I don't know if you can make a computer do anything while it is sleeping. It usually pauses all PROCESSES so it can ENTER a low POWER state.
You're not trying to create a screensaver are you?It's not that kind of sleeping michaewlewis... its a sleep command in a script.
I.e. he wants the script to pause for a SET time.

fanco it would probably help with some more details... including what kind of scripting language you're using.Quote from: fanco on October 04, 2007, 10:12:39 AM

Code: [Select]t=$(date +%S)
t=`echo $t+120 |bc`
echo "this program will end in 2 minutes from now"
sleep $t
exit
