wait [-n | --any] [PID | PROCESS_NAME] ...

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.
