Joe,
Along with everything else you've heard so far, you may want to read the
man page for your shell of preference. I would add that O'Reilley's also
carries shell programming books.

As you may have surmised, Unix has a rich environment for automating
tasks. Dig in, and you will find the one that works the best for you. 

Bob
