Ture, Kickfoot check out some of the links that Asteos posted. Then once you learn about unix look up some stuff about Linux. I am sure you can learn a lot, just takes some reading and later on experimenting. It's fun to learn a bout. If you get really serious about Unix and if you get in Linux , the Dummies book series are good starters. Unix for Dummies, then plenty of Linux for Dummies and Red Hat Linux for dummies. Any other links you want, ideas, etc do feel free to contact any of us.
