Lists the jobs that you are running in the background and in the foreground. If the prompt is returned with no information no jobs are present.
syntax: jobs [-p | -l] [-n] [-p] [-x] [job id]

-p | -l Report the process group ID and working directory of the jobs.
-n Display only jobs that have stopped or exited since last notified.
-p Displays only the process IDs for the process group leaders of the selected jobs.
-x Replace any job_id found in command or arguments with the corresponding process group ID, and then execute command passing it arguments.
job id The job id.

Note: not all shells are capable of running this command.

Example:
jobs Would display results similar to the below if jobs were running in the background. [1] + Stopped (user) man jobs As you can see in the above job example the id is 1 it has been stopped by the user and the process in this case is man jobs (looking at the manual for jobs). jobs -l The above command would not just list the jobs running but also this group ID and the working directory of the jobs.
