Amazing stuff.
I needed to do some of these set operations at work in a jiffy and this page helped a lot. It has been a while since I did much stuff in Unix (10 years) and had forgotten most of it and how powerful it can be. I think I should get a book and get back into Unix and unleash the power of the shell. Perhaps this time, I would get around to learning awk.

Thank you!
