With much regret, I had to remove these two programs - their license
doesn't permit us to distribute them. I think I should take some law classes... Explained by: bde

-Warsaw, 1998.10.21
-
-This is a port of Minix /bin/sh shell.
-
-It's quite limited, but also quite small. One of most serious
-limitations is lack of support for user-defined functions. Also,
-globbing should be implemented with our glob(3) - the version in
-sh4.c is rather primitive.
-
-This is a copyrighted software - see the file LICENSE. In short,
-it allows you to use it for research and educational purposes only.

-.SH DESCRIPTION
-.PP
-.I Sh
-is the shell, which forms the user's main interface with the system.
-On startup, the shell reads /etc/profile and $HOME/.profile, if they exist,
-and executes any commands they contain. The Minix shell has most of the
-features of the V7 (Bourne) shell, including redirection of input and output,
-pipes, magic characters, background processes, and shell scripts. A brief
-summary follows, but whole books have been written on shell programming alone.
-.LP
-Some of the more common notations are:
-.PP
-.in +2.45i
-.ta 2i 2.2i
-.ti -2.2i
-date # Regular command
-.ti -2.2i
-sort <file # Redirect \fIstdin\fR (standard input)
-.ti -2.2i
-sort <file1 >file2 # Redirect \fIstdin\fR and \fIstdout\fR
-.ti -2.2i
-cc file.c 2>error # Redirect \fIstderr\fR
-.ti -2.2i
-a.out >f 2>&1 # Combine standard output and standard error
-.ti -2.2i
-sort <file1 >>file2 # Append output to \fIfile2\fR
-.ti -2.2i
-sort <file1 >file2 & # Background job
-.ti -2.2i
-(ls \-l; a.out) & # Run two background commands sequentially
-.ti -2.2i
-sort <file | wc # Two-process pipeline
-.ti -2.2i
-sort <f | uniq | wc # Three-process pipeline
-.ti -2.2i
-ls \-l *.c # List all files ending in \fI.c\fR
-.ti -2.2i
-ls \-l [\fIa-c\fR]* # List all files beginning with \fIa\fR, \fIb\fR, or \fIc\fR
-.ti -2.2i
-ls \-l ? # List all one-character file names
-.ti -2.2i
-ls \e? # List the file whose name is question mark
-.ti -2.2i
-ls \(fm???\(fm # List the file whose name is three question marks
-.ti -2.2i

-.ti -2.2i
-echo $? # Echo exit status of previous command in decimal
-.ti -2.2i
-echo $$ # Echo shell's pid in decimal
-.ti -2.2i
-echo $! # Echo PID of last background process
-.ti -2.2i
-echo $# # Echo number of parameters (shell script)
-.ti -2.2i

-.ti -2.2i
-echo "$2" # Echo second parameter without expanding spaces
-.ti -2.2i
-echo $* # Echo all parameters (shell script)
-.ti -2.2i
-echo $@ # Echo all parameters (shell script)
-.ti -2.2i
-echo "$@" # Echo all parameters without expanding spaces
-.in -2.45i
-.LP
-The shell uses the following variables for specific purposes:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-SHELL the path of the current shell
-.ti -2i
-HOME the default value for the cd(1) command
-.ti -2i
-PATH the directories to be searched to find commands
-.ti -2i
-IFS the internal field separators for command strings
-.ti -2i
-PS1 the primary shell prompt
-.ti -2i
-PS2 the secondary shell prompt
-.in -2.25i
-.LP
-There are various forms of substitution on the shell command line:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-`...` Command string between back-quotes is replaced by its output
-.ti -2i
-"..." Permits variable substitution between quotes
-.ti -2i
-\&'...' Inhibits variable substitution between quotes
-.ti -2i
-$VAR Replaced by contents of variable VAR
-.ti -2i
-${VAR} Delimits variable VAR from any following string
-.in -2.25i
-.LP
-The expressions below depend on whether or not VAR has ever been set.
-If VAR has been set, they give:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-${VAR-str} Replace expression by VAR, else by str
-.ti -2i
-${VAR=str} Replace expression by VAR, else by str and set VAR to str
-.ti -2i
-${VAR?str} Replace expression by VAR, else print str and exit shell
-.ti -2i
-${VAR+str} Replace expression by str, else by null string
-.in -2.25i
-.LP
-If a colon is placed after VAR, the expressions depend on whether or not
-VAR is currently set and non-null.
-.LP
-The shell has a number of built-in commands:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-: return true status
-.ti -2i
-\&. fn execute shell script fn on current path
-.ti -2i
-break [n] break from a for, until or while loop; exit n levels
-.ti -2i
-continue [n] continue a for, until or while loop; resume nth loop
-.ti -2i
-cd [dir] change current working directory; move to $HOME
-.ti -2i
-eval cmd rescan cmd, performing substitutions
-.ti -2i
-eval rescan the current command line
-.ti -2i
-exec cmd execute cmd without creating a new process
-.ti -2i
-exec <|> with no command name, modify shell I/O
-.ti -2i
-exit [n] exit a shell program, with exit value n
-.ti -2i
-export [var] export var to shell's children; list exported variables
-.ti -2i
-pwd print the name of the current working directory
-.ti -2i
-read var read a line from stdin and assign to var
-.ti -2i
-readonly [var] make var readonly; list readonly variables
-.ti -2i
-set -f set shell flag (+f unsets flag)
-.ti -2i
-set str set positional parameter to str
-.ti -2i
-set show the current shell variables
-.ti -2i
-shift reassign positional parameters (except ${0}) one left
-.ti -2i
-times print accumulated user and system times for processes
-.ti -2i
-trap arg sigs trap signals sigs and run arg on receipt
-.ti -2i
-trap list trapped signals
-.ti -2i
-umask [n] set the user file creation mask; show the current umask
-.ti -2i
-wait [n] wait for process pid n; wait for all processes
-.in -2.25i
-.LP
-The shell also contains a programming language, which has the following
-operators and flow control statements:
-.PP
-.in +3.50i
-.ta 2i 3.25i
-.ti -3.25i
-# Comment The rest of the line is ignored
-.ti -3.25i
-= Assignment Set a shell variable
-.ti -3.25i
-&& Logical AND Execute second command only if first succeeds
-.ti -3.25i
-|| Logical OR Execute second command only if first fails
-.ti -3.25i
-(...) Group Execute enclosed commands before continuing
-.in -3.50i
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-for For loop (for ... in ... do ... done)
-.ti -2i
-case Case statement ((case ... ) ... ;; ... esac)
