Dave:
I appreciate the feedback. I've only been working out on shell utilities
for a while now, and am still quite green.
However, I think that it should be noted that there is (almost) always
more than one way to do things. I came up with a solution that worked,
ignore the fact that your's is far more efficient.
For doing what needs to be done, I would have used a perl script,
however, Susie (the person who asked for my help), didn't want to mess
with it that way. In a hurry, I came up with the script I posted.
It's good that you've posted a more efficient method, but the tone of
your post was quite rude. Perhaps it would have been better to start it
out with "Yeah, that works, but this is more efficient:"
