Job control is a process manipulation feature found in the Korn shell. It allows programs to be stopped and restarted, moved between the foreground and background, their processing status to be displayed, and more. To enable job control, the monitor option must be enabled. By default, this is enabled on systems that support the job control feature. When a program is run in the background, a job number and process id are returned.
