# wait - wait for jobs to complete

## Synopsis

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

## 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.

## Example

    sleep 10 &
    wait $last_pid

spawns `sleep` in the background, and then waits until it finishes.

    for i in (seq 1 5); sleep 10 &; end
    wait

spawns five jobs in the background, and then waits until all of them finishes.

    for i in (seq 1 5); sleep 10 &; end
    hoge &
    wait sleep

spawns five jobs and `hoge` in the background, and then waits until all `sleep`s finish, and doesn't wait for `hoge` finishing.
