Go for it.

I have not read it, but how beneficial it will be is probably not
related to its age, just its overall quality.

Bash is most similar to the Bourne shell. Bash is the "Bourne Again
SHell" :-)

If it's a good book, you'll do well to read it.
IMHO the best introduction to shell programming and UNIX in general is
still "The UNIX Programming Environment" by Kernighan & Pike. It was
written in 1978! I love the book, and if some one added a sticky note
in there describing the '#/bin/sh' syntax supported my modern shells
it would be a pretty complete introduction to the UNIX philosophy.
Cheers!
