Description
|
|
-----------
|
|
|
|
``wait`` waits for child jobs to complete.
|
|
|
|
- If a pid is specified, the command waits for the job that the process with the pid 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`` / ``--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.
