Syntax/Description Command
the entries. The
-d
option deletes the history entry at offset
OFFSET
.
The
-w
option writes out the current history to the history file;
-r
means to read the file and append the contents to the history list instead.
-a
means to append history lines from this session to the history file.
Argument
-n
means to read all history lines not already read from the
history file and append them to the history list.
jobs [-lnprs] [JOBSPEC ...]
job -x COMMAND [ARGS]
jobs
Lists the active jobs. The
-l
option lists process id's in addition to the
normal information; the
-p
option lists process id's only. If
-n
is
given, only processes that have changed status since the last notification
are printed.
JOBSPEC
restricts output to that job. The
-r
and
-s
op-
tions restrict output to running and stopped jobs only, respectively.
Without options, the status of all active jobs is printed. If
-x
is given,
COMMAND
is run after all job specifications that appear in
ARGS
have
been replaced with the process ID of that job's process group leader.
kill [-s sigspec | -n signum | -sigspec] pid | JOBSPEC ...
kill -l [sigspec]
kill
Send the processes named by PID (or
JOBSPEC
) the signal SIGSPEC.
If SIGSPEC is not present, then SIGTERM is assumed. An argument
of
-l
lists the signal names; if arguments follow
-l
they are assumed
to be signal numbers for which names should be listed. Kill is a shell
builtin for two reasons: it allows job IDs to be used instead of process
IDs, and, if you have reached the limit on processes that you can create,
you don't have to start a process to kill another one.
let ARG [ARG ...]
let
Each
ARG
is a mathematical expression to be evaluated. Evaluation is
done in fixed-width integers with no check for overflow, though divi-
sion by 0 is trapped and flagged as an error. The following list of op-
erators is grouped into levels of equal-precedence operators. The levels
are listed in order of decreasing precedence.
