Since a parent waitpids for its child for all but backgrounded commands, the built-in wait only has to wait for any backgrounded commands (if there are any). Take the following example, sleep 15 is backgrounded and then "wait" waits for sleep 15 to finish before returning.


[xxx@bumblebee hwk5]$ /c/cs323/Hwk5/bashLT
(1)$ sleep 15 &
Backgrounded: 618997
(2)$ wait
Completed: 618997 (0)
(3)$
