Hi, Brian:
Thanks. Your suggestion is the similar to Jim's with
the arguments reversed.
You and Jim have fed me. Thanks.
Please teach me to fish. ;-)
I don't understand the '-f1' and '-f2' arguments.
IMHO, 'man cut' and 'info cut' are equally obfuscating:
-f, --fields=LIST
output only these fields
duh, what!
Please briefly explain.
Regards, Chuck
