations of sed strip the text + arguments of the a, c and i commands of their initial blanks, + i.e. + + #!/bin/sed -f + a\ + foo\ + \ indent\ + bar + + produces: + + foo + indent + bar + + POSIX does not specify this behavior as the System V versions of + sed do not do this stripping. The argument against stripping is + that it is difficult to write sed scripts that have leading blanks + if they are stripped. The argument for stripping is that it is + difficult to write readable sed scripts unless indentation is allowed + and ignored, and leading whitespace is obtainable by entering a + backslash in front of it. This implementation follows the BSD + historic practice. + + 2. Historical versions of sed required that the w flag be the last + flag to an s command as it takes an additional argument. This + is obvious, but not specified in POSIX. + + 3. Historical versions of sed required that whitespace follow a w + flag to an s command. This is not specified in POSIX. This + implementation permits whitespace but does not require it. + + 4. Historical versions of sed permitted any number of whitespace + characters to follow the w command. This is not specified in + POSIX. This implementation permits whitespace but does not + require it. + + 5. The rule for the l command differs from historic practice. Table + 2-15 includes the various ANSI C escape sequences, including \\ + for backslash. Some historical versions of sed displayed two + digit octal numbers, too, not three as specified by POSIX. POSIX + is a cleanup, and is followed by this implementation. + + 6. The POSIX specification for ! does not specify that for a single + command the command must not contain an address specification + whereas the command list can contain address specifications. The + specification for ! implies that "3!/hello/p" works, and it never + has, historically. Note, + + 3!{ + /hello/p + } + + does work. + + 7. POSIX does not specify what happens with consecutive ! commands + (e.g. /foo/!!!p). Historic implementations allow any number of + !'s without changing the behaviour. (It seems logical that each + one might reverse the behaviour.) This implementation follows + historic practice. + + 8. Historic versions of sed permitted commands to be separated + by semi-colons, e.g. 'sed -ne '1p;2p;3q' printed the first + three lines of a file. This is not specified by POSIX. + Note, the ; command separator is not allowed for the commands + a, c, i, w, r, :, b, t, # and at the end of a w flag in the s + command. This implementation follows historic practice and + implements the ; separator. + + 9. Historic versions of sed terminated the script if EOF was reached + during the execution of the 'n' command, i.e.: + + sed -e ' + n + i\ + hello + ' +# +# note -- TWO carriage returns, a peculiarity of sed), this will output the +# sequence of states involved in moving 4 rings, the largest called "a" and +# the smallest called "d", from the first to the second of three towers, so +# that the rings on any tower at any time are in descending order of size. +# You can start with a different arrangement and a different number of rings, +# say :ce:b:ax: and it will give the shortest procedure for moving them all +# to the middle tower. The rules are: the names of the rings must all be +# lower-case letters, they must be input within 3 fields (representing the +# towers) and delimited by 4 colons, such that the letters within each field +# are in alphabetical order (i.e. rings are in descending order of size). +# +# For the benefit of anyone who wants to figure out the script, an "internal" +# line of the form +# b:0abx:1a2b3 :2 :3x2 +# has the following meaning: the material after the three markers :1, :2, +# and :3 represents the three towers; in this case the current set-up is +# ":ab : :x :". The numbers after a, b and x in these fields indicate +# that the next time it gets a chance, it will move a to tower 2, move b +# to tower 3, and move x to tower 2. The string after :0 just keeps track +# of the alphabetical order of the names of the rings. The b at the +# beginning means that it is now dealing with ring b (either about to move +# it, or re-evaluating where it should next be moved to). +# +# Although this version is "limited" to 26 rings because of the size of the +# alphabet, one could write a script using the same idea in which the rings +# were represented by arbitrary [strings][within][brackets], and in place of +# the built-in line of the script giving the order of the letters of the +# alphabet, it would accept from the user a line giving the ordering to be +# assumed, e.g. [ucbvax][decvax][hplabs][foo][bar]. +# +# George Bergman +# Math, UC Berkeley 94720 USA + +# cleaning, diagnostics +s/ *//g +/^$/d +/[^a-z:]/{a\ +Illegal characters: use only a-z and ":".

+.Dd "December 30, 1993" +.Dt SED 1 +.Os +.Sh NAME +.Nm sed +.Nd stream editor +.Sh SYNOPSIS +.Nm sed +.Op Fl an +.Ar command +.Op Ar file ... +.Nm sed +.Op Fl an +.Op Fl e Ar command +.Op Fl f Ar command_file +.Op Ar file ... +.Sh DESCRIPTION +The +.Nm sed +utility reads the specified files, or the standard input if no files +are specified, modifying the input as specified by a list of commands. +The input is then written to the standard output. +.Pp +A single command may be specified as the first argument to +.Nm sed . +Multiple commands may be specified by using the +.Fl e +or +.Fl f +options. +All commands are applied to the input in the order they are specified +regardless of their origin. +.Pp +The following options are available: +.Bl -tag -width indent +.It Fl a +The files listed as parameters for the +.Dq w +functions are created (or truncated) before any processing begins, +by default. +The +.Fl a +option causes +.Nm sed +to delay opening each file until a command containing the related +.Dq w +function is applied to a line of input. +.It Fl e Ar command +Append the editing commands specified by the +.Ar command +argument +to the list of commands. +.It Fl f Ar command_file +Append the editing commands found in the file +.Ar command_file +to the list of commands. +The editing commands should each be listed on a separate line. +.It Fl n +By default, each line of input is echoed to the standard output after +all of the commands have been applied to it. +The +.Fl n +option suppresses this behavior. +.El +.Pp +The form of a +.Nm sed +command is as follows: +.sp +.Dl [address[,address]]function[arguments] +.sp +Whitespace may be inserted before the first address and the function +portions of the command. +.Pp +Normally, +.Nm sed +cyclically copies a line of input, not including its terminating newline +character, into a +.Em "pattern space" , +(unless there is something left after a +.Dq D +function), +applies all of the commands with addresses that select that pattern space, +copies the pattern space to the standard output, appending a newline, and +deletes the pattern space. +.Pp +Some of the functions use a +.Em "hold space" +to save all or part of the pattern space for subsequent retrieval. +.Sh "Sed Addresses" +An address is not required, but if specified must be a number (that counts +input lines +cumulatively across input files), a dollar +.Po +.Dq $ +.Pc +character that addresses the last line of input, or a context address +(which consists of a regular expression preceded and followed by a +delimiter). +.Pp +A command line with no addresses selects every pattern space. +.Pp +A command line with one address selects all of the pattern spaces +that match the address. +.Pp +A command line with two addresses selects the inclusive range from +the first pattern space that matches the first address through the next +pattern space that matches the second. +(If the second address is a number less than or equal to the line number +first selected, only that line is selected.) +Starting at the first line following the selected range, +.Nm sed +starts looking again for the first address. +.Pp +Editing commands can be applied to non-selected pattern spaces by use +of the exclamation character +.Po +.Dq ! +.Pc +function. +.Sh "Sed Regular Expressions" +The +.Nm sed +regular expressions are basic regular expressions (BRE's, see +.Xr regex 3 +for more information). +In addition, +.Nm sed +has the following two additions to BRE's: +.sp +.Bl -enum -compact +.It +In a context address, any character other than a backslash +.Po +.Dq \e +.Pc +or newline character may be used to delimit the regular expression. +Also, putting a backslash character before the delimiting character +causes the character to be treated literally. +For example, in the context address \exabc\exdefx, the RE delimiter +is an +.Dq x +and the second +.Dq x +stands for itself, so that the regular expression is +.Dq abcxdef . +.sp +.It +The escape sequence \en matches a newline character embedded in the +pattern space. +You can't, however, use a literal newline character in an address or +in the substitute command. +.El +.Pp +One special feature of +.Nm sed +regular expressions is that they can default to the last regular +expression used. +If a regular expression is empty, i.e. just the delimiter characters +are specified, the last regular expression encountered is used instead. +The last regular expression is defined as the last regular expression +used as part of an address or substitute command, and at run-time, not +compile-time. +For example, the command +.Dq /abc/s//XXX/ +will substitute +.Dq XXX +for the pattern +.Dq abc . +.Sh "Sed Functions" +In the following list of commands, the maximum number of permissible +addresses for each command is indicated by [0addr], [1addr], or [2addr], +representing zero, one, or two addresses. +.Pp +The argument +.Em text +consists of one or more lines. +To embed a newline in the text, precede it with a backslash. +Other backslashes in text are deleted and the following character +taken literally. +.Pp +The +.Dq r +and +.Dq w +functions take an optional file parameter, which should be separated +from the function letter by white space. +Each file given as an argument to +.Nm sed +is created (or its contents truncated) before any input processing begins. +.Pp +The +.Dq b , +.Dq r , +.Dq s , +.Dq t , +.Dq w , +.Dq y , +.Dq ! , +and +.Dq \&: +functions all accept additional arguments. +The following synopses indicate which arguments have to be separated from +the function letters by white space characters. +.Pp +Two of the functions take a function-list. +This is a list of +.Nm sed +functions separated by newlines, as follows: +.Bd -literal -offset indent +{ function + function + ... + function +} +.Ed +.Pp +The +.Dq { +can be preceded by white space and can be followed by white space. +The function can be preceded by white space. +The terminating +.Dq } +must be preceded by a newline or optional white space. +.sp +.Bl -tag -width "XXXXXX" -compact +.It [2addr] function-list +Execute function-list only when the pattern space is selected. +.sp +.It [1addr]a\e +.It text +.br +Write +.Em text +to standard output immediately before each attempt to read a line of input, +whether by executing the +.Dq N +function or by beginning a new cycle. +.sp +.It [2addr]b[lable] +Branch to the +.Dq \&: +function with the specified label. +If the label is not specified, branch to the end of the script. +.sp +.It [2addr]c\e +.It text +.br +Delete the pattern space. +With 0 or 1 address or at the end of a 2-address range, +.Em text +is written to the standard output. +.sp +.It [2addr]d +Delete the pattern space and start the next cycle. +.sp +.It [2addr]D +Delete the initial segment of the pattern space through the first +newline character and start the next cycle. +.sp +.It [2addr]g +Replace the contents of the pattern space with the contents of the +hold space. +.sp +.It [2addr]G +Append a newline character followed by the contents of the hold space +to the pattern space. +.sp +.It [2addr]h +Replace the contents of the hold space with the contents of the +pattern space. +.sp +.It [2addr]H +Append a newline character followed by the contents of the pattern space +to the hold space. +.sp +.It [1addr]i\e +.It text +.br +Write +.Em text +to the standard output. +.sp +.It [2addr]l +(The letter ell.) +Write the pattern space to the standard output in a visually unambiguous +form. +This form is as follows: +.sp

+.El +.Pp +Nonprintable characters are written as three-digit octal numbers (with a +preceding backslash) for each byte in the character (most significant byte +first). +Long lines are folded, with the point of folding indicated by displaying +a backslash followed by a newline. +The end of each line is marked with a +.Dq $ . +.sp +.It [2addr]n +Write the pattern space to the standard output if the default output has +not been suppressed, and replace the pattern space with the next line of +input. +.sp +.It [2addr]N +Append the next line of input to the pattern space, using an embedded +newline character to separate the appended material from the original +contents. +Note that the current line number changes. +.sp +.It [2addr]p +Write the pattern space to standard output. +.sp +.It [2addr]P +Write the pattern space, up to the first newline character to the +standard output. +.sp +.It [1addr]q +Branch to the end of the script and quit without starting a new cycle. +.sp +.It [1addr]r file +Copy the contents of +.Em file +to the standard output immediately before the next attempt to read a +line of input. +If +.Em file +cannot be read for any reason, it is silently ignored and no error +condition is set. +.sp +.It [2addr]s/regular expression/replacement/flags +Substitute the replacement string for the first instance of the regular +expression in the pattern space. +Any character other than backslash or newline can be used instead of +a slash to delimit the RE and the replacement. +Within the RE and the replacement, the RE delimiter itself can be used as +a literal character if it is preceded by a backslash. +.Pp +An ampersand +.Po +.Dq & +.Pc +appearing in the replacement is replaced by the string matching the RE. +The special meaning of +.Dq & +in this context can be suppressed by preceding it by a backslash. +The string +.Dq \e# , +where +.Dq # +is a digit, is replaced by the text matched +by the corresponding backreference expression (see +.Xr re_format 7 ). +.Pp +A line can be split by substituting a newline character into it. +To specify a newline character in the replacement string, precede it with +a backslash. +.Pp +The value of +.Em flags +in the substitute function is zero or more of the following: +.Bl -tag -width "XXXXXX" -offset indent +.It "0 ... 9" +Make the substitution only for the N'th occurrence of the regular +expression in the pattern space. +.It g +Make the substitution for all non-overlapping matches of the +regular expression, not just the first one. +.It p +Write the pattern space to standard output if a replacement was made. +If the replacement string is identical to that which it replaces, it +is still considered to have been a replacement. +.It w Em file +Append the pattern space to +.Em file +if a replacement was made. +If the replacement string is identical to that which it replaces, it +is still considered to have been a replacement. +.El +.sp +.It [2addr]t [label] +Branch to the +.Dq : +function bearing the

+character. +.sp +.It [2addr]!function +.It [2addr]!function-list +Apply the function or function-list only to the lines that are +.Em not +selected by the address(es). +.sp +.It [0addr]:label +This

The +upper window depicts the current system load average. The +information displayed in the lower window may vary, depending on +user commands. The last line on the screen is reserved for user +input and error messages. +.Pp +By default +.Nm systat +displays the processes getting the largest percentage of the processor +in the lower window. Other displays show swap space usage, disk +.Tn I/O +statistics (a la +.Xr iostat 1 ) , +virtual memory statistics (a la +.Xr vmstat 1 ) , +network ``mbuf'' utilization, and network connections (a la +.Xr netstat 1 ) . +.Pp +Input is interpreted at two different levels. +A ``global'' command interpreter processes all keyboard input. +If this command interpreter fails to recognize a command, the +input line is passed to a per-display command interpreter. This +allows each display to have certain display-specific commands. +.Pp +Command line options: +.Bl -tag -width "refresh_interval" +.It Fl Ns Ar display +The +.Fl +flag expects +.Ar display +to be one of: +.Ic pigs , +.Ic iostat , +.Ic swap , +.Ic mbufs , +.Ic vmstat +or +.Ic netstat . +These displays can also be requested interactively (without the +.Dq Fl ) +and are described in +full detail below. +.It Ar refresh-interval +The +.Ar refresh-value +specifies the screen refresh time interval in seconds. +.El +.Pp +Certain characters cause immediate action by +.Nm systat . +These are +.Bl -tag -width Fl +.It Ic \&^L +Refresh the screen. +.It Ic \&^G +Print the name of the current ``display'' being shown in +the lower window and the refresh interval. +.It Ic \&^Z +Stop +.Nm systat . +.It Ic \&: +Move the cursor to the command line and interpret the input +line typed as a command.

Statistics on processor use appear as +bar graphs of the amount of time executing in user mode (``user''), +in user mode running low priority processes (``nice''), in +system mode (``system''), and idle (``idle''). Statistics +on disk throughput show, for each drive, kilobytes of data transferred, +number of disk transactions performed, and average seek time +(in milliseconds). This information may be displayed as +bar graphs or as rows of numbers which scroll downward. Bar +graphs are shown by default; +.Pp +The following commands are specific to the +.Ic iostat +display; the minimum unambiguous prefix may be supplied. +.Pp +.Bl -tag -width Fl -compact +.It Cm numbers +Show the disk +.Tn I/O +statistics in numeric form. Values are +displayed in numeric columns which scroll downward. +.It Cm bars +Show the disk +.Tn I/O +statistics in bar graph form (default). +.It Cm msps +Toggle the display of average seek time (the default is to +not display seek times). +.El +.It Ic swap +Show information about swap space usage on all the +swap areas compiled into the kernel. +The first column is the device name of the partition. +The next column is the total space available in the partition. +The +.Ar Used +column indicates the total blocks used so far; +the graph shows the percentage of space in use on each partition. +If there are more than one swap partition in use, +a total line is also shown. +Areas known to the kernel, but not in use are shown as not available. +.It Ic mbufs +Display, in the lower window, the number of mbufs allocated +for particular uses, i.e. data, socket structures, etc. +.It Ic vmstat +Take over the entire display and show a (rather crowded) compendium +of statistics related to virtual memory usage, process scheduling, +device interrupts, system name translation cacheing, disk +.Tn I/O +etc. +.Pp +The upper left quadrant of the screen shows the number +of users logged in and the load average over the last one, five, +and fifteen minute intervals. +Below this line are statistics on memory utilization. +The first row of the table reports memory usage only among +active processes, that is processes that have run in the previous +twenty seconds. +The second row reports on memory usage of all processes. +The first column reports on the number of physical pages +claimed by processes. +The second column reports the number of physical pages that +are devoted to read only text pages. +The third and fourth columns report the same two figures for +virtual pages, that is the number of pages that would be +needed if all processes had all of their pages. +Finally the last column shows the number of physical pages +on the free list. +.Pp +Below the memory display is the disk usage display. +It reports the number of seeks, transfers, and number +of kilobyte blocks transferred per second averaged over the +refresh period of the display (by default, five seconds). +For some disks it also reports the average milliseconds per seek. +Note that the system only keeps statistics on at most four disks. +.Pp +Below the disk display is a list of the +average number of processes (over the last refresh interval) +that are runnable (`r'), in page wait (`p'), +in disk wait other than paging (`d'), +sleeping (`s'), and swapped out but desiring to run (`w'). +Below the queue length listing is a numerical listing and +a bar graph showing the amount of +system (shown as `='), user (shown as `>'), +nice (shown as `-'), and idle time (shown as ` '). +.Pp +At the bottom left are statistics on name translations. +It lists the number of names translated in the previous interval, +the number and percentage of the translations that were +handled by the system wide name translation cache, and +the number and percentage of the translations that were +handled by the per process name translation cache. +.Pp +Under the date in the upper right hand quadrant are statistics +on paging and swapping activity. +The first two columns report the average number of pages +brought in and out per second over the last refresh interval +due to page faults and the paging daemon. +The third and fourth columns report the average number of pages +brought in and out per second over the last refresh interval +due to swap requests initiated by the scheduler. +The first row of the display shows the average +number of disk transfers per second over the last refresh interval; +the second row of the display shows the average +number of pages transferred per second over the last refresh interval. +.Pp +Below the paging statistics is a line listing the average number of +total reclaims ('Rec'), +intransit blocking page faults (`It'), +swap text pages found in free list (`F/S'), +file system text pages found in free list (`F/F'), +reclaims from free list +pages freed by the clock daemon (`Fre'), +and sequential process pages freed (`SFr') +per second over the refresh interval. +.Pp +Below this line are statistics on the average number of +zero filled pages (`zf') and demand filled text pages (`xf') +per second over the refresh period. +The first row indicates the number of requests that were +resolved, the second row shows the number that were set up, +and the last row shows the percentage of setup requests that were +actually used. +Note that this percentage is usually less than 100%, +however it may exceed 100% if a large number of requests +are actually used long after they were set up during a +period when no new pages are being set up. +Thus this figure is most interesting when observed over +a long time period, such as from boot time +(see below on getting such a display). +.Pp +Below the page fill statistics is a column that +lists the average number of context switches (`Csw'), +traps (`Trp'; includes page faults), system calls (`Sys'), interrupts (`Int'), +characters output to DZ ports using +.No pseudo Ns -DMA +(`Pdm'), +network software interrupts (`Sof'), +page faults (`Flt'), pages scanned by the page daemon (`Scn'), +and revolutions of the page daemon's hand (`Rev') +per second over the refresh interval. +.Pp +Running down the right hand side of the display is a breakdown +of the interrupts being handled by the system. +At the top of the list is the total interrupts per second +over the time interval. +The rest of the column breaks down the total on a device +by device basis. +Only devices that have interrupted at least once since boot time are shown. +.Pp +The following commands are specific to the +.Ic vmstat +display;

The + AUTHENTICATION option is fairly well defined, and + an option number has been assigned to it. The + ENCRYPTION option is still in a state of flux; an + option number has NOT been assigned to it yet. + The code is provided in this release for experimental + and testing purposes. + + The telnet "send" command can now be used to send + do/dont/will/wont commands, with any telnet option + name. The rules for when do/dont/will/wont are sent + are still followed, so just because the user requests + that one of these be sent doesn't mean that it will + be sent... + + The telnet "getstatus" command no longer requires + that option printing be enabled to see the response + to the "DO STATUS" command. + + A -n flag has been added to telnetd to disable + keepalives. + + A new telnet command, "auth" has been added (if + AUTHENTICATE is defined). It has four sub-commands, + "status", "debug", "disable", "enable" and "help". + + A new telnet command, "encrypt" has been added (if + ENCRYPT is defined). It has many sub-commands: + "enable", "type", "start", "stop", "input", + "-input", "output", "-output", "status", "auto", + "verbose", "debug", and "help". + + An "rlogin" interface has been added. If the program + is named "rlogin", or the "-r" flag is given, then + an rlogin type of interface will be used. + ~. Terminates the session + ~ Suspend the session + ~^] Escape to telnet command mode + ~~ Pass through the ~. + BUG: If you type the rlogin escape character + in the middle of a line while in rlogin + mode, you cannot erase it or any characters + before it. Hopefully this can be fixed + in a future release... + + General changes: + + A "libtelnet.a" has now been created. This libraray + contains code that is common to both telnet and + telnetd. This is also where library routines that + are needed, but are not in the standard C library, + are placed. + + The makefiles have been re-done. All of the site + specific configuration information has now been put + into a single "Config.generic" file, in the top level + directory. Changing this one file will take care of + all three subdirectories. Also, to add a new/local + definition, a "Config.local" file may be created + at the top level; if that file exists, the subdirectories + will use that file instead of "Config.generic". + + Many 1-2 line functions in commands.c have been + removed, and just inserted in-line, or replaced + with a macro. + + Bug Fixes: + + The non-termio code in both telnet and telnetd was + setting/clearing CTLECH in the sg_flags word. This + was incorrect, and has been changed to set/clear the + LCTLECH bit in the local mode word. + + The SRCRT #define has been removed. If IP_OPTIONS + and IPPROTO_IP are defined on the system, then the + source route code is automatically enabled. + + The NO_GETTYTAB #define has been removed; there + is a compatability routine that can be built into + libtelnet to achive the same results. + + The server, telnetd, has been switched to use getopt() + for parsing the argument list. + + The code for getting the input/output speeds via + cfgetispeed()/cfgetospeed() was still not quite + right in telnet. Posix says if the ispeed is 0, + then it is really equal to the ospeed. + + The suboption processing code in telnet now has + explicit checks to make sure that we received + the entire suboption (telnetd was already doing this). + + The telnet code for processing the terminal type + could cause a core dump if an existing connection + was closed, and a new connection opened without + exiting telnet. + + Telnetd was doing a TCSADRAIN when setting the new + terminal settings; This is not good, because it means + that the tcsetattr() will hang waiting for output to + drain, and telnetd is the only one that will drain + the output... The fix is to use TCSANOW which does + not wait. + + Telnetd was improperly setting/clearing the ISTRIP + flag in the c_lflag field, it should be using the + c_iflag field. + + When the child process of telnetd was opening the + slave side of the pty, it was re-setting the EXTPROC + bit too early, and some of the other initialization + code was wiping it out. This would cause telnetd + to go out of linemode and into single character mode. + + One instance of leaving linemode in telnetd forgot + to send a WILL ECHO to the client, the net result + would be that the user would see double character + echo. + + If the MODE was being changed several times very + quickly, telnetd could get out of sync with the + state changes and the returning acks; and wind up + being left in the wrong state. + +September 14, 1990: + + Switch the client to use getopt() for parsing the + argument list. The 4.3Reno getopt.c is included for + systems that don't have getopt(). + + Use the posix _POSIX_VDISABLE value for what value + to use when disabling special characters. If this + is undefined, it defaults to 0x3ff. + + For non-termio systems, TIOCSETP was being used to + change the state of the terminal. This causes the + input queue to be flushed, which we don't want. This + is now changed to TIOCSETN. + + Take out the "#ifdef notdef" around the code in the + server that generates a "sync" when the pty oputput + is flushed. The potential problem is that some older + telnet clients may go into an infinate loop when they + receive a "sync", if so, the server can be compiled + with "NO_URGENT" defined. + + Fix the client where it was setting/clearing the OPOST + bit in the c_lflag field, not the c_oflag field. + + Fix the client where it was setting/clearing the ISTRIP + bit in the c_lflag field, not the c_iflag field. (On + 4.3Reno, this is the ECHOPRT bit in the c_lflag field.) + The client also had its interpretation of WILL BINARY + and DO BINARY reversed. + + Fix a bug in client that would cause a core dump when + attempting to remove the last environment variable. + + In the client, there were a few places were switch() + was being passed a character, and if it was a negative + value, it could get sign extended, and not match + the 8 bit case statements. The fix is to and the + switch value with 0xff. + + Add a couple more printoption() calls in the client, I + don't think there are any more places were a telnet + command can be received and not printed out when + "options" is on. + + A new flag has been added to the client, "-a". Currently, + this just causes the USER name to be sent across, in + the future this may be used to signify that automatic + authentication is requested. + + The USER variable is now only sent by the client if + the "-a" or "-l user" options are explicity used, or + if the user explicitly asks for the "USER" environment + variable to be exported. In the server, if it receives + the "USER" environment variable, it won't print out the + banner message, so that only "Password:" will be printed. + This makes the symantics more like rlogin, and should be + more familiar to the user. (People are not used to + getting a banner message, and then getting just a + "Password:" prompt.) + + Re-vamp the code for starting up the child login + process. The code was getting ugly, and it was + hard to tell what was really going on. What we + do now is after the fork(), in the child: + 1) make sure we have no controlling tty + 2) open and initialize the tty + 3) do a setsid()/setpgrp() + 4) makes the tty our controlling tty. + On some systems, #2 makes the tty our controlling + tty, and #4 is a no-op. The parent process does + a gets rid of any controlling tty after the child + is fork()ed. + + Use the strdup() library routine in telnet, instead + of the local savestr() routine. If you don't have + strdup(), you need to define NO_STRDUP. + + Add support for ^T (SIGINFO/VSTATUS), found in the + 4.3Reno distribution. This maps to the AYT character. + You need a 4-line bugfix in the kernel to get this + to work properly: + + > *** tty_pty.c.ORG Tue Sep 11 09:41:53 1990 + > --- tty_pty.c Tue Sep 11 17:48:03 1990 + > *************** + > *** 609,613 **** + > if ((tp->t_lflag&NOFLSH) == 0) + > ttyflush(tp, FREAD|FWRITE); + > ! pgsignal(tp->t_pgrp, *(unsigned int *)data); + > return(0); + > } + > --- 609,616 ---- + > if ((tp->t_lflag&NOFLSH) == 0) + > ttyflush(tp, FREAD|FWRITE); + > ! pgsignal(tp->t_pgrp, *(unsigned int *)data, 1); + > ! if ((*(unsigned int *)data == SIGINFO) && + > !

The telnet/Source + directory is now gone, and all the source that was in + telnet/Source is now just in the telnet directory. + + Seperate makefile for each system are now gone. There + are two makefiles, Makefile and Makefile.generic. + The "Makefile" has the definitions for the various + system, and "Makefile.generic" does all the work. + There is a variable called "WHAT" that is used to + specify what to make. For example, in the telnet + directory, you might say: + make 4.4bsd WHAT=clean + to clean out the directory. + + Add support for the ENVIRON and XDISPLOC options. + In order for the server to work, login has to have + the "-p" option to preserve environment variables. + + Add the SOFT_TAB and LIT_ECHO modes in the LINEMODE support. + + Add the "-l user" option to command line and open command + (This is passed through the ENVIRON option). + + Add the "-e" command line option, for setting the escape + character. + + Add the "-D", diagnostic, option to the server. This allows + the server to print out debug information, which is very + useful when trying to debug a telnet that doesn't have any + debugging ability. + + Turn off the literal next character when not in LINEMODE. + + Don't recognize ^Y locally, just pass it through. + + Make minor modifications for Sun4.0 and Sun4.1 + + Add support for both FORW1 and FORW2 characters. The + telnet escpape character is set to whichever of the + two is not being used. If both are in use, the escape + character is not set, so when in linemode the user will + have to follow the escape character with a or + + +The following TELNET options are supported: + + LINEMODE: + The LINEMODE option is supported as per RFC1116. The + FORWARDMASK option is not currently supported. + + BINARY: The client has the ability to turn on/off the BINARY + option in each direction. Turning on BINARY from + server to client causes the LITOUT bit to get set in + the terminal driver on both ends, turning on BINARY + from the client to the server causes the PASS8 bit + to get set in the terminal driver on both ends. + + TERMINAL-TYPE: + This is supported as per RFC1091. On the server side, + when a terminal type is received, termcap/terminfo + is consulted to determine if it is a known terminal + type. It keeps requesting terminal types until it + gets one that it recongnizes, or hits the end of the + list. The server side looks up the entry in the + termcap/terminfo data base, and generates a list of + names which it then passes one at a time to each + request for a terminal type, duplicating the last + entry in the list before cycling back to the beginning. + + NAWS: The Negotiate about Window Size, as per RFC 1073. + + TERMINAL-SPEED: + Implemented as per RFC 1079 + + TOGGLE-FLOW-CONTROL: + Implemented as per RFC 1080 + + TIMING-MARK: + As per RFC 860 + + SGA: As per RFC 858 + + ECHO: As per RFC 857 + + STATUS: + The server will send its current status upon + request.

This causes the +BINARY option to be negotiated on output. +.It Fl S Ar tos +Sets the IP type-of-service (TOS) option for the telnet +connection to the value +.Ar tos, +which can be a numeric TOS value +or, on systems that support it, a symbolic +TOS name found in the /etc/iptos file. +.It Fl X Ar atype +Disables the +.Ar atype +type of authentication. +.It Fl a +Attempt automatic login. +Currently, this sends the user name via the +.Ev USER +variable +of the +.Ev ENVIRON +option if supported by the remote system. +The name used is that of the current user as returned by +.Xr getlogin 2 +if it agrees with the current user ID, +otherwise it is the name associated with the user ID. +.It Fl c +Disables the reading of the user's +.Pa \&.telnetrc +file. (See the +.Ic toggle skiprc +command on this man page.) +.It Fl d +Sets the initial value of the +.Ic debug +toggle to +.Dv TRUE +.It Fl e Ar escape char +Sets the initial +.Nm +.Nm telnet +escape character to +.Ar escape char. +If +.Ar escape char +is omitted, then +there will be no escape character. +.It Fl f +If Kerberos V5 authentication is being used, the +.Fl f +option allows the local credentials to be forwarded to the remote system. +.It Fl k Ar realm +If Kerberos authentication is being used, the +.Fl k +option requests that telnet obtain tickets for the remote host in +realm realm instead of the remote host's realm, as determined +by +.Xr krb_realmofhost 3 . +.It Fl l Ar user +When connecting to the remote system, if the remote system +understands the +.Ev ENVIRON +option, then +.Ar user +will be sent to the remote system as the value for the variable USER. +This option implies the +.Fl a +option. +This option may also be used with the +.Ic open +command. +.It Fl n Ar tracefile +Opens +.Ar tracefile +for recording trace information. +See the +.Ic set tracefile +command below. +.It Fl r +Specifies a user interface similar to +.Xr rlogin 1 . +In this +mode, the escape character is set to the tilde (~) character, +unless modified by the -e option. +.It Fl x +Turns on encryption of the data stream if possible. This +option is not available outside of the United States and +Canada. +.It Ar host +Indicates the official name, an alias, or the Internet address +of a remote host. +.It Ar port +Indicates a port number (address of an application). If a number is +not specified, the default +.Nm telnet +port is used. +.El +.Pp +When in rlogin mode, a line of the form ~. disconnects from the +remote host; ~ is the telnet escape character. +Similarly, the line ~^Z suspends the telnet session. +The line ~^] escapes to the normal telnet escape prompt. +.Pp +Once a connection has been opened, +.Nm telnet +will attempt to enable the +.Dv TELNET LINEMODE +option. +If this fails, then +.Nm telnet +will revert to one of two input modes: +either \*(Lqcharacter at a time\*(Rq +or \*(Lqold line by line\*(Rq +depending on what the remote system supports. +.Pp +When +.Dv LINEMODE +is enabled, character processing is done on the +local system, under the control of the remote system. When input +editing or character echoing is to be disabled, the remote system +will relay that information. The remote system will also relay +changes to any special characters that happen on the remote +system, so that they can take effect on the local system. +.Pp +In \*(Lqcharacter at a time\*(Rq mode, most +text typed is immediately sent to the remote host for processing. +.Pp +In \*(Lqold line by line\*(Rq mode, all text is echoed locally, +and (normally) only completed lines are sent to the remote host. +The \*(Lqlocal echo character\*(Rq (initially \*(Lq^E\*(Rq) may be used +to turn off and on the local echo +(this would mostly be used to enter passwords +without the password being echoed). +.Pp +If the +.Dv LINEMODE +option is enabled, or if the +.Ic localchars +toggle is +.Dv TRUE +(the default for \*(Lqold line by line\*(Lq; see below), +the user's +.Ic quit , +.Ic intr , +and +.Ic flush +characters are trapped locally, and sent as +.Tn TELNET +protocol sequences to the remote side. +If +.Dv LINEMODE +has ever been enabled, then the user's +.Ic susp +and +.Ic eof +are also sent as +.Tn TELNET +protocol sequences, +and +.Ic quit +is sent as a +.Dv TELNET ABORT +instead of +.Dv BREAK +There are options (see +.Ic toggle +.Ic autoflush +and +.Ic toggle +.Ic autosynch +below) +which cause this action to flush subsequent output to the terminal +(until the remote host acknowledges the +.Tn TELNET +sequence) and flush previous terminal input +(in the case of +.Ic quit +and +.Ic intr ) . +.Pp +While connected to a remote host, +.Nm telnet +command mode may be entered by typing the +.Nm telnet +\*(Lqescape character\*(Rq (initially \*(Lq^]\*(Rq). +When in command mode, the normal terminal editing conventions are available. +.Pp +The following +.Nm telnet +commands are available. +Only enough of each command to uniquely identify it need be typed +(this is also true for arguments to the +.Ic mode , +.Ic set , +.Ic toggle , +.Ic unset , +.Ic slc , +.Ic environ , +and +.Ic display +commands). +.Pp +.Bl -tag -width "mode type" +.It Ic auth Ar argument ... +The auth command manipulates the information sent through the +.Dv TELNET AUTHENTICATE +option.

The put command causes the remote +.Ux +system to run the command string ``cat > 'to''', while +.Nm tip +sends it the ``from'' +file. If the ``to'' file isn't specified the ``from'' file name is used. +This command is actually a +.Ux +specific version of the ``~>'' command. +.It Ic \&~t Ar from Op Ar to +Take a file from a remote +.Ux +host. +As in the put command the ``to'' file +defaults to the ``from'' file name if it isn't specified. +The remote host +executes the command string ``cat 'from';echo ^A'' to send the file to +.Nm tip . +.It Ic \&~| +Pipe the output from a remote command to a local +.Ux +process. +The command string sent to the local +.Ux +system is processed by the shell. +.It Ic \&~$ +Pipe the output from a local +.Ux +process to the remote host. +The command string sent to the local +.Ux +system is processed by the shell. +.It Ic \&~C +Fork a child process on the local system to perform special protocols +such as \s-1XMODEM\s+1.

If this value is not suitable, the baud rate +to be used may be specified on the command line, e.g. +.Ql "tip -300 mds" . +.Pp +When +.Nm tip +establishes a connection it sends out a +connection message to the remote system; the default value, if any, +is defined in +.Pa /etc/remote +(see +.Xr remote 5 ) . +.Pp +When +.Nm tip +prompts for an argument (e.g. during setup of +a file transfer) the line typed may be edited with the standard +erase and kill characters. A null line in response to a prompt, +or an interrupt, will abort the dialogue and return you to the +remote machine. +.Pp +.Nm Tip +guards against multiple users connecting to a remote system +by opening modems and terminal lines with exclusive access, +and by honoring the locking protocol used by +.Xr uucico 8 . +.Pp +During file transfers +.Nm tip +provides a running count of the number of lines transferred. +When using the ~> and ~< commands, the ``eofread'' and ``eofwrite'' +variables are used to recognize end-of-file when reading, and +specify end-of-file when writing (see below). File transfers +normally depend on tandem mode for flow control. If the remote +system does not support tandem mode, ``echocheck'' may be set +to indicate +.Nm tip +should synchronize with the remote system on the echo of each +transmitted character. +.Pp +When +.Nm tip +must dial a phone number to connect to a system it will print +various messages indicating its actions. +.Nm Tip +supports the +.Tn DEC DN Ns-11 +and +Racal-Vadic 831 auto-call-units; +the +.Tn DEC DF Ns \&02 +and +.Tn DF Ns \&03 , +Ventel 212+, Racal-Vadic 3451, and +Bizcomp 1031 and 1032 integral call unit/modems. +.Ss VARIABLES +.Nm Tip +maintains a set of +.Ar variables +which control its operation. +Some of these variables are read-only to normal users (root is allowed +to change anything of interest). Variables may be displayed +and set through the ``s'' escape. The syntax for variables is patterned +after +.Xr vi 1 +and +.Xr Mail 1 . +Supplying ``all'' +as an argument to the set command displays all variables readable by +the user. Alternatively, the user may request display of a particular +variable by attaching a `?' to the end. For example ``escape?'' +displays the current escape character. +.Pp +Variables are numeric, string, character, or boolean values. Boolean +variables are set merely by specifying their name; they may be reset +by prepending a `!' to the name. Other variable types are set by +concatenating an `=' and the value. The entire assignment must not +have any blanks in it. A single set command may be used to interrogate +as well as set a number of variables. +Variables may be initialized at run time by placing set commands +(without the ``~s'' prefix in a file +.Pa .tiprc +in one's home directory). The +.Fl v +option causes +.Nm tip +to display the sets as they are made. +Certain common variables have abbreviations. +The following is a list of common variables, +their abbreviations, and their default values. +.Bl -tag -width Ar +.It Ar beautify +(bool) Discard unprintable characters when a session is being scripted; +abbreviated +.Ar be . +.It Ar baudrate +(num) The baud rate at which the connection was established; +abbreviated +.Ar ba . +.It Ar dialtimeout +(num) When dialing a phone number, the time (in seconds) +to wait for a connection to be established; abbreviated +.Ar dial . +.It Ar echocheck +(bool) Synchronize with the remote host during file transfer by +waiting for the echo of the last character transmitted; default is +.Ar off . +.It Ar eofread +(str) The set of characters which signify an end-of-transmission +during a ~< file transfer command; abbreviated +.Ar eofr . +.It Ar eofwrite +(str) The string sent to indicate end-of-transmission during +a ~> file transfer command; abbreviated +.Ar eofw . +.It Ar eol +(str) The set of characters which indicate an end-of-line. +.Nm Tip +will recognize escape characters only after an end-of-line. +.It Ar escape +(char) The command prefix (escape) character; abbreviated +.Ar es ; +default value is `~'. +.It Ar exceptions +(str) The set of characters which should not be discarded +due to the beautification switch; abbreviated +.Ar ex ; +default value is ``\et\en\ef\eb''. +.It Ar force +(char) The character used to force literal data transmission; +abbreviated +.Ar fo ; +default value is `^P'. +.It Ar framesize +(num) The amount of data (in bytes) to buffer between file system +writes when receiving files; abbreviated +.Ar fr . +.It Ar host +(str) The name of the host to which you are connected; abbreviated +.Ar ho . +.It Ar prompt +(char) The character which indicates an end-of-line on the remote +host; abbreviated +.Ar pr ; +default value is `\en'.

This version will now deal with CICS and VM/XA on the IBM +side, and with SunOS 4.0 on Sun 3's and Sun 4's. + +This version has been tested on various versions of BSD Unix, including +4.2 and 4.3 (but there are never vanilla versions) and the post-4.3 systems +running at Berkeley. It has been tested on CCI's, Vaxen, Sun 3's and Sun 4's. +However, it doesn't necessarily work on all systems (nor has the testing +been as intensive as one might like). + +This version should build on any Berkeley-derived system. + +There are two alternate make files: ./makefile_4.2 and telnet/Makefile_ultrix. + +**** Try ./makefile_4.2 if you get compile-time errors, or get + "multiply defined" messages for "_putchar" from the loader. + +**** Try telnet/Makefile_ultrix if your make(1) utility doesn't + support VPATH. Also try this makefile if your ld(1) doesn't + support the -r flag correctly. + +The bad news is that I've had to drop MS-DOS support. The good news here is +that there are various versions available for MS-DOS (from FTP Software in +Cambridge, Mass.; from IBM; from Excelan; and probably from others). The +hooks are still there, as well as some code to update the screen. However, +I just haven't had the time to produce a fully integrated version that would +"just make". I suspect that a future release may have MS-DOS support back +in it. + +There is no Mac support. Contact Peter DiCamillo at Brown University if +you need a Mac tn3270. + +The main code change in this version is to what used to be called "telnet.c". +This is now replaced with a version of telnet (substantially what appeared +in the "4.3tahoe" release from CSRG) which is broken into separate files. + +Here is an overview of the directory structure: + + api/ General library of function needed by API + (and, to some extent, by the rest of tn3270). + + arpa/ Location of "telnet.h" (for non-4.3 systems). + + ascii/ Routines necessary to handle the case of running + from an ASCII-oriented system (ie: unix). + + ctlr/ The main part of the emulator. Handles 3270 scan + codes, 3270 data stream, 3270 display codes, + and EBCDIC. Also, the internal API function + lives here. + + general/ Some general subroutines and data structures of + interest to the emulator only. + + sys_curses/ System-dependent code for a curses-based environment. + + sys_dos/ System-dependent code for an MS-DOS-base environment. + Remember that this is included for your developmental + needs (ie: it doesn't work). + + telnet/ Where the telnet portion of tn3720 is built. + + tools/ Various tools. Most of these are used during the + build process. One (prt3270) is a debugging tool. + One (mkmake.y) is quite horrible, and attempts to + transform Unix makefiles into PC makefiles. + + utilities/ The source for tnrecv, which receives files + (fairly slowly) from an IBM host. We don't + include the IBM side, because we really aren't + happy with very much of it (except that it does, + sometimes, work). Hopefully, when we get past + the beta stage we will have more robust (and + complete) code to share. + +The fact that system dependancies are isolated should make it easy +to port to other systems. I would like to hear about problems porting +to new areas. + +In the August, 1987 README file, the following appeared: + +> WHAT IS NOT IN THIS VERSION (sigh): + +> 1) We don't have a native X version yet. I am waiting for X version 11 +> (though this is mostly an excuse; I could have done version 10, +> but I haven't had the time). + +> 2) We don't process structured fields. + +> 3) We don't do 3270-style graphics (ala 3193, say). + +> The above three items WILL be in the next version, which should come +> along "any day now" (say 6 months) (but, they WON'T be in the production +> release of this version). + +The next piece of bad news is that none of the above have happened yet, +and I don't know when they might occur. diff --git a/usr.bin/tn3270/distribution/arpa/makefile b/usr.bin/tn3270/distribution/arpa/makefile new file mode 100644 index 0000000..2cf3bc0 --- /dev/null +++ b/usr.bin/tn3270/distribution/arpa/makefile @@ -0,0 +1,67 @@ +# @(#)makefile 8.1 (Berkeley) 6/6/93 + +# msdos versus unix defines +O = .o +#PC_O = .obj + +X = +#PC_X = .exe + +L = +#PC_L = -link + +CC = cc +#PC_CC = cl + +MV = mv +#PC_MV = rename + +RM = rm -f +#PC_RM= erase + +LINT_ARGS = +#PC_LINT_ARGS = -DLINT_ARGS + +DEBUG_FLAGS = -g +#PC_DEBUG_FLAGS = -Zi -Od + +AR = ar +AR1 = cr +AR2 = +AR3 = +#PC_AR = lib +#PC_AR1 = +#PC_AR2 = + +#PC_AR3 = ";" + +RANLIB = ranlib +#PC_RANLIB = echo "Done with " + +PRINT = lpr -p + +ALLC = +ALLH = telnet.h + +ALLPRINT = ${ALLH} ${ALLC} + +ALLSOURCE = ${ALLPRINT} makefile makefile.mak + +clean: + +sccsclean: + -sccs clean + -sccs get makefile + +action: + ${ACTION} + +print: + ${PRINT} ${ALLPRINT} + + +sourcelist: ${ALLSOURCE} + @for i in ${ALLSOURCE}; \ + do (echo ${DIRPATH}$$i); done + +.DEFAULT: + sccs get $< diff --git a/usr.bin/tn3270/distribution/arpa/telnet.h b/usr.bin/tn3270/distribution/arpa/telnet.h new file mode 100644 index 0000000..eeb72c2 --- /dev/null +++ b/usr.bin/tn3270/distribution/arpa/telnet.h @@ -0,0 +1,191 @@ +/*- + * Copyright (c) 1983, 1993 + * The Regents of the University of California.

As in the earlier posting, the bug can be fixed +by replacing the definitions of the nl() and nonl() macros in curses.h with: + +#define nl() (_tty.sg_flags |= CRMOD,_pfast = _rawmode,stty(_tty_ch, &_tty)) +#define nonl() (_tty.sg_flags &= ~CRMOD, _pfast = TRUE, stty(_tty_ch, &_tty)) + +- john nelson. + +P.S. I did reach someone at DEC who would listen (Thanks Chet!) My + understanding is that they have no plans to fix this bug, as curses + is now "owned" by some group in England, who is working on a port of the + terminfo curses for Ultrix 2.4. I'm just pissed that my bug reports + submitted for Ultrix 1.2 and 2.0 were ignored. diff --git a/usr.bin/tn3270/distribution/utilities/adm3a.keys b/usr.bin/tn3270/distribution/utilities/adm3a.keys new file mode 100644 index 0000000..4e65374 --- /dev/null +++ b/usr.bin/tn3270/distribution/utilities/adm3a.keys @@ -0,0 +1,78 @@ +1LSI ADM 3A Key Definitions for IBM 3277 Terminal Emulation 06/18/81 ++LSI ADM 3A Key Definitions for IBM 3277 Terminal Emulation 06/18/81 + + 3277 Key ADM Key(s) | 3277 Key LSI ADM 3A Key(s) + ======== ========== | ======== ==================== + | + Cursor Movement Keys | Command Keys ++______ ________ ____ _______ ____ + | + New Line Ctrl-N -or- | Enter Return + Home | Clear Ctrl-Z + Tab Ctrl-I | + Back Tab Ctrl-B | Program Function Keys ++ _______ ________ ____ + Cursor Left Ctrl-H | + Cursor Right Ctrl-L | PF1 Esc 1 + Cursor Up Ctrl-K | PF2 Esc 2 + Cursor Down Ctrl-J -or- | PF3 Esc 3 + Line Feed | PF4 Esc 4 + Home Ctrl-@ | PF5 Esc 5 + | PF6 Esc 6 + | PF7 Esc 7 + Edit Control Keys | PF8 Esc 8 ++____ _______ ____ + | PF9 Esc 9 + Delete Char Ctrl-D -OR- Rub | PF10 Esc 0 + Erase EOF Ctrl-E | PF11 Esc Colon + Erase Input Ctrl-W | PF12 Esc Minus + Insert Mode Esc Space | PF13 Ctrl-F 1 3 + End Insert Esc Space | PF14 Ctrl-F 1 4 + Dup Ctrl-U | PF15 Ctrl-F 1 5 + Field Mark Ctrl-Y | PF16 Ctrl-F 1 6 + | PF17 Ctrl-F 1 7 + Series-1 Control Keys | PF18 Ctrl-F 1 8 ++________ _______ ____ + | PF19 Ctrl-F 1 9 + Reset After Error Ctrl-R | PF20 Ctrl-F 2 0 + Keyboard Unlock Ctrl-T | PF21 Ctrl-F 2 1 + Purge Input Buffer Ctrl-X | PF22 Ctrl-F 2 2 + Stop Output Ctrl-S | PF23 Ctrl-F 2 3 + Start Output Ctrl-Q | PF24 Ctrl-F 2 4 + Re-Display Screen Ctrl-V | + | Program Attention Keys ++ _______ _________ ____ + Miscellaneous 3277 Keys | ++_____________ ____ ____ + | PA1 Ctrl-P 1 + Cursor Select Esc Period | PA2 Ctrl-P 2 + Test Request (not supported) | PA3 Ctrl-P 3 + + Series 1 Local Editing Keys ++______ _ _____ _______ ____ + + Set Tab Stop Esc Semicolon + Clear (all) Tab Stops Esc Plus + Set Left Margin (New Line) Esc LeftParen + Set Home (Home) Esc Exclamation + Tab to Next Local Tab Stop Esc i (or Esc I) + Tab to Previous Local Tab Stop Esc b (or Esc B) + Indent (to Next Local Tab Stop - New Line) Esc l (or Esc L) + Undent (to Previous Local Tab Stop - New Line) Esc h (or Esc H) + + + Note: If the terminal hangs up, enter "Ctrl-H" and see if the + cursor moves.

For example, a 3270 has a key labeled +.B EEOF +which erases the contents of the current field from the +location of the cursor to the end. +In order to accomplish this function, +the terminal user and a program emulating a 3270 must +agree on what keys will be typed +to invoke the +.B EEOF +function. +.PP +The requirements for these sequences are: +.nf +.ta 4n 9n +.sp + 1) that the first character of the sequence be outside of the + standard ascii printable characters; +.sp + 2) that no sequence \fIbe\fR an initial part of another (although + sequences may \fIshare\fR initial parts). +.sp +.fi +.SH FORMAT +The file consists of entries for various keyboards. The first part +of an entry lists the names of the keyboards which use that entry. +These names will often be the same as in +.I /etc/termcap +(see +.IR termcap (5)); +however, note that often the terminals from various termcap entries will all +use the same +.I map3270 +entry; for example, both 925 and 925vb (for +925 with visual bells) would probably use the same +.I map3270 +entry. +Additionally, there are occasions when the terminal type defines +a window manager, and it will then be necessary to specify a +keyboard name (via the +.B KEYBD +environment variable) as the name of the entry. +After the names, separated by vertical bars (`|'), comes a left +brace (`{'); the definitions; and, finally, a right brace +(`}'). +.PP +Each definition consists of a reserved keyword (see list below) which +identifies the 3270 function (extended as defined below), followed +by an equal sign (`='), followed by the various ways to generate +this particular function, followed by a semi-colon (`;'). +Each way is a sequence of strings of +.I printable +ascii characters enclosed inside single quotes (`\(aa'); +various ways (alternatives) are separated by vertical bars (`|'). +.PP +Inside the single quotes, a few characters are special. +A caret +(`^') specifies that the next character is +the ``control'' character of whatever the character is. +So, `^a' +represents control-a, ie: hexadecimal 1 +(note that `^A' would generate the same code). +To generate +.B rubout +(DEL), +one enters `^?'. +To represent a control character inside a file +requires using the caret to represent a control sequence; +simply typing control-A will not work. +Note: the ctrl-caret sequence +(to generate a hexadecimal 1E) +is represented as `^^' (not `^\e^'). +.PP +In addition to the caret, a letter may be preceded by a backslash (`\e'). +Since this has little effect for most characters, +its use is usually not recommended. +For the case of a single quote (`\(aa'), the backslash +prevents that single quote from terminating the string. +For the case of a caret (`^'), the backslash prevents +the caret from having its special meaning. +To have the backslash be part of the string, it is necessary to +place two backslashes ('\e\e') in the file. +.PP +In addition, the following characters are special: +.sp +.nf +.in +0.5i +`\eE' means an escape character; +`\en' means newline; +`\et' means tab; +`\er' means carriage return. +.in -0.5i +.fi +.sp +It is not necessary for each character in a string +to be enclosed within single quotes. +`\eE\eE\eE' means three escape characters. +.PP +Comments, which may appear anywhere on a line, +begin with a hash mark (`#'), and terminate +at the end of that line. +However, comments cannot begin inside a quoted string; +a hash mark inside a quoted string has no special meaning. +.PP +.SH 3270 KEYS SUPPORTED +The following is the list of 3270 key names that are supported in this file. +Note that some of the keys don't really exist on a 3270. +In particular, the developers of this file have relied +extensively on the work at the Yale University Computer Center with +their 3270 emulator which runs in an IBM Series/1 front end. +The following list corresponds closely to the functions +that the developers of the Yale code offer in their product. +.sp +.B In the following list, the +.B starred ("*") +.B functions are not supported by +.IR tn3270 (1). +An unsupported function will cause +.IR tn3270(1) +to send a (possibly visual) bell sequence to the user's terminal. +.sp +.nf + 3270 Key Name Functional description + + (*)LPRT local print + DP dup character + FM field mark character + CURSEL cursor select + CENTSIGN EBCDIC cent sign + RESHOW redisplay the screen + EINP erase input + EEOF erase end of field + DELETE delete character + INSRT toggle insert mode + TAB field tab + BTAB field back tab + COLTAB column tab + COLBAK column back tab + INDENT indent one tab stop + UNDENT undent one tab stop + NL new line + HOME home the cursor + UP up cursor + DOWN down cursor + RIGHT right cursor + LEFT left cursor + SETTAB set a column tab + DELTAB delete a columntab + SETMRG set left margin + SETHOM set home position + CLRTAB clear all column tabs + (*)APLON apl on + (*)APLOFF apl off + (*)APLEND treat input as ascii + (*)PCON xon/xoff on + (*)PCOFF xon/xoff off + DISC disconnect (suspend) + (*)INIT new terminal type + (*)ALTK alternate keyboard dvorak + FLINP flush input + ERASE erase last character + WERASE erase last word + FERASE erase field + SYNCH we are in synch with the user + RESET reset key-unlock keyboard + MASTER_RESET reset, unlock and redisplay + (*)XOFF please hold output + (*)XON please give me output + ESCAPE enter telnet command mode + WORDTAB tab to beginning of next word + WORDBACKTAB tab to beginning of current/last word + WORDEND tab to end of current/next word + FIELDEND tab to last non-blank of current/next + unprotected (writable) field. + + PA1 program attention 1 + PA2 program attention 2 + PA3 program attention 3 + + CLEAR local clear of the 3270 screen + TREQ test request + ENTER enter key + + PFK1 program function key 1 + PFK2 program function key 2 + etc. etc. + PFK36 program function key 36 +.SH A SAMPLE ENTRY +The following entry is used by +tn3270(1) when unable to locate a reasonable version in the +user's environment and in /etc/map3270: +.sp +.nf + name { # actual name comes from TERM variable + clear = '^z';

+.Nm Tset +first determines the type of terminal that you are using. +This determination is done as follows, using the first terminal type found. +.sp +.Bl -bullet -compact -offset indent +.It +The +.Ar terminal +argument specified on the command line. +.It +The value of the +.Ev TERM +environmental variable. +.It +The terminal type associated with the standard error output device in the +.Pa /etc/ttys +file. +.It +The default terminal type, ``unknown''. +.El +.Pp +If the terminal type was not specified on the command-line, the +.Fl m +option mappings are then applied (see below for more information). +Then, if the terminal type begins with a question mark (``?''), the user is +prompted for confirmation of the terminal type. +An empty response confirms the type, or, another type can be entered to +specify a new type. +Once the terminal type has been determined, the termcap entry for the terminal +is retrieved. +If no termcap entry is found for the type, the user is prompted for another +terminal type. +.Pp +Once the termcap entry is retrieved, the window size, backspace, interrupt +and line kill characters (among many other things) are set and the terminal +and tab initialization strings are sent to the standard error output. +Finally, if the erase, interrupt and line kill characters have changed, +or are not set to their default values, their values are displayed to the +standard error output. +.Pp +When invoked as +.Nm reset , +.Nm tset +sets cooked and echo modes, turns off cbreak and raw modes, turns on +newline translation and resets any unset special characters to their +default values before doing the terminal initialization described above. +This is useful after a program dies leaving a terminal in a abnormal state. +Note, you may have to type +.Dq Li reset +(the line-feed character is normally control-J) to get the terminal +to work, as carriage-return may no longer work in the abnormal state. +Also, the terminal will often not echo the command. +.Pp +The options are as follows: +.Bl -tag -width flag +.It Fl +The terminal type is displayed to the standard output, and the terminal is +not initialized in any way. +.It Fl e +Set the erase character to +.Ar ch . +.It Fl I +Do not send the terminal or tab initialization strings to the terminal. +.It Fl i +Set the interrupt character to +.Ar ch . +.It Fl k +Set the line kill character to +.Ar ch . +.It Fl m +Specify a mapping from a port type to a terminal. +See below for more information. +.It Fl Q +Don't display any values for the erase, interrupt and line kill characters. +.It Fl r +Print the terminal type to the standard error output. +.It Fl S +Print the terminal type and the termcap entry to the standard output. +See the section below on setting the environment for details. +.It Fl s +Print the sequence of shell commands to initialize the environment variables +.Ev TERM +and +.Ev TERMCAP +to the standard output. +See the section below on setting the environment for details. +.El +.Pp +The arguments for the +.Fl e , +.Fl i +and +.Fl k +options may either be entered as actual characters or by using the +.Dq hat +notation, i.e. control-h may be specified as +.Dq Li ^H +or +.Dq Li ^h . +.Sh SETTING THE ENVIRONMENT +It is often desirable to enter the terminal type and information about +the terminal's capabilities into the shell's environment. +This is done using the +.Fl S +and +.Fl s +options. +.Pp +When the +.Fl S +option is specified, the terminal type and the termcap entry are written +to the standard output, separated by a space and without a terminating +newline. +This can be assigned to an array by +.Nm csh +and +.Nm ksh +users and then used like any other shell array. +.Pp +When the +.Fl s +option is specified, the commands to enter the information into the +shell's environment are written to the standard output. +If the +.Ev SHELL +environmental variable ends in ``csh'', the commands are for the +.Nm csh , +otherwise, they are for +.Xr sh . +Note, the +.Nm csh +commands set and unset the shell variable +.Dq noglob , +leaving it unset. +The following line in the +.Pa .login +or +.Pa .profile +files will initialize the environment correctly: +.Bd -literal -offset indent +eval \`tset -s options ... \` +.Ed +.Pp +To demonstrate a simple use of the +.Fl S +option, the following lines in the +.Pa .login +file have an equivalent effect: +.Bd -literal -offset indent +set noglob +set term=(`tset -S options ...`) +setenv TERM $term[1] +setenv TERMCAP "$term[2]" +unset term +unset noglob +.Ed +.Sh TERMINAL TYPE MAPPING +When the terminal is not hardwired into the system (or the current system +information is incorrect) the terminal type derived from the +.Pa /etc/ttys +file or the +.Ev TERM +environmental variable is often something generic like +.Dq network , +.Dq dialup , +or +.Dq unknown . +When +.Nm tset +is used in a startup script +.Pf ( Pa .profile +for +.Xr sh 1 +users or +.Pa .login +for +.Xr csh 1 +users) it is often desirable to provide information about the type of +terminal used on such ports. +The purpose of the +.Fl m +option is to +.Dq map +from some set of conditions to a terminal type, that is, to +tell +.Nm tset +``If I'm on this port at a particular speed, guess that I'm on that +kind of terminal''. +.Pp +The argument to the +.Fl m +option consists of an optional port type, an optional operator, an optional +baud rate specification, an optional colon (``:'') character and a terminal +type. +The port type is a string (delimited by either the operator or the colon +character). +The operator may be any combination of: +.Dq Li \&> , +.Dq Li \&< , +.Dq Li \&@ , +and +.Dq Li \&! ; +.Dq Li \&> +means greater than, +.Dq Li \&< +means less than, +.Dq Li \&@ +means equal to +and +.Dq Li \&! +inverts the sense of the test. +The baud rate is specified as a number and is compared with the speed +of the standard error output (which should be the control terminal). +The terminal type is a string. +.Pp +If the terminal type is not specified on the command line, the +.Fl m +mappings are applied to the terminal type. +If the port type and baud rate match the mapping, the terminal type specified +in the mapping replaces the current type. +If more than one mapping is specified, the first applicable mapping is used. +.Pp +For example, consider the following mapping: +.Dq Li dialup>9600:vt100 . +The port type is +.Dq Li dialup , +the operator is +.Dq Li > , +the baud rate specification is +.Dq Li 9600 , +and the terminal type is +.Dq Li vt100 . +The result of this mapping is to specify that if the terminal type is +.Dq Li dialup , +and the baud rate is greater than 9600 baud, a terminal type of +.Dq Li vt100 +will be used. +.Pp +If no port type is specified, the terminal type will match any port type, +for example, +.Dq Li -m dialup:vt100 -m :?xterm +will cause any dialup port, regardless of baud rate, to match the terminal +type +.Dq Li vt100 , +and any non-dialup port type to match the terminal type +.Dq Li ?xterm . +Note, because of the leading question mark, the user will be +queried on a default port as to whether they are actually using an +.Ar xterm +terminal. +.Pp +No whitespace characters are permitted in the +.Fl m +option argument. +Also, to avoid problems with metacharacters, it is suggested that the entire +.Fl m +option argument be placed within single quote characters, and that +.Nm csh +users insert a backslash character (``\e'') before any exclamation +marks (``!''). +.Sh ENVIRONMENT +The +.Nm tset

On dialout modem control is disabled +and there is no getty process. +.PP +This program must be run setuid to root. +.PP +.I keyword +is chosen from the list: +.I disable +or +.IR dialout , +to condition a line for dialout; +and +.I enable +or +.IR dialin , +to condition a line for dialin. +.PP +When the line is conditioned for dialing out, the login name of the real uid +of the process is placed in /etc/utmp in capitals. +This declares that the line is in use and acts as an additional locking +mechanism. +.I Acucntrl +will refuse to act if the /etc/utmp entry for the line is not null, +is not the the user's login name (capitalized or not), +and if the process is not running as the superuser. +The last condition is to allow the superuser to clear the state of the line. +.PP +Turning modem control on or off is handled by poking into /dev/kmem. +It is currently implemented for dz, dh, and dmf lines. +.PP +Under 4.2 BSD the program will also refuse to disable a line if carrier is +sensed on it. This is to avoid the dead period where someone has just dialed +in and made the connection but has not yet logged in. +.PP +.I Ttyline +can be either of the form tty* or /dev/tty*. +Enabling/disabling a line whose name does not begin with ttyd? is prohibited +unless the real uid of the process is 0 or if the login name corresponding to +the real uid is uucp.

Unfortunately this +ioctl is not implemented in the vanilla 4.2 BSD dh driver even though the +dz and dmf drivers use an emulation of the DH11's modem control bits. This +has been fixed here. +.PP +Some time (currently 2 seconds) is required between disabling modem control +and opening the device. This is probably because of a race with getty whose +open is finally being allowed to complete. This time interval may not be +enough on a loaded system. Because of this problem and the above problem with +the dh driver there is deliberately no error message given when the TIOCMGET +ioctl fails. +.PP +Previously there were similar synchronization problems with the init process. +When dialins are disabled the capitalized name of the process cannot be posted +into /etc/utmp until init has finished clearing /etc/utmp. However one does +not know how long that will take, and, on a loaded system, it can take quite +a while. This was solved by the strategy of 1) posting the name, 2) poking +init, 3) going into a loop where the process repeatedly waits a second and +checks whether the entry has been cleared from /etc/utmp, and 4) posting the +name again. diff --git a/usr.bin/uucp/acucntrl/acucntrl.c b/usr.bin/uucp/acucntrl/acucntrl.c new file mode 100644 index 0000000..deba6ba --- /dev/null +++ b/usr.bin/uucp/acucntrl/acucntrl.c @@ -0,0 +1,814 @@ +/*- + * Copyright (c) 1985, 1986, 1993 + * The Regents of the University of California.

This +produces output which is neither invertible or precise, but does +represent a minimum of change to the input. It is similar to +.Dq Li cat -v . +.It Fl c +Request a format which displays a small subset of the +non-printable characters using C-style backslash sequences. +.It Fl F +Causes +.Nm vis +to fold output lines to foldwidth columns (default 80), like +.Xr fold 1 , +except +that a hidden newline sequence is used, (which is removed +when inverting the file back to its original form with +.Xr unvis 1 ) . +If the last character in the encoded file does not end in a newline, +a hidden newline sequence is appended to the output. +This makes +the output usable with various editors and other utilities which +typically don't work with partial lines. +.It Fl f +Same as +.Fl F . +.It Fl l +Mark newlines with the visible sequence +.Ql \e$ , +followed by the newline. +.It Fl n +Turns off any encoding, except for the fact that backslashes are +still doubled and hidden newline sequences inserted if +.Fl f +or +.Fl F +is selected. When combined with the +.Fl f +flag, +.Nm vis +becomes like +an invertible version of the +.Xr fold 1 +utility. That is, the output +can be unfolded by running the output through +.It Fl o +Request a format which displays non-printable characters as +an octal number, \eddd. +.It Fl s +Only characters considered unsafe to send to a terminal are encoded. +This flag allows backspace, bell, and carriage return in addition +to the default space, tab and newline. +.Xr unvis 1 . +.It Fl t +Tabs are also encoded. +.It Fl w +White space (space-tab-newline) is also encoded. +.El +.Sh SEE ALSO +.Xr unvis 1 , +.Xr vis 3 +.Sh HISTORY +The +.Nm +command appears in +.Bx 4.4 . diff --git a/usr.bin/vis/vis.c b/usr.bin/vis/vis.c new file mode 100644 index 0000000..94c9d41 --- /dev/null +++ b/usr.bin/vis/vis.c @@ -0,0 +1,173 @@ +/*- + * Copyright (c) 1989, 1993 + * The Regents of the University of California.

Windows are opened by calling wwopen(). +Wwwrite() is the primitive for writing to windows. Wwputc(), wwputs(), +and wwprintf() are also supported. Some of the outputs to windows are +delayed. Wwupdate() updates the terminal to match the internal screen +buffer. Wwspawn() spawns a child process on the other end of a window, +with its environment tailored to the window. Visible windows are +doubly linked in the order of their overlap. Wwadd() inserts a window +into the list at a given place. Wwdelete() deletes it. Windows not in +the list are not visible, though wwwrite() still works. Window was +written before the days of X and Sunview, so some of the terminology +is not standard. + + Most functions return -1 on error. Wwopen() returns the null +pointer. An error number is saved in wwerrno. Wwerror() returns an +error string based on wwerrno suitable for printing. + + The terminal drivers perform all output to the physical terminal, +including special functions like character and line insertion and +deletion. The window package keeps a list of known terminals. At +initialization time, the terminal type is matched against the list to +find the right terminal driver to use. The last driver, the generic +driver, matches all terminals and uses the termcap database. The +interface between the window package the terminal driver is the `tt' +structure. It contains pointers to functions to perform special +functions and terminal output, as well as flags about the +characteristics of the terminal. Most of these ideas are borrowed +from the Maryland window package, which in turn is based on Goslin's +Emacs. + + The IO system is semi-synchronous. Terminal input is signal +driven, and everything else is done synchronously with a single +select(). It is roughly event-driven, though not in a clean way. + + Normally, in both conversation mode and command mode, window +sleeps in a select() in wwiomux() waiting for data from the +pseudo-terminals. At the same time, terminal input causes SIGIO which +is caught by wwrint(). The select() returns when at least one of the +pseudo-terminals becomes ready for reading. + + Wwrint() is the interrupt handler for tty input. It reads input +into a linear buffer accessed through four pointers: + + +-------+--------------+----------------+ + | empty | data | empty | + +-------+--------------+----------------+ + ^ ^ ^ ^ + | | | | + wwib wwibp wwibq wwibe + +Wwrint() appends characters at the end and increments wwibq (*wwibq++ += c), and characters are taken off the buffer at wwibp using the +wwgetc() and wwpeekc() macros. As is the convention in C, wwibq +and wwibe point to one position beyond the end. In addition, +wwrint() will do a longjmp(wwjmpbuf) if wwsetjmp is true. This is +used by wwiomux() to interrupt the select() which would otherwise +resume after the interrupt. (Actually, I hear this is not true, +but the longjmp feature is used to avoid a race condition as well. +Anyway, it means I didn't have to depend on a feature in a +daily-changing kernel, but that's another story.) The macro +wwinterrupt() returns true if the input buffer is non-empty. +Wwupdate(), wwwrite(), and wwiomux() check this condition and will +return at the first convenient opportunity when it becomes true. +In the case of wwwrite(), the flag ww_nointr in the window structure +overrides this. This feature allows the user to interrupt lengthy +outputs safely. The structure of the input buffer is designed to +avoid race conditions without blocking interrupts. + + Actually, wwsetjmp and wwinterrupt() are part of a software +interrupt scheme used by the two interrupt catchers wwrint() and +wwchild(). Asserting the interrupt lets the synchronous parts of +the program know that there's an interesting asynchronous condition +(i.e., got a keyboard character, or a child process died) that they +might want to process before anything else. The synchronous routines +can check for this condition with wwinterrupt() or by arranging +that a longjmp() be done. + + Wwiomux() copies pseudo-terminal output into their corresponding +windows. Without anything to do, it blocks in a select(), waiting for +read ready on pseudo-terminals. Reads are done into per-window buffers +in the window structures. When there is at least one buffer non-empty, +wwiomux() finds the top most of these windows and writes it using +wwwrite(). Then the process is repeated. A non-blocking select() is +done after a wwwrite() to pick up any output that may have come in +during the write, which may take a long time. Specifically, we use +this to stop output or flush buffer when a pseudo-terminal tells us to +(we use pty packet mode). The select() blocks only when all of the +windows' buffers are empty. A wwupdate() is done prior to this, which +is the only time the screen is guaranteed to be completely up to date. +Wwiomux() loops until wwinterrupt() becomes true. + + The top level routine for all this is mloop(). In conversation +mode, it simply calls wwiomux(), which only returns when input is +available. The input buffer is then written to the pseudo-terminal of +the current window. If the escape character is found in the input, +command mode is entered. Otherwise, the process is repeated. In +command mode, control is transferred to docmd() which returns only when +conversation mode is reentered. Docmd() and other command processing +routines typically wait for input in a loop: + + while (wwpeekc() < 0) + wwiomux(); + +When the loop terminates, wwgetc() is used to read the input buffer. + + Output to the physical terminal is handled by the lowest level +routines of the window package, in the files ttoutput.c and tt.h. The +standard IO package is not used, to get better control over buffering +and to use non-blocking reads in wwrint(). The buffer size is set to +approximately one second of output time, based on the baudrate. + + The result of all this complexity is faster response time, +especially in output stopping and flushing. Wwwrite() checks +wwinterrupt() after every line. It also calls wwupdate() for each line +it writes. The output buffer is limited to one second of output time. +Thus, there is usually only a delay of one to two lines plus one second +after a ^C or ^S. Also, commands that produce lengthy output can be +aborted without actually showing all of it on the terminal. (Try the +'?' command followed by escape immediately.) diff --git a/usr.bin/window/alias.h b/usr.bin/window/alias.h new file mode 100644 index 0000000..ea63b49 --- /dev/null +++ b/usr.bin/window/alias.h @@ -0,0 +1,52 @@ +/* + * Copyright (c) 1983, 1993 + * The Regents of the University of California.

Its size and +position can be changed by the user at any time. Processes +communicate with their window in the same way they normally +interact with a terminal\-through their standard input, output, +and diagnostic file descriptors. The window program handles the +details of redirecting input and output to and from the +windows. At any one time, only one window can receive +input from the keyboard, but all windows can simultaneously send output +to the display. +.Pp +When +.Nm window +starts up, the commands (see long commands below) +contained in the file +.Pa .windowrc +in the user's home directory are +executed. If it does not exist, two equal sized windows spanning +the terminal screen are created by default. +.Pp +The command line options are +.Bl -tag -width Fl +.It Fl t +Turn on terse mode (see +.Ic terse +command below). +.It Fl f +Fast. Don't perform any startup action. +.It Fl d +Ignore +.Pa .windowrc +and create the two default +windows instead. +.It Fl e Ar escape-char +Set the escape character to +.Ar escape-char . +.Ar Escape-char +can be a single character, or in the form +.Ic ^X +where +.Ar X +is any character, meaning +.No control\- Ns Ar X . +.It Fl c Ar command +Execute the string +.Ar command +as a long command (see below) +before doing anything else. +.El +.Pp +Windows can overlap and are framed as necessary. Each window +is named by one of the digits ``1'' to ``9''. This one-character +identifier, as well as a user definable label string, are displayed +with the window on the top edge of its frame. A window can be +designated to be in the +.Ar foreground , +in which case it will always be +on top of all normal, non-foreground windows, and can be covered +only by other foreground windows. A window need not be completely +within the edges of the terminal screen. Thus a large window +(possibly larger than the screen) may be positioned to show only +a portion of its full size. +.Pp +Each window has a cursor and a set of control functions. Most intelligent +terminal operations such as line and +character deletion and insertion are supported. Display modes +such as underlining and reverse video are available if they are +supported by the terminal. In addition, +similar to terminals with multiple pages of memory, +each window has a text buffer which can have more lines than the window +itself. +.Ss Process Environment +With each newly created window, a shell program is spawned with its +process environment tailored to that window. Its standard input, +output, and diagnostic file descriptors are bound to one end of either +a pseudo-terminal +.Xr (pty 4 ) +or a +.Ux +domain socket +.Xr (socketpair 4 ) . +If a pseudo-terminal is used, then its special +characters and modes (see +.Xr stty 1 ) +are copied from the physical +terminal. A +.Xr termcap 5 +entry tailored to this window is created +and passed as environment +.Xr (environ 5 ) +variable +.Ev TERMCAP . +The termcap entry contains the window's size and +characteristics as well as information from the physical terminal, +such as the existence of underline, reverse video, and other display +modes, and the codes produced by the terminal's function keys, +if any. In addition, the window size attributes of the pseudo-terminal +are set to reflect the size of this window, and updated whenever +it is changed by the user. In particular, the editor +.Xr vi 1 +uses +this information to redraw its display. +.Ss Operation +During normal execution, +.Nm window +can be in one of two states: +conversation mode and command mode. In conversation mode, the +terminal's real cursor is placed at the cursor position of a particular +window--called the current window--and input from the keyboard is sent +to the process in that window. The current window is always +on top of all other windows, except those in foreground. In addition, +it is set apart by highlighting its identifier and label in reverse video. +.Pp +Typing +.Nm window Ns 's +escape character (normally +.Ic ^P ) +in conversation +mode switches it into command mode. In command mode, the top line of +the terminal screen becomes the command prompt window, and +.Nm window +interprets input from the keyboard as commands to manipulate windows. +.Pp +There are two types of commands: short commands are usually one or two +key strokes; long commands are strings either typed by the user in the +command window (see the +.Dq Ic \&: +command below), or read from a file (see +.Ic source +below). +.Ss Short Commands +Below, +.Ar \&# +represents one of the digits ``1'' to ``9'' +corresponding to the windows 1 to 9. +.Ic ^X +means +.No control\- Ns Ar X , +where +.Ar X +is any character. In particular, +.Ic ^^ +is +.Li control\-^. +.Ar Escape +is the escape key, or +.Ic ^\&[ . +.Bl -tag -width Ds +.It Ar # +Select window +.Ar # +as the current window +and return to conversation mode. +.It Ic \&% Ns Ar # +Select window +.Ar # +but stay in command mode. +.It Ic ^^ +Select the previous window and return to conversation +mode. This is useful for toggling between two windows. +.It Ic escape +Return to conversation mode. +.It Ic ^P +Return to conversation mode and write +.Ic ^P +to the +current window. Thus, typing two +.Ic ^P Ns 's +in conversation +mode sends one to the current window. If the +.Nm window +escape is changed to some other character, that +character takes the place of +.Ic ^P +here. +.It Ic ? +List a short summary of commands. +.It Ic ^L +Refresh the screen. +.It Ic q +Exit +.Nm window . +Confirmation is requested. +.It Ic ^Z +Suspend +.Nm window . +.It Ic w +Create a new window. The user is prompted for the positions +of the upper left and lower right corners of the window. +The cursor is placed on the screen and the keys ``h'', ``j'', +``k'', and ``l'' +move the cursor left, down, up, and right, respectively. +The keys ``H'', ``J'', ``K'', and ``L'' move the cursor to the respective +limits of the screen. Typing a number before the movement keys +repeats the movement that number of times. Return enters the cursor position +as the upper left corner of the window. The lower right corner +is entered in the same manner. During this process, +the placement of the new window is indicated by a rectangular +box drawn on the screen, corresponding to where the new window +will be framed. Typing escape at any point +cancels this command. +.Pp +This window becomes the current window, +and is given the first available ID. The default buffer size +is used (see +.Ar default_nline +command below). +.Pp +Only fully visible windows can be created this way. +.It Ic c Ns Ar # +Close window +.Ar # . +The process in the window is sent +the hangup signal (see +.Xr kill 1 ) . +.Xr Csh 1 +should +handle this signal correctly and cause no problems. +.It Ic m Ns Ar # +Move window +.Ar # +to another location. A box in the shape +of the window is drawn on +the screen to indicate the new position of the window, and the same keys as +those for the +.Ic w +command are used to position the box. The +window can be moved partially off-screen. +.It Ic M Ns Ar # +Move window +.Ar # +to its previous position. +.It Ic s Ns Ar # +Change the size of window +.Ar # . +The user is prompted +to enter the new lower right corner of the window. A box +is drawn to indicate the new window size. The same +keys used in +.Ic w +and +.Ic m +are used to enter the position. +.It Ic S Ns Ar # +Change window +.Ar # +to its previous size. +.It Ic ^Y +Scroll the current window up by one line. +.It Ic ^E +Scroll the current window down by one line. +.It Ic ^U +Scroll the current window up by half the window size. +.It Ic ^D +Scroll the current window down by half the window size. +.It Ic ^B +Scroll the current window up by the full window size. +.It Ic ^F +Scroll the current window down by the full window size. +.It Ic h +Move the cursor of the current window left by one column. +.It Ic j +Move the cursor of the current window down by one line. +.It Ic k +Move the cursor of the current window up by one line. +.It Ic l +Move the cursor of the current window right by one column. +.It Ic y +Yank. The user is prompted to enter two points within the current +window. Then the content of the current window between those two points +is saved in the yank buffer. +.It Ic p +Put. The content of the yank buffer is written to the current +window as input. +.It Ic ^S +Stop output in the current window. +.It Ic ^Q +Start output in the current window. +.It Ic : +Enter a line to be executed as long commands. +Normal line +editing characters (erase character, erase word, erase line) +are supported. +.El +.Ss Long Commands +Long commands are a sequence of statements +parsed much like a programming language, with a syntax +similar to that of C. Numeric and string expressions and variables +are supported, as well as conditional statements. +.Pp +There are two data types: string and number. A string is a sequence +of letters or digits beginning with a letter. ``_'' and ``.'' are +considered letters. Alternately, non-alphanumeric characters can +be included in strings by quoting them in ``"'' or escaping them +with ``\\''. In addition, the ``\\'' sequences of C are supported, +both inside and outside quotes (e.g., ``\\n'' is a new line, +``\\r'' a carriage return). For example, these are legal strings: +abcde01234, "&#$^*&#", ab"$#"cd, ab\\$\\#cd, "/usr/ucb/window". +.Pp +A number is an integer value in one of three forms: +a decimal number, an octal number preceded by ``0'', +or a hexadecimal number preceded by ``0x'' or ``0X''. The natural +machine integer size is used (i.e., the signed integer type +of the C compiler). As in C, a non-zero number represents +a boolean true. +.Pp +The character ``#'' begins a comment which terminates at the +end of the line. +.Pp +A statement is either a conditional or an expression. Expression +statements are terminated with a new line or ``;''. To continue +an expression on the next line, terminate the first line with ``\\''. +.Ss Conditional Statement +.Nm Window +has a single control structure: +the fully bracketed if statement in the form +.Pp +.Bd -literal -offset indent -compact +if then +\t +\t... +elsif then +\t +\t... +else +\t +\t... +endif +.Ed +.Pp +The +.Ic else +and +.Ic elsif +parts are optional, and the latter can +be repeated any number of times. + +must be numeric. +.Ss Expressions +Expressions in +.Nm window +are similar to those in the +C language, with most C operators supported on numeric +operands. In addition, some are overloaded to operate on strings. +.Pp +When an expression is used as a statement, its value is discarded +after evaluation. Therefore, only expressions with side +effects (assignments and function calls) are useful as statements. +.Pp +Single valued (no arrays) variables are supported, of both +numeric and string values. Some variables are predefined. They +are listed below. +.Pp +The operators in order of increasing precedence: +.Bl -tag -width Fl +.It Xo +.Aq Va expr1 +.Ic = +.Aq Va expr2 +.Xc +Assignment. The variable of name +.Aq Va expr1 , +which must be string valued, +is assigned the result of +.Aq Va expr2 . +Returns the value of +.Aq Va expr2 . +.It Xo +.Aq Va expr1 +.Ic ? +.Aq Va expr2 +.Ic : +.Aq Va expr3 +.Xc +Returns the value of +.Aq Va expr2 +if +.Aq Va expr1 +evaluates true +(non-zero numeric value); returns the value of +.Aq Va expr3 +otherwise. Only +one of +.Aq Va expr2 +and +.Aq Va expr3 +is evaluated. +.Aq Va Expr1 +must +be numeric. +.It Xo +.Aq Va expr1 +.Ic \&|\&| +.Aq Va expr2 +.Xc +Logical or. Numeric values only. Short circuit evaluation is supported +(i.e., if +.Aq Va expr1 +evaluates true, then +.Aq Va expr2 +is not evaluated). +.It Xo +.Aq Va expr1 +.Ic \&&\&& +.Aq Va expr2 +.Xc +Logical and with short circuit evaluation. Numeric values only. +.It Xo +.Aq Va expr1 +.Ic \&| +.Aq Va expr2 +.Xc +Bitwise or. Numeric values only. +.It Xo +.Aq Va expr1 +.Ic ^ +.Aq Va expr2 +.Xc +Bitwise exclusive or.

Numeric values only. +.It Xo +.Aq Va expr1 +.Ic == +.Aq Va expr2 , +.Aq Va expr1 +.Ic != +.Aq expr2 +.Xc +Comparison (equal and not equal, respectively). The boolean +result (either 1 or 0) of the comparison is returned. The +operands can be numeric or string valued. One string operand +forces the other to be converted to a string in necessary. +.It Xo +.Aq Va expr1 +.Ic < +.Aq Va expr2 , +.Aq Va expr1 +.Ic > +.Aq Va expr2 , +.Aq Va expr1 +.Ic <= +.Aq Va expr2 , +.Xc +Less than, greater than, less than or equal to, +greater than or equal to. Both numeric and string values, with +automatic conversion as above. +.It Xo +.Aq Va expr1 +.Ic << +.Aq Va expr2 , +.Aq Va expr1 +.Ic >> +.Aq Va expr2 +.Xc +If both operands are numbers, +.Aq Va expr1 +is bit +shifted left (or right) by +.Aq Va expr2 +bits. If +.Aq Va expr1 +is +a string, then its first (or last) +.Aq Va expr2 +characters are +returns (if +.Aq Va expr2 +is also a string, then its length is used +in place of its value). +.It Xo +.Aq Va expr1 +.Ic + +.Aq Va expr2 , +.Aq Va expr1 +.Ic - +.Aq Va expr2 +.Xc +Addition and subtraction on numbers. For ``+'', if one +argument is a string, then the other is converted to a string, +and the result is the concatenation of the two strings. +.It Xo +.Aq Va expr1 +.Ic \&* +.Aq Va expr2 , +.Aq Va expr1 +.Ic \&/ +.Aq Va expr2 , +.Aq Va expr1 +.Ic \&% +.Aq Va expr2 +.Xc +Multiplication, division, modulo. Numbers only. +.It Xo +.Ic \- Ns Aq Va expr , +.Ic ~ Ns Aq Va expr , +.Ic \&! Ns Aq Va expr , +.Ic \&$ Ns Aq Va expr , +.Ic \&$? Ns Aq Va expr +.Xc +The first three are unary minus, bitwise complement and logical complement +on numbers only. The operator, ``$'', takes +.Aq Va expr +and returns +the value of the variable of that name. If +.Aq Va expr +is numeric +with value +.Ar n +and it appears within an alias macro (see below), +then it refers to the nth argument of the alias invocation. ``$?'' +tests for the existence of the variable +.Aq Va expr , +and returns 1 +if it exists or 0 otherwise. +.It Xo +.Ao Va expr Ac Ns Pq Aq Ar arglist +.Xc +Function call. +.Aq Va Expr +must be a string that is the unique +prefix of the name of a builtin +.Nm window +function +or the full name of a user defined alias macro. In the case of a builtin +function, +.Aq Ar arglist +can be in one of two forms: +.Bd -literal -offset indent +, , ... +argname1 = , argname2 = , ... +.Ed +.Pp +The two forms can in fact be intermixed, but the result is +unpredictable. Most arguments can be omitted; default values will +be supplied for them. The +.Ar argnames +can be unique prefixes +of the argument names. The commas separating +arguments are used only to disambiguate, and can usually be omitted. +.Pp +Only the first argument form is valid for user defined aliases. Aliases +are defined using the +.Ic alias +builtin function (see below). Arguments +are accessed via a variant of the variable mechanism (see ``$'' operator +above). +.Pp +Most functions return value, but some are used for side effect +only and so must be used as statements. When a function or an alias is used +as a statement, the parentheses surrounding +the argument list may be omitted. Aliases return no value. +.El +.Ss Builtin Functions +The arguments are listed by name in their natural +order. Optional arguments are in square brackets +.Sq Op . +Arguments +that have no names are in angle brackets +.Sq <> . +An argument meant to be a boolean flag (often named +.Ar flag ) +can be one of +.Ar on , +.Ar off , +.Ar yes , +.Ar no , +.Ar true , +or +.Ar false , +with +obvious meanings, or it can be a numeric expression, +in which case a non-zero value is true. +.Bl -tag -width Fl +.It Xo +.Ic alias Ns Po Bq Aq Ar string , +.Bq Aq Ar string\-list Pc +.Xc +If no argument is given, all currently defined alias macros are +listed.

Initially, +the default shell is taken from the environment variable +.Ev SHELL . +.It Ic default_smooth Ns Pq Bq Ar flag +Set the default value of the +.Ar smooth +argument +to the command +.Nm window +(see below). The argument +is a boolean flag (one of +.Ar on , +.Ar off , +.Ar yes , +.Ar no , +.Ar true , +.Ar false , +or a number, +as described above). Default is no change. +The old value (as a number) is returned. +The initial value is 1 (true). +.It Xo +.Ic echo Ns ( Op Ar window , +.Bq Aq Ar string\-list ) +.Xc +Write the list of strings, +.Aq Ar string-list , +to +.Nm window , +separated +by spaces and terminated with a new line.

Otherwise, +the default buffer size is used. Default values for +.Ar row , +.Ar column , +.Ar nrow , +and +.Ar ncol +are, respectively, +the upper, left-most, lower, or right-most extremes of the +screen. +.Ar Label +is the label string. +.Ar Frame , +.Ar pty , +and +.Ar mapnl +are flag values +interpreted in the same way as the argument to +.Ar foreground +(see above); +they mean, respectively, put a frame around this window (default true), +allocate pseudo-terminal for this window rather than socketpair (default +true), and map new line characters in this window to carriage return +and line feed (default true if socketpair is used, false otherwise). +Normally, a window is automatically closed when its process +exits. Setting +.Ar keepopen +to true (default false) prevents this +action. When +.Ar smooth +is true, the screen is updated more frequently +(for this window) to produce a more terminal-like behavior. +The default value of +.Ar smooth +is set by the +.Ar default_smooth +command (see above). +.Ar Shell +is a list of strings that will be used as the shell +program to place in the window (default is the program specified +by +.Ar default_shell , +see above).
