==Commands==

{{Missing information|section|wait|date=April 2021}}

The POSIX standard specifies two commands for resuming suspended jobs in the background and foreground, respectively {{mono|bg}} and {{mono|fg}}. These were modeled after the Korn shell job control commands.<ref>{{man|cu|bg|SUS}}; {{man|cu|fg|SUS}}.</ref>

The command {{mono|[[wait (command)|wait]] [''jobid list'']}} pauses until the background tasks in the list have completed. All tasks must be running in the current shell. If the jobid list is empty then the pause continues until all outstanding background tasks are completed.<ref>{{cite web | last=Kerrisk| first=Michael |date=Feb 2, 2025 |title=wait(1p) — Linux manual page|url= |website=man7.org |url=https://www.man7.org/linux/man-pages/man1/wait.1p.html |publisher= |access-date=May 13, 2025}} </ref>
