[PLUG] bash reference books

[Rich Shepard]

   I have a first edition (1995) of "Learning the bash Shell" and it's time
to get a newer reference. I see that Powell's has more than the ORA edition
(now in it's third iteration), and I'm seeking recommendations whether to
buy the ORA version or one of the others.

   Any opinions here? (Rhetorical question, eh?)
