The wait command man page simply states that it pauses script execution until a specified process ID completes. The man page for the sleep command is a single line stating that it causes a script to pause for specified period of time.

I use it sometimes inside scripts. Sometimes I need to kill a process then restart it. If you script that, the killing might not be finished before it restarts the process. So you put a sleep between them to give the system some time to kill te process.

The sleep command is used to suspend the execution of a shell script for the specified time. This is usually in seconds.
