How do I pause my shell script for a second before continuing?

Question

I have only found how to wait for user input. However, I only want to pause so that my while true doesn\'t crash my computer.

I tried pause(1)

Answer 1

You can make it wait using $RANDOM, a default random number generator. In the below I am using 240 seconds. Hope that helps @

> WAIT_FOR_SECONDS=`/usr/bin/expr $RANDOM % 240` /bin/sleep
