There is one "classic" Unix introduction book that I can strongly recommend, and that you can probably buy used for a dollar: Exploring the Unix System by Stephen Kochan and Patrick Wood. Make sure to get the paperback edition that is about 400 pages. Also, apparently the authors are going to release an updated version of that book -- check http://www.kochan-wood.com for updates.
