Also on the tldp site is a 'beginner's BASH guide' - in fact there are a number of guides:

Unfortunately a lot of the stuff has not been updated in 5 yrs or so - but it is still fun to read through from time to time.

It is not exactly a BASH guide but another good guide is "UNIX for Poets" - I think there have been a number of news.ycombinator posts regarding it. This is a good intro for the text manipulation tools you would tend to use in a BASH script.
