Synopsis
|
|
--------
|
|
|
|
.. 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 options:
|
|
|
|
**-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).
|
|
|
|
**-h** or **--help**
|
|
Displays help about using this command.
|
|
|
|
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
|
|
-------
|
|
