\subsection wait-description Description
|
||
|
|
|
||
|
|
`wait` waits for child processes to complete. If a pid is specified, the command waits for that pid. If no pid is specified, the command waits for all background processes.
|
||
|
|
|
||
|
|
If the `-n` / `--any` flag is provided, the command returns as soon as the first subprocess completes. If it is not provided, it returns after all subprocesses complete.
|

|

|
\subsection wait-example Example
|
||
|
|
|
||
|
|
`sleep 10 & ; wait %1` spawns sleep in the background, and then waits until it finishes.
