bg — Move a job to the background
Format
bg [job…]
tcsh shell: bg [%job ...]
Description
bg runs one or more jobs in the background. The job IDs given on the command line identify these jobs, which should all be ones that are currently stopped. If you do not specify any job IDs, bg uses the most recently stopped job. It works only if job control is enabled; see the –m option of set for more information. Job control is enabled by default in the z/OS shell.
In
the tcsh shell:
- bg puts the specified jobs (or, without arguments, the current job) into the background, continuing each if it is stopped. job can be a number, a string, ", %, + or - .
- %job & is a synonym of the bg command.
