Linux shell script FAQ: Can you share a Linux shell script while loop example? While you're at it, can you show how to use the sleep command in the shell script while loop?
Sure. As a little background, I've written a program I call an Email Agent that periodically scans my email inbox, and does a lot of things to the inbox, including deleting the over 6,000 spams that I receive in a typical day. A recent problem with the Agent is that it runs too fast, apparently overwhelming the sendmail process on the machine that it runs on.
