"Teach Yourself Unix in 24 Hours", 3rd edition, by Dave Taylor. Good for folks who want a structured approach. Links: author's page, example chapter, fatbrain.com, Amazon.
"Think UNIX", by Jon Lasser. A slightly more advanced introduction to Unix anno 2000. Links: author's page.
"The Unix Programming Environment", by Kernighan and Pike. A good introduction to Unix anno 1984. It's a bit like reading Middle English. Don't buy it new -- but if you find a copy cheap, read it to see what Unix looked like before graphics and the Internet, and what C programming looked like before ANSI C.
