I have the hard copy and ebook, and it's great. I've been using some type of ∗nix OS since the late eighties, and I will never learn the whole thing. Unix Power Tools is one of the few door-stop sized books that are worth having. A few of the items are somewhat dated, but ∗nix today, at least what's covered in UPT, is mostly what ∗nix has always been. EDIT: changed ascii asterisk in front of all instances of nix to u+2217, the plain asterisk translates to large bodies of italicized text on HN. Which I knew.
