acid is right. Often times in linux you will need to do some reading and figuring on your own. Untarring/gunnzipping a file is a pretty basic procedure that you will find loads about all over the net. You will, in time, learn that finding out some info is pretty easy. Always start with
www.google.com/linux and your man pages. Then when you get stuck post here and people will come out of te woodwork to help you out. Good luck! I am glad you decided to take the plunge! Welcome to linux and the forum!
