jobs [ -lnp ][job ... ]
Lists information about each given job; or all active jobs if job is omitted. The
-l option
lists process ids in addition to the normal information. The
-n option only displays jobs
that have stopped or exited since last notified. The
-p option causes only the process
group to be listed. See Jobs for a description of the format of job.
kill [ -sig ] process ...
Sends either the TERM (terminate) signal or the specified signal to the specified jobs or
processes. Signals are given either by number or name (as given in signal(5), stripped of
the prefix
SIG). The signal names are listed by
kill -l. No default exists; merely typ-
ing
kill does not affect the current job. If the signal being sent is
TERM (terminate) or
HUP (hangup), the job or process is sent a
CONT (continue) signal when stopped. The pro-
cess argument can be either a process ID or job. If the first argument to
kill is a nega-
tive integer, it is interpreted as a sig argument and not as a process group. See also kill(1).
let arg ... Each arg is a separate arithmetic expression to be evaluated. See Arithmetic Evaluation
above, for a description of arithmetic expression evaluation. The exit status is 0 if the value
of the last expression is nonzero, and 1 otherwise.
% newgrp [ arg ... ]
Equivalent to exec newgrp arg ....
print[ -Rnprsu[n]] [arg ... ]
The shell output mechanism. With no options or with option - or -- the arguments are
printed on standard output as described by echo(1). Raw mode, -R or -r, ignores the
escape conventions of echo. The
-R option prints all subsequent arguments and options
other than -n. The -p option causes the arguments to be written onto the pipe of the pro-
cess spawned with |& instead of standard output. The -s option causes the arguments to
be written onto the history file instead of standard output. The -u option can be used to
specify a one-digit file descriptor unit number n on which the output is to be placed. The
default is 1. If the option -n is used, no newline character is added to the output.
pwd [-L-P ]
With no arguments prints the current working directory (equivalent to print -r -
$PWD
). The -L option (default) preserves the logical meaning of the current directory and
-P preserves the physical meaning of the current directory if it is a symbolic link. See the
special cd command, cd(1), ln(1)), and pwd(1).
read [ -prsu[n]] [name ][?prompt ][name ...]
The shell input mechanism. One line is read and broken up into words using the charac-
ters in
IFS as separators. In -r raw mode, \ at the end of a line does not signify line
continuation. The first word is assigned to the first name, the second word to the second
name, etc., with remaining words assigned to the last name. The -p option causes the
input line to be taken from the input pipe of a process spawned by the shell using
|&.If
the
-s option is present, the input is saved as a command in the history file. The option
-u can be used to specify a one-digit file descriptor unit to read from. The file descriptor
can be opened with the exec special command. The default value of n is 0.Ifname is
omitted,
REPLY is used as the default name. The return code is 0, unless an end-of-file is
encountered. An end-of-file with the -p option causes cleanup for this process so that
another process can be spawned. If the first argument contains a ?, the remainder of this
word is used as a prompt when the shell is interactive. If the given file descriptor is open
for writing and is a terminal device, the prompt is placed on this unit. Otherwise the
prompt is issued on file descriptor 2. The return code is 0, unless an end-of-file is encoun-
tered. See also read(1).
%% readonly [ name[ =value ] ... ]
The given names are marked read-only and these names cannot be changed by subsequent
assignment.
% return [ n ]
Causes a shell function to return to the invoking script with the return status specified by
n.Ifn is omitted, the return status is that of the last command executed. Only the low 8
bits of n are passed back to the caller. If return is invoked while not in a function or
executing a script by the . (dot) built-in command, it has the same effect as an exit com-
mand.
