I just wanted to say thanks to Ross for reminding folks on the list
about the existence of the venerable (g)awk.

I think a lot of folks would be pleasantly surprised about its power and
simplicity of use, if one is already regex familiar.

Personally, in many years of use, I feel I still do not need to learn
Perl (although I did get a book and dabble with it some) for 99.9% of
things that *I* do.

Awk does the job for me.
