It is a good book but too soon out of date. I had Red Hat Linux 9 and managed to get it installed and setup using the book but shortly there after an upgrade came out which made the book somewhat out-of-date. I would not recommend purchasing this book; nor would I recommend most computer books. They are too expensive for the little use you will get from them. Also; the Linux developers seem to have shot themselves in the foot. They had a good product which to compete with Microsoft Windows but they did not pursue it. Now you cannt even find Linux operating system.
