7.6. Job Control
Job control lets
you place foreground jobs in the background, bring background jobs to
the foreground, or suspend (temporarily stop) running jobs. Job
control is enabled by default. Once disabled, it can be re-enabled by
any of the following commands:
bash -m -i
set -m
set -o monitor
Many job control commands take jobID as an
argument. This argument can be specified as follows:
- %n
-
Job number n
- %s
-
Job whose command line starts with string s
- %?s
-
Job whose command line contains string s
- %%
-
Current job
- %+
-
Current job (same as preceding)
- %-
-
Previous job
bash provides the following job
control commands. For more information on these commands, see Section 7.7 earlier in this chapter.
- bg
-
Put a job in the background.
- fg
-
Put a job in the foreground.
- jobs
-
List active jobs.
- kill

- stop

- stty tostop
-
Stop background jobs if they try to send output to the terminal.
- wait
-

- Ctrl-Z
-
Suspend a foreground job, and use bg
or fg to restart it in the
background or foreground. (Your terminal may use something other than
Ctrl-Z as the suspend
character.)
