jobs - print currently running jobs

===================================

Synopsis
|
|
--------
|
|
|
|
::
|
|
|
|
jobs [OPTIONS] [ PID | %JOBID ]
|
|
|
|
|
|
Description
|
|
-----------
|
|
|
|
``jobs`` prints a list of the currently running :ref:`jobs <syntax-job-control>` and their status.
|
|
|
|
jobs accepts the following switches:
|
|
|
|
- ``-c`` or ``--command`` prints the command name for each process in jobs.
|
|
|
|
- ``-g`` or ``--group`` only prints the group ID of each job.
|
|
|
|
- ``-l`` or ``--last`` prints only the last job to be started.
|
|
|
|
- ``-p`` or ``--pid`` prints the process ID for each process in all jobs.
|
|
|
|
- ``-q`` or ``--query`` prints no output for evaluation of jobs by exit status only. For compatibility with old fish versions this is also ``--quiet`` (but this is deprecated).
|
|
|
|
On systems that supports this feature, jobs will print the CPU usage of each job since the last command was executed. The CPU usage is expressed as a percentage of full CPU activity. Note that on multiprocessor systems, the total activity may be more than 100\%.
|
|
|
|
Arguments of the form ``PID`` or ``%JOBID`` restrict the output to jobs with the selected process identifiers or job numbers respectively.
|
|
|
|
If the output of ``jobs`` is redirected or if it is part of a command substitution, the column header that is usually printed is omitted, making it easier to parse.
|
|
|
|
The exit status of ``jobs`` is ``0`` if there are running background jobs and ``1`` otherwise.
|
|
|
|
Example
|
|
-------
|
|
|
|
``jobs`` outputs a summary of the current jobs, such as two long-running tasks in this example:
