I inherited an older edition of "UNIX Shell by Example" and agree it's 
a good book.  I'd also recommend O'Reilly's "Classic Shell Scripting" 

I probably shouldn't encourage this sort of thing, but you can find
the entire O'Reilly CD Bookshelf on the web if you want to sample
the books before buying.
