	Ah, but it's fun to see how many piped commands you can run on one
command line.  I remember we had to do some thrashing of data from an
Oracle database to find out what records were out of sync with the LDAP
server (don't ask, I just did the hacking; I have no idea what the heck
they were doing with a setup like that).  Anyway, we also wanted to try
and not reuse the same command twice.  We almost made it.  We ended up
using grep x 2, sed, awk, perl & tr.
