fc -e - [old=new][command]
In the first form, a range of commands from first to last is selected from the last
HIST-
SIZE
commands typed at the terminal. The arguments first and last can be specified as a
number or string. A given string is used to locate the most recent command. A negative
number is used to offset the current command number. The
-l option causes the com-
mands to be listed on standard output. Otherwise, the editor program ename is invoked on
a file containing these keyboard commands. If ename is not supplied, the value of the
parameter
FCEDIT (default /usr/bin/ed ) is used as the editor. Once editing has
ended, the commands (if any) are executed. If last is omitted, only the command specified
by first is used. If first is not specified, the default is the previous command for editing and
−16 for listing. The
-r option reverses the order of the commands and the
-n option
suppresses command numbers when listing. In the latter, the command is re-executed
after the substitution old
=new is performed.
fg [ job ... ] Brings each job into the foreground in the order specified. If no job is specified, the current
job is brought into the foreground. See Jobs for a description of the format of job.
getopts optstring name
[arg ...]
Checks arg for legal options. If arg is omitted, the positional parameters are used. An
option argument begins with a
+ or a -. An option not beginning with +
or -, or the argu-
ment
-- ends the options. optstring contains the letters that getopts recognizes. If a
letter is followed by a :, that option is expected to have an argument. The options can be
separated from the argument by blanks.
getopts places the next option letter it finds inside variable name each time it is invoked
with a + preceding it when arg begins with a +. The index of the next arg is stored in
OPTIND. The option argument, if any, gets stored in OPTARG.
A leading : in optstring causes getopts to store the letter of an invalid option in
OPTARG, and to set name to ? for an unknown option and to : when a required option is
missing. Otherwise,
getopts prints an error message. The exit status is nonzero when
there are no more options. See also getopts(1).
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. (This is equivalent to print -r
