No need to define "cmd-foo" anchors; use :doc:`foo <cmds/foo>`
instead. If we want "cmd-foo" but it should be tested.

Description

|
|
|
NOTE: This page documents the fish builtin ``wait``.
|
|
To see the documentation on any non-fish versions, use ``command man wait``.
|
|
|
|
``wait`` waits for child jobs to complete.
|
|
|
|
If a *PID* is specified, the command waits for the job that the process with that process ID belongs to.
|
|
|
|
If a *PROCESS_NAME* is specified, the command waits for the jobs that the matched processes belong to.
|
|
|
|
If neither a pid nor a process name is specified, the command waits for all background jobs.
|
|
|
|
If the **-n** or **--any** flag is provided, the command returns as soon as the first job completes. If it is not provided, it returns after all jobs complete.
|
|
|
|
The **-h** or **--help** option displays help about using this command.
