sleep, pause
Synopsis:
sleep <seconds>
pause <seconds>
Description:
This suspends the client for the specified number of seconds. During this time,
the client does absolutely nothing; it quite literally goes to sleep. In general,
it is most useful in non-interactive automated scripts, and even these cases
are fairly rare. The only external difference between sleep and pause
is that sleep blocks. The client stops everything until it is done
sleeping. pause, however, only pauses execution of the current code block.
This allows the client to stop processing an alias temporarily without locking
the whole client up. There are other commands more suited to the tasks that
sleep is often used for. To wait a specified period of time before executing
a command, use timer. To wait indefinitely for a command or server query
to complete, use wait.
