disown: disown [-h] [-ar] [jobspec ...]

Remove jobs from current shell.

Removes each JOBSPEC argument from the table of active jobs. Without any JOBSPECs, the shell uses its notion of the current job.

Options
-a remove all jobs if JOBSPEC is not supplied -h mark each JOBSPEC so that SIGHUP is not sent to the job if the shell receives a SIGHUP -r remove only running jobs

Exit Status:
Returns success unless an invalid option or JOBSPEC is given.
