Most unix or Linux admins come across regular expressions occasionally. It is very powerful to handle text with and if you have understood it once it is handy to have an on-line reference source to quickly to lookup the syntax for what you want todo. My problem is that I always forget the syntax 🙂
Take a peak at the excellent page http://www.regular-expressions.info/ to learn more about regular expressions.

Sites like http://www.solmetra.com/scripts/regex/ is a lifesaver sometimes 😉
