Waits for a specified amount of time in a batch file

Sometime in a batch file you need to wait to ensure that enough time is given for some operations to complete (installation, configuration, etc.)

There are some ways and tricks to put a pause, if you have a specific time a good solution is use the Sleep.exe utility.

This utility is available with the Windows Server 2003 Resource Kit Tools .  Useful in batch files, Sleep.exe waits for a specified amount of time.

Usage:

sleep time-to-sleep-in-seconds
sleep [-m] time-to-sleep-in-milliseconds
sleep [-c] commited-memory ratio (1%-100%)

Example :
sleep 5 ( waits for 5 seconds )
