I should add one more small pitch for Ramesh Natarajan’s “Linux 101 Hacks,” which is available for download at The Geek Stuff for the grand price of nothing. I checked it out this morning and found it quite interesting. There are a lot of tricks in there that I hadn’t heard of, or perhaps just hadn’t thought of.
Of course, if you’re a terminal hater you’ll want to steer clear of that since, there’s very little offered that will keep you at the GUI level. On the other hand, if you’re not afraid to let go of your mouse, I would suggest checking it out.
