This directory (whis was supposed to do indexes etc for the printable

documentation) hasn't had its nappies changed since FreeBSD-2.0, and
is now starting to smell rather ripe.

Its dependant on ancient and removed tools, and the last maintainer
can't remember looking at it 1 1/2 years ago.

If we need it, its in the Attic.

-These files have been somewhat updated so that they at least format
-without fatal errors under FreeBSD 2.0-current (and so presumably 2.1).
-Some parts are not very accurate, and quite a bit of extra verbiage
-should probably be added describing FreeBSD additions relative to 4.4.
-The formatting is not perfect, and groff generates copious errors which
-hopefully some [nt]roff expert will actually look into some day.  The entire
-suite needs to be fixed to learn to live with obj directories, in line
-with our goal to have a completely read-only source tree, before it can
-be added to the top-level Makefile (if it is even then).
-
-The man[1-8] files were generated through the following process:
-	locate *.1
-	pipe through a long series of fgrep and sed commands to fix up
-	sort-regexp ^.*/\([^/]*\)$ \1 in Emacs
-	visually inspect the result for duplicates and false matches
-

-Currently these files are in the prospect of being updated to work on newer
-FreeBSD releases again.

-.NH 1
-Introduction
-.PP
-The major new facilities available in the 4.4BSD release are
-a new virtual memory system, 
-the addition of ISO/OSI networking support,
-a new virtual filesystem interface supporting filesystem stacking,
-a freely redistributable implementation of NFS,
-a log-structured filesystem,
-enhancement of the local filesystems to support
-files and filesystems that are up to 2^63 bytes in size,
-enhanced security and system management support,
-and the conversion to and addition of the IEEE Std1003.1 (``POSIX'')
-facilities and many of the IEEE Std1003.2 facilities.
-In addition, many new utilities and additions have been made to the C-library.
-The kernel sources have been reorganized to collect all machine-dependent
-files for each architecture under one directory,
-and most of the machine-independent code is now free of code
-conditional on specific machines.
-The user structure and process structure have been reorganized
-to eliminate the statically-mapped user structure and to make most
-of the process resources shareable by multiple processes.
-The system and include files have been converted to be compatible
-with ANSI C, including function prototypes for most of the exported
-functions.
-There are numerous other changes throughout the system.
-.NH 1
-Changes in the Kernel
-.PP
-This release includes several important structural kernel changes.
-The kernel uses a new internal system call convention;
-the use of global (``u-dot'') variables for parameters and error returns
-has been eliminated,
-and interrupted system calls no longer abort using non-local goto's (longjmp's).
-A new sleep interface separates signal handling from scheduling priority,
-returning characteristic errors to abort or restart the current system call.
-This sleep call also passes a string describing the process state,
-which is used by the ps(1) program.
-The old sleep interface can be used only for non-interruptible sleeps.
-.PP
-Many data structures that were previously statically allocated
-are now allocated dynamically.
-These structures include mount entries, file entries,
-user open file descriptors, the process entries, the vnode table,
-the name cache, and the quota structures.
-.PP
-The 4.4BSD distribution adds support for several new architectures including
-SPARC-based Sparcstations 1 and 2,
-MIPS-based Decstation 3100 and 5000 and Sony NEWS,
-68000-based Hewlett-Packard 9000/300 and Omron Luna, and
-386-based Personal Computers.
-Both the HP300 and SPARC ports feature the ability to run binaries
-built for the native operating system (HP-UX or SunOS) by emulating
-their system calls.
-Though this native operating system compatibility was provided by the
-developers as needed for their purposes and is by no means complete,
-it is complete enough to run several non-trivial applications including
-those that require HP-UX or SunOS shared libraries.
-For example, the vendor supplied X11 server and windowing environment
-can be used on both the HP300 and SPARC.
-.NH 2
-Virtual memory changes
-.PP
-The new virtual memory implementation is derived from the MACH
-operating system developed at Carnegie-Mellon,
-and was ported to the BSD kernel at the University of Utah.
-The MACH virtual memory system call interface has been replaced with the
-``mmap''-based interface described in the ``Berkeley Software
-Architecture Manual''.
-The interface is similar to the interfaces shipped
-by several commercial vendors such as Sun, USL, and Convex Computer Corp.
-The integration of the new virtual memory is functionally complete,
-but, like most MACH-based virtual memory systems,
-still has serious performance problems under heavy memory load.
-.NH 2
-Networking additions and changes
-.PP
-The ISO/OSI Networking consists of a kernel implementation of
-transport class 4 (TP-4),
-connectionless networking protocol (CLNP),
-and 802.3-based link-level support (hardware-compatible with Ethernet*).
-.FS
-*Ethernet is a trademark of the Xerox Corporation.
-.FE
-We also include support for ISO Connection-Oriented Network Service,
-X.25, TP-0.
-The session and presentation layers are provided outside
-the kernel by the ISO development environment (ISODE).
-Included in this development environment are file
-transfer and management (FTAM), virtual terminals (VT),
-a directory services implementation (X.500), and miscellaneous other utilities.
-.PP
-Several important enhancements have been added to the TCP/IP
-protocols including TCP header prediction and
-serial line IP (SLIP) with header compression.
-The routing implementation has been completely rewritten
-to use a hierarchical routing tree with a mask per route
-to support the arbitrary levels of routing found in the ISO protocols.
-The routing table also stores and caches route characteristics
-to speed the adaptation of the throughput and congestion avoidance
-algorithms.
-.NH 2
-Additions and changes to filesystems
-.PP
-The 4.4BSD distribution contains most of the interfaces
-specified in the IEEE Std1003.1 system interface standard.
-Filesystem additions include IEEE Std1003.1 FIFOs,
-byte-range file locking, and saved user and group identifiers.
-.PP
-A new virtual filesystem interface has been added to the
-kernel to support multiple filesystems.
-In comparison with other interfaces,
-the Berkeley interface has been structured for more efficient support
-of filesystems that maintain state (such as the local filesystem).
-The interface has been extended with support for stackable
-filesystems done at UCLA.
-These extensions allow for filesystems to be layered on top of each
-other and allow new vnode operations to be added without requiring
-changes to existing filesystem implementations.
-For example, the umap filesystem
-is used to mount a sub-tree of an existing filesystem
-that uses a different set of uids and gids than the local system.
-Such a filesystem could be mounted from a remote site via NFS or it
-could be a filesystem on removable media brought from some foreign
-location that uses a different password file.
-.PP
-In addition to the local ``fast filesystem'',
-we have added an implementation of the network filesystem (NFS)
-that fully interoperates with the NFS shipped by Sun and its licensees.
-Because our NFS implementation was implemented using only the
-publicly available NFS specification,
-it does not require a license from Sun to use in source or binary form.
-By default it runs over UDP to be compatible with Sun's implementation.
-However, it can be configured on a per-mount basis to run over TCP.
-Using TCP allows it to be used quickly and efficiently through
-gateways and over long-haul networks.
-Using an extended protocol, it supports Leases to allow a limited
-callback mechanism that greatly reduces the network traffic necessary
-to maintain cache consistency between the server and its clients.
-.PP
-A new log-structured filesystem has been added that provides
-near disk-speed output and fast crash recovery.
-It is still experimental in the 4.4BSD release,
-so we do not recommend it for production use.
-We have also added a memory-based filesystem that runs in
-pageable memory, allowing large temporary filesystems without
-requiring dedicated physical memory.
-.PP
-The local ``fast filesystem'' has been enhanced to do 
-clustering which allows large pieces of files to be
-allocated contiguously resulting in near doubling
-of filesystem throughput.
-The filesystem interface has been extended to allow
-files and filesystems to grow to 2^63 bytes in size.
-The quota system has been rewritten to support both
-user and group quotas (simultaneously if desired).
-Quota expiration is based on time rather than
-the previous metric of number of logins over quota.
-This change makes quotas more useful on fileservers
-onto which users seldom login.
-.PP
-The system security has been greatly enhanced by the
-addition of additional file flags that permit a file to be
-marked as immutable or append only.
-Once set, these flags can only be cleared by the super-user
-when the system is running single user.
-To protect against indiscriminate reading or writing of kernel
-memory, all writing and most reading of kernel data structures
-must be done using a new ``sysctl'' interface.
-The information to be access is described through an extensible
-``Management Information Base'' (MIB).
-.NH 2
-POSIX terminal driver changes
-.PP
-The biggest area of change is a new terminal driver.
-The terminal driver is similar to the System V terminal driver
-with the addition of the necessary extensions to get the
-functionality previously available in the 4.3BSD terminal driver.
-4.4BSD also adds the IEEE Std1003.1 job control interface,
-which is similar to the 4.3BSD job control interface,
-but adds a security model that was missing in the
-4.3BSD job control implementation.
-A new system call, \fIsetsid\fP,
-creates a job-control session consisting of a single process
-group with one member, the caller, that becomes a session leader.
-Only a session leader may acquire a controlling terminal.
-This is done explicitly via a \s-1TIOCSCTTY\s+1 \fIioctl\fP call,
-not implicitly by an \fIopen\fP call.
-The call fails if the terminal is in use.
-.PP
-For backward compatibility,
-both the old \fIioctl\fP
-calls and old options to \fIstty\fP
-are emulated.
-.NH 1
-Changes to the utilities
-.PP
-There are several new tools and utilities included in this release.
-A new version of ``make'' allows much-simplified makefiles for the
-system software and allows compilation for multiple architectures
-from the same source tree (which may be mounted read-only).
-Notable additions to the libraries include functions to traverse a
-filesystem hierarchy, database interfaces to btree and hashing functions,
-a new, fast implementation of stdio and a radix sort function.
-The additions to the utility suite include greatly enhanced versions of
-programs that display system status information, implementations of
-various traditional tools described in the IEEE Std1003.2 standard,
-and many others.
-.PP
-We have been tracking the IEEE Std1003.2 shell and utility work
-and have included prototypes of many of the proposed utilities.
-Most of the traditional utilities have been replaced
-with implementations conformant to the POSIX standards.
-Almost the entire manual suite has been rewritten to
-reflect the POSIX defined interfaces.
-In rewriting this software, we have generally
-been rewarded with significant performance improvements.
-Most of the libraries and header files have been converted
-to be compliant with ANSI C.
-The system libraries and utilities all compile
-with either ANSI or traditional C.
-.PP
-The Kerberos (version 4) authentication software has been
-integrated into much of the system (including NFS) to provide
-the first real network authentication on BSD.
-.PP
-A new implementation of the \fIex/vi\fP text editors is available
-in this release.
-It is intended as a bug-for-bug compatible version of the editors.
-It also has a few new features: 8-bit clean data, lines and files
-limited only by memory and disk space, split screens, tags stacks
-and left-right scrolling among them.
-\fINex/nvi\fP
-is not yet production quality; future versions of this software may
-be retrieved by anonymous ftp from ftp.cs.berkeley.edu, in the
-directory ucb/4bsd.
-.PP
-The \fIfind\fP
-utility has two new options that are important to be aware of if you
-intend to use NFS.
-The ``fstype'' and ``prune'' options can be used together to prevent
-find from crossing NFS mount points.
-.NH 2
-Additions and changes to the libraries
-.PP
-The \fIcurses\fP
-library has been largely rewritten.
-Important additional features include support
-for scrolling and \fItermios\fP.
-.PP
-An application front-end editing library, named libedit, has been
-added to the system.
-.PP
-A superset implementation of the SunOS kernel memory interface library,
-\fIlibkvm\fP, has been integrated into the system.
-.PP
-Nearly the entire C-library has been rewritten.
-Some highlights of the changes to the 4.4BSD C-library:
-.IP \(bu
-The newly added \fIfts\fP
-functions will do either physical or logical traversal of
-a file hierarchy as well as handle essentially infinite depth
-filesystems and filesystems with cycles.
-All the utilities in 4.4BSD that traverse file hierarchies
-have been converted to use \fIfts\fP.
-The conversion has always resulted in a significant performance
-gain, often of four or five to one in system time.
-.IP \(bu
-The newly added \fIdbopen\fP
-functions are intended to be a family of database access methods.
-Currently, they consist of \fIhash\fP,
-an extensible, dynamic hashing scheme,
-\fIbtree\fP, a sorted, balanced tree structure (B+tree's), and
-\fIrecno\fP, a flat-file interface for fixed or variable length records
-referenced by logical record number.
-Each of the access methods stores associated key/data pairs and
-uses the same record oriented interface for access.
-Future versions of this software may be retrieved by anonymous ftp
-from ftp.cs.berkeley.edu, in the directory ucb/4bsd.
-.IP \(bu
-The \fIqsort\fP
-function has been rewritten for additional performance.
-In addition, three new types of sorting functions,
-\fIheapsort\fP, \fImergesort\fP, and \fIradixsort\fP
-have been added to the system.
-The \fImergesort\fP
-function is optimized for data with pre-existing order,
-in which case it usually significantly outperforms \fIqsort\fP.
-The \fIradixsort\fP
-functions are variants of most-significant-byte radix sorting.
-They take time linear to the number of bytes to be
-sorted, usually significantly outperforming \fIqsort\fP
-on data that can be sorted in this fashion.
-An implementation of the POSIX 1003.2 standard \fIsort\fP
-based on \fIradixsort\fP is included in 4.4BSD.
-.IP \(bu
-The floating point support in the C-library has been replaced
-and is now accurate.
-.IP \(bu
-The C functions specified by both ANSI C, POSIX 1003.1 and
-1003.2 are now part of the C-library.
-This includes support for file name matching, shell globbing
-and both basic and extended regular expressions.
-.IP \(bu
-ANSI C multibyte and wide character support has been integrated.
-The rune functionality from the Bell Labs' Plan 9 system is provided
-as well.
-.IP \(bu
-The \fItermcap\fP
-functions have been generalized and replaced with a general
-purpose interface named \fIgetcap\fP.
-.IP \(bu
-The \fIstdio\fP
-routines have been replaced, and are usually much faster.
-In addition, the \fIfunopen\fP
-interface permits applications to provide their own I/O stream
-function support.

-This manual reflects the Berkeley system mid-October, 1980.
-A large amount of tuning has been done in the system since the last release;
-we hope this provides as noticeable an improvement for you as it did for us.
-This release finds the system in transition; a number of facilities
-have been added in experimental versions (job control, resource limits)
-and the implementation of others is imminent (shared-segments, higher
-performance from the filesystem, etc.).
-Applications which use facilities that are in transition should be aware
-that some of the system calls and library routines will change
-in the near future.  We have tried to be conscientious and make it
-very clear where this is likely.

-Documents''.
-References to manual pages are given as ``\fIname\fP(section)'' thus
-.IR sh (1)
-refers to the shell manual entry in section 1.
-.LP
-The manual pages give descriptions of the features of the
-4.4BSD system, as developed at the University of California at Berkeley.
-They do not attempt to provide perspective or tutorial information about the
-4.4BSD operating system, its facilities, or its implementation.
-Various documents on those topics are contained in the

-.LP
-Within the area it surveys, this volume attempts to be timely, complete
-and concise.  Where the latter two objectives conflict,
-the obvious is often left unsaid in favor of brevity.
-It is intended that each program be described as it is, not as it should be.
-Inevitably, this means that various sections will soon be out of date.
-.LP
-Commands are programs intended to be invoked directly by
-the user, in contrast to subroutines, that are
-intended to be called by the user's programs.
-User commands are described in URM section 1.
-Commands generally reside in directory
-.I /bin
-(for
-.IR bin \|ary
-programs).
-Some programs also reside in
-.I
-/\|usr/\|bin,
-.R
-to save space in
-.I  /\|bin.
-.R
-These directories are searched automatically by the command interpreters.
-Additional directories that may be of interest include
-.I
-/\|usr/\|contrib/\|bin,
-.R
-which has contributed software
-.I
-/\|usr/\|old/\|bin,
-.R
-which has old but sometimes still useful software and
-.I
-/\|usr/\|local/\|bin,
-.R
-which contains software local to your site.
-.LP
-Games have been relegated to URM section 6 and
-.I
-/\|usr/\|games,
-.R
-to keep them from contaminating
-the more staid information of URM section 1.
-.LP
-Miscellaneous collection of information necessary for
-writing in various specialized languages such as character codes, 
-macro packages for typesetting, etc is contained in URM section 7.
-.LP
-System calls are entries into the BSD kernel.
-The system call interface is identical to a C language
-procedure call; the equivalent C procedures are described in PRM section 2.
-.LP
-An assortment of subroutines is available;
-they are described in PRM section 3.
-The primary libraries in which they are kept are described in
-.IR intro (3).
-The functions are described in terms of C.
-.LP
-PRM section 4 discusses the characteristics of
-each system ``file'' that refers to an I/O device.
-The names in this section refer to the HP300 device names for the hardware,
-instead of the names of the special files themselves.
-.LP
-The file formats and conventions (PRM section 5)
-documents the structure of particular kinds of files;
-for example, the form of the output of the loader and
-assembler is given.  Excluded are files used by only one command,
-for example the assembler's intermediate files.
-.LP
-Commands and procedures intended for use primarily by the
-system administrator are described in SMM section 8.
-The files described here are almost all kept in the directory
-.I /\|etc.
-The system administration binaries reside in
-.I
-/\|sbin,
-.R
-and
-.I
-/\|usr/\|sbin.
-.LP
-Each section consists of independent entries of a page or so each.
-The name of the entry is in the upper corners of its pages,
-together with the section number.
-Entries within each section are alphabetized.
-The page numbers of each entry start at 1;
-it is infeasible to number consecutively the pages of 
-a document like this that is republished in many variant forms.
-.LP
-All entries are based on a common format;
-not all subsections always appear.
-.RS
-.LP
-The
-.I name
-subsection lists the exact names of the commands and subroutines
-covered under the entry and gives a short description of their purpose.
-.LP
-The
-.IR synopsis ""
-summarizes the use of the program being described.
-A few conventions are used, particularly in the Commands subsection:
-.LP
-.RS
-.B Boldface
-words are considered literals, and are typed just as they appear.
-.LP
-Square brackets [ ] around an argument show that the argument is optional.
-When an argument is given as ``name'', it always refers to a file name.
-.LP
-Ellipses ``.\|.\|.'' are used to show that the previous argument-prototype
-may be repeated.
-.LP
-A final convention is used by the commands themselves.
-An argument beginning with a minus sign ``\-'' usually means that it is an
-option-specifying argument, even if it appears in a position where
-a file name could appear.  Therefore, it is unwise to have files whose
-names begin with ``\-''.
-.LP
-.RE
-The
-.IR description ""
-subsection discusses in detail the subject at hand.
-.LP
-The

-.RE
-At the beginning of URM is a table of contents,
-organized by section and alphabetically within each section.
-There is also a permuted index derived from the table of contents.
-Within each index entry, the title of the writeup to which
-it refers is followed by the appropriate section number in parentheses.
-This fact is important because there is considerable
-name duplication among the sections, arising principally from commands that
-exist only to exercise a particular system call.
-Finally, there is a list of documents on the inside back cover of each volume.
-.SH
-HOW TO GET STARTED
-.LP
-This section sketches the basic information you need to get started on \s-1UNIX\s+1;
-how to log in and log out, how to communicate through your terminal,
-and how to run a program.
-See ``\s-1UNIX\s+1 for Beginners'' in (USD:1) for a
-more complete introduction to the system.
-.LP
-.I
-Logging in.\ \ 
-.R
-Almost any ASCII terminal capable of
-full duplex operation and generating
-the entire character set can be used.
-You must have a valid user name,
-which may be obtained from the system administration.
-If you will be accessing \s-1UNIX\s+1 remotely, you will also
-need to obtain the telephone number for the system that you will be using.
-.LP
-After a data connection is established,
-the login procedure depends on what type of terminal you are using
-and local system conventions.
-If your terminal is directly connected to the computer,
-it generally runs at 9600 or 19200 baud.
-If you are using a modem running over a phone line,
-the terminal must be set at the speed appropriate for the modem you are using,
-typically 1200, 2400, or 9600 baud.
-The half/full duplex switch should always be set at full-duplex.
-(This switch will often have to be changed
-since many other systems require half-duplex).
-.LP
-When a connection is established, the system types ``login:'';
-you type your user name, followed by the ``return'' key.
-If you have a password, the system asks for it
-and suppresses echo to the terminal so the password will not appear.
-After you have logged in, the ``return'', ``new line'', or ``linefeed'' keys
-will give exactly the same results.
-A message-of-the-day usually greets you before your first prompt.
-.LP
-If the system types out a few garbage characters
-after you have established a data connection
-(the ``login:'' message at the wrong speed),
-depress the ``break'' (or ``interrupt'') key.
-This is a speed-independent signal to \s-1UNIX\s+1
-that a different speed terminal is in use.
-The system then will type ``login:,'' this time at another speed.
-Continue depressing the break key until ``login:'' appears clearly,
-then respond with your user name.
-.LP
-For all these terminals, it is important
-that you type your name in lower-case if possible; if you type
-upper-case letters,
-\s-1UNIX\s+1 will assume that your terminal cannot generate lower-case
-letters and will translate all subsequent lower-case letters to upper case.
-.LP
-The evidence that you have successfully logged in is that a shell program
-will type a prompt (``$'' or ``%'') to you.
-(The shells are described below under ``How to run a program.'')
-.LP
-For more information, consult
-.IR tset (1),
-and
-.IR stty (1),
-which tell how to adjust terminal behavior;
-.IR getty (8)
-discusses the login sequence in more detail, and
-.IR tty (4)
-discusses terminal I/O.
-.LP
-.I
-Logging out.\ \ 
-.R
-There are three ways to log out:
-.IP
-By typing ``logout'' or an end-of-file
-indication (EOT character, control-D) to the shell.
-The shell will terminate and the ``login:'' message will appear again.
-.IP
-You can log in directly as another user by giving a
-.IR login (1)
-command.
-.IP
-If worse comes to worse,
-you can simply hang up the phone; but beware \- some machines may
-lack the necessary hardware to detect that the phone has been hung up.
-Ask your system administrator if this is a problem on your machine.
-.LP
-.I
-How to communicate through your terminal.\ \ 
-.R
-When you type characters, a gnome deep in the system
-gathers your characters and saves them in a secret place.
-The characters will not be given to a program
-until you type a return (or newline), as described above in
-.I
-Logging in.
-.R
-.LP
-\s-1UNIX\s+1 terminal I/O is full-duplex.
-It has full read-ahead, which means that you can type at any time,
-even while a program is typing at you.
-Of course, if you type during output, the printed output will
-have the input characters interspersed.
-However, whatever you type will be saved up and interpreted in correct sequence.
-There is a limit to the amount of read-ahead,
-but it is generous and not likely to be exceeded unless
-the system is in trouble.
-When the read-ahead limit is exceeded, the system
-throws away all the saved characters (or beeps, if your prompt was a ``%'').
-.LP
-The ^U (control-U) character in typed input kills all the
-preceding characters in the line,
-so typing mistakes can be repaired on a single line.
-Also, the delete character (DEL) or sometimes the
-backspace character (control-H) erases the last character typed.
-.IR Tset (1)
-or
-.IR stty (1)
-can be used to change these defaults.
-Successive uses of delete (or backspace) erases characters back to, but
-not beyond, the beginning of the line.
-DEL and ^U (control-U) can be transmitted to a program by preceding them with
-^V (control-V).
-(So, to erase ^V (control-V), you need two deletes or backspaces).
-.LP
-An
-.I
-interrupt signal
-.R
-is sent to a program by typing ^C (control-C) or the ``break'' key
-which is not passed to programs.
-This signal generally causes whatever program you are running to terminate.
-It is typically used to stop a long printout that you do not want.
-However, programs can arrange either to ignore this signal altogether,
-or to be notified when it happens (instead of being terminated).
-The editor, for example, catches interrupts and stops what it is doing,
-instead of terminating, so that an interrupt can
-be used to halt an editor printout without losing the file being edited.
-The interrupt character can also be changed with
-.IR tset (1)
-or
-.IR stty (1).
-.LP
-It is also possible to suspend output temporarily using ^S (control-S)
-and later resume output with ^Q (control-Q).
-Output can be thrown away without interrupting
-the program by typing ^O (control-O); see
-.IR tty (4).
-.LP
-The
-.IR quit ""
-signal is generated by typing the \s8ASCII\s10 FS character.
-(FS appears many places on different terminals, most commonly
-as control-\e or control-\^|\^.)
-It not only causes a running program to terminate
-but also generates a file with the core image of the terminated process.
-Quit is useful for debugging.
-.LP
-Besides adapting to the speed of the terminal,
-\s-1UNIX\s+1 tries to be intelligent about whether
-you have a terminal with the newline function
-or whether it must be simulated with carriage-return and line-feed.
-In the latter case, all input carriage returns
-are turned to newline characters (the standard line delimiter)
-and both a carriage return and a line feed are echoed to the terminal.
-If you get into the wrong mode, the
-.IR reset (1)
-command will rescue you.
-If the terminal does not appear to be echoing anything that you type,
-it may be stuck in ``no-echo'' or ``raw'' mode.
-Try typing ``(control-J)reset(control-J)'' to recover.
-.LP
-Tab characters are used freely in \s-1UNIX\s+1 source programs.
-If your terminal does not have the tab function,
-you can arrange to have them turned into spaces
-during output, and echoed as spaces during input.
-The system assumes that tabs are set every eight columns.
-Again, the
-.IR tset (1)
-or
-.IR stty (1)
-command can be used to change these defaults.
-.IR Tset (1)
-can be used to set the tab stops automatically when necessary.
-.LP
-.I
-How to run a program; the shells.\ \ 
-.R
-When you have successfully logged in, a program
-called a shell is listening to your terminal.
-The shell reads typed-in lines, splits them up
-into a command name and arguments, and executes the command.
-A command is simply an executable program.
-The shell looks in several system directories to find the command.
-You can also place commands in your own directory and
-have the shell find them there.
-There is nothing special about system-provided
-commands except that they are kept in a directory where the shell can find them.
-.LP
-The command name is always the first word on an input line;
-it and its arguments are separated from one another by spaces.
-.LP
-When a program terminates, the shell will ordinarily regain control and type 
-a prompt at you to show that it is ready for another command.
-.LP
-The shells have many other capabilities, that are described in detail in
-sections
-.IR sh (1)
-and
-.IR csh (1).
-If the shell prompts you with ``$'', then it is an instance of
-.IR sh (1),
-the original \s-1UNIX\s+1 shell.
-If it prompts with ``%'' then it is an instance of
-.IR csh (1),
-a shell written at Berkeley.
-The shells are different for all but the most simple terminal usage.
-Most users at Berkeley choose
-.IR csh (1)
-because of the
-.I history
-mechanism and the
-.I alias
-feature, that greatly enhance its power when used interactively.
-.I Csh
-also supports the job-control facilities;
-see
-.IR csh (1)
-or the Csh introduction in USD:4 for details.
-.LP
-You can change from one shell to the other by using the
-.I chpass (1)
-command, which takes effect at your next login.
-.LP
-.I
-The current directory.\ \ 
-.R
-\s-1UNIX\s+1 has a filesystem arranged as a hierarchy of directories.
-When the system administrator gave you a user name,
-they also created a directory for you (ordinarily
-with the same name as your user name).
-When you log in, any file name you type is by default in this directory.
-Since you are the owner of this directory, you have
-full permission to read, write, alter, or destroy its contents.
-Permissions to have your will with other directories
-and files will have been granted or denied to you by their owners.
-As a matter of observed fact, few \s-1UNIX\s+1
-users protect their files from perusal by other users.
-.LP
-To change the current directory (but not the set of permissions you
-were endowed with at login) use
-.IR cd (1).
-.LP
-.I
-Path names.\ \ 
-.R
-To refer to files not in the current directory, you must use a path name.
-Full path names begin with ``/\|'', the name of the root directory of the
-whole filesystem.
-After the slash comes the name of each directory containing the next
-sub-directory (followed by a ``/\|'') until finally the file name is reached.
-For example,
-.I
-/\^var/\^tmp/\^filex
-.R
-refers to the file
-.I
-filex
-.R
-in the directory
-.I
-tmp; tmp
-.R
-is itself a subdirectory of
-.I
-var; var
-.R
-springs directly from the root directory.
-.LP
-If your current directory has subdirectories,
-the path names of files therein begin with
-the name of the subdirectory with no prefixed ``/\|''.
-.LP
-A path name may be used anywhere a file name is required.
-.LP
-Important commands that modify the contents of files are
-.IR cp (1),
-.IR mv (1),
-and
-.IR rm (1),
-which respectively copy, move (i.e. rename) and remove files.
-To find out the status of files or directories, use 
-.IR ls (1).
-See
-.IR mkdir (1)
-for making directories and
-.IR rmdir (1)
-for destroying them.
-.LP
-For a fuller discussion of the filesystem, see
-``A Fast File System for \s-1UNIX\s+1'' (SMM:5)
-by McKusick, Joy, Leffler, and Fabry.
-It may also be useful to glance through PRM section 2,
-that discusses system calls, even if you do not intend
-to deal with the system at that level.
-.LP
-.I
-Writing a program.\ \ 
-.R
-To enter the text of a source program into a \s-1UNIX\s+1 file,
-use the standard display editor
-.IR vi (1)
-or its \s-1WYSIWYG\s+1 counterparts
-.IR jove (1)
-and
-.IR emacs (1).
-(The old standard editor
-.IR ed (1)
-is also available.)
-The principle language in \s-1UNIX\s+1 is provided by the C compiler
-.IR cc (1).
-User contributed software in the latest
-release of the system supports the programming languages perl and C++.
-After the program text has been entered through the editor
-and written to a file, you can give the file
-to the appropriate language processor as an argument.
-The output of the language processor
-will be left on a file in the current directory named ``a.out''.
-If the output is precious, use
-.IR mv (1)
-to move it to a less exposed name after successful compilation.
-.LP
-When you have finally gone through this entire process
-without provoking any diagnostics, the resulting program
-can be run by giving its name to the shell
-in response to the shell (``$'' or ``%'') prompt.
-.LP
-Your programs can receive arguments from the command line
-just as system programs do,
-see ``\s-1UNIX\s+1 Programming - Second Edition'' (PSD:4),
-or for a more terse description
-.IR execve (2).
-.LP
-.I
-Text processing.\ \ 
-.R
-Almost all text is entered through an editor such as
-.IR vi (1),
-.IR jove (1),
-or
-.IR emacs (1).
-The commands most often used to write text on a terminal are:
-.IR cat (1),
-.IR more (1),
-and
-.IR nroff (1).
-.LP
-The
-.IR cat (1)
-command simply dumps \s8ASCII\s10 text
-on the terminal, with no processing at all.
-.IR More (1)
-is useful for preventing the output of a command from
-scrolling off the top of your screen.
-It is also well suited to perusing files.
-.IR Nroff (1)
-is an elaborate text formatting program.
-Used naked, it requires careful forethought, but for
-ordinary documents it has been tamed; see
-.IR me (7)
-and
-.IR ms (7).
-.LP
-.IR Groff (1)
-converts documents to postscript for output to a
-Laserwriter or Phototypesetter.
-It is similar to 
-.IR nroff (1),
-and often works from exactly the same source text.
-It was used to produce this manual.
-.LP
-.IR Script (1)
-lets you keep a record of your session in a file,
-which can then be printed, mailed, etc.
-It provides the advantages of a hard-copy terminal
-even when using a display terminal.
-.LP
-.I
-Status inquiries.\ \ 
-.R
-Various commands exist to provide you with useful information.
-.IR w (1)
-prints a list of users currently logged in, and what they are doing.
-.IR date (1)
-prints the current time and date.
-.IR ls (1)
-will list the files in your directory or give
-summary information about particular files.
-.LP
-.I
-Surprises.\ \ 
-.R
-Certain commands provide inter-user communication.
-Even if you do not plan to use them, it would be
-well to learn something about them, because someone else may aim them at you.
-.LP
-To communicate with another user currently logged in,
-.IR write (1)
-or
-.IR talk (1)
-is used;
-.IR mail (1)
-will leave a message whose presence will be announced
-to another user when they next log in.
-The write-ups in the manual also suggest how to respond to
-the these commands if you are a target.
-.LP
-If you use
-.IR csh (1)
-the key ^Z (control-Z) will cause jobs to ``stop''.
-If this happens before you learn about it,
-you can simply continue by saying ``fg'' (for foreground) to bring
-the job back.
-.LP
-We hope that you will come to enjoy using the BSD system.
-Although it is very large and contains many commands,
-you can become very productive using only a small subset of them.
-As your needs expand to doing new tasks,
-you will almost always find that the system has the facilities
-that you need to accomplish them easily and quickly.
-.LP
-Most importantly, the source code to the BSD system
-is cheaply available to anyone that wants it.
-On many BSD systems, it can be found in the directory
-.IR /\|usr/\|src .
-You may simply want to find out how something works
-or fix some important bug without waiting months for
-your vendor to respond.
-It is also particularly useful if you
-want to grab another piece of code to bootstrap a new project.
-Provided that you retain the copyrights and acknowledgements
-at the top of each file, you are free to redistribute your
-work for fun or profit.
-Naturally, we hope that you will allow others to also redistribute
-your code, though you are not required to do so unless you
-use copyleft code (which is primarily found in the software
-contributed from the Free Software Foundation and is
-clearly identified).
-.LP
-Good luck and enjoy BSD.
