No Boyd, I wouldn't recommend doing that. Sounds like you need to read Kernighan and Plauger's _Software Tools_ where they discuss sort's -u option. It happens to be "more efficient" to put this particular function into the sort program.

In this case for the user as well as the machine. I'd recommend _Software Tools_; it's a great book. You'll like it. Adieu, Ralph.
