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 any of the following commands:
jsh -i Bourne shell ksh -m -i Korn shell (same as next two) set -m set -o monitor
Job whose command line starts with string
Job whose command line contains string
Current job (same as above).
The Bourne and Korn shells provide the following job control commands. For more information on these commands, see "Built-in Commands" earlier in this section.
Put a job in the background.
Put a job in the foreground.
List active jobs.
Terminate a job.
Suspend a background job.
Stop background jobs if they try to send output to the terminal.
Same as CTRL-Z.
Wait for background jobs to finish.
Suspend a foreground job. Then use bg or fg. (Your terminal may use something other than CTRL-Z as the suspend character.)
