Hey everyone I've returned. I have not had much success on learning Linux with the DVD's I purchased. The guy just talks a lot and does not show any examples. So I have no idea what he is talking about. I have Ubuntu and CentOS both installed and I'm just wondering how should I go about learning Linux. I would like to learn Linux good enough to become a system admin, but what should I do to start? Buy a book on specifically about Linux? I use Ubuntu everyday.
