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 Any files +that are out of date will be displayed but no files will be changed +nor any mail sent.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 +<variable name> `=' <name list> +[label:]<source list> `\->' <destination list> <command list> +[label:]<source list> `::' <time_stamp file> <command list> +.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 +<name> +.Ed +or +.Bd -literal -offset indent -compact +`(' <zero or more names separated by white-space> `)' +.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' <options> opt_dest_name `;' +.It `notify' <name list> `;' +.It `except' <name list> `;' +.It `except_pat' <pattern list> `;' +.It `special' <name list> 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. A means of updating file modes and owners +of otherwise identical files is also needed. |
