While driving around the Information Highway today with the AC on to
stay cool, I noticed an interesting offramp sign so I exited to find
the following which is a more recent version than I, and perhaps you,
already have:

This document is both a tutorial and a reference on shell
scripting with Bash. It assumes no previous knowledge of
scripting or programming, but progresses rapidly toward an
intermediate/advanced level of instruction . . . all the while
sneaking in little nuggets of UNIX® wisdom and lore. It serves as
a textbook, a manual for self-study, and as a reference and
source of knowledge on shell scripting techniques. The exercises
and heavily-commented examples invite active reader
participation, under the premise that the only way to really
learn scripting is to write scripts.
This book is suitable for classroom use as a general introduction
to programming concepts.
Lots of other extremely useful free books are listed on the same page.
