jobs

List active jobs.

Syntax
      jobs [-lnprs] [ jobspec ... ]

jobs -x command [ args ... ] Key -l List process IDs in addition to the normal information.
-p List only the process ID of the job's process group leader.
-n Display information only about jobs that have changed status since the
user was last notified of their status.
-r Restrict output to running jobs.
-s Restrict output to stopped jobs.

The first form lists the active jobs.

If jobspec is given, output is restricted to information about that job. The return status is 0 unless an invalid option is encountered or an invalid jobspec is supplied.

If the -x option is supplied, jobs replaces any jobspec found in command or args with the corresponding process group ID, and executes command passing it args, returning its exit status.

jobs is a bash built in command: $ help jobs
