Jared,
Thanks for the summary. Any comments on where Tcl fits in to the mix?

Let me start off by saying that I like Java. I took a class
in it from Sun, and Java is easy. Learning the libs is hard
but the language is easy.
I'm going to say something now that may sound counter intuitive:
Learn Perl first. The reason it may seem counter intuitive is
that Perl is hard to learn, at least at first. Much easier if
you've had exposure to C though.
The reason for learning Perl is that there are many tasks that
are easy in Perl that are hard in Java. It's the same old balance:
with power comes complexity.
The basics of Perl aren't really *too* hard, just take a little
getting used to.
The payoff is big. There is no better language for data munging
than Perl. If you need to clean up data for SQL loader files,
use Perl. Don't try to do it with PL/SQL or Korn as it is just
too much work.
While SQL*Loader allows you to do some very complex things in it,
it is *very* difficult at times. Clean your data first.
Need to deal with a lot of text files, search for errors in log
files, etc., do it with Perl.
You will also be able to develop Perl code much faster than you
can develop Java code. Java is very wordy, Perl can be very
terse if you want or require.
Perl makes hard things easy, and impossible things possible. :)
see www.perl.com for articles, downloads and tutorials.
Good first books for the non-programmer are Learning Perl and/or
Learning Perl for Win32.

Well, you've got the right idea, just in the
wrong order.
The korn shell does not compile the whole script
and then execute as say Perl does.
It executes it a line at a time.
So rearrange your script like so:
==
#!/bin/ksh
function quick_test {
echo hello
}
echo supposed to show hello below
quick_test
==
and it will work.
Might be a good idea to pick up a good Korn
shell book. O'Reilly has one I believe.
I like the one by Kochan and Wood, published
by Hayden books.

Re: dumn unix script question
While on the one hand I completely agree, as in my opinion Perl is the absolutely bestest, yummiest and downright smartest language I've ever encountered -- if you learn it first, you'll never be satisfied or happy in any other language again ever. ;-) Also, as a learning language, it can be confusing because any given problem has as many possible solutions as there are programmers. Learners tend to want to know one way to do things at first. I taught a couple of Perl classes and all of my students suffered from information overload. That may have been that I was a poor teacher...yeah, that was probably it. I was also so enthusiastic about the logic and linguistics of Perl that I think I talked over their heads.
