If anything should have been removed (or updated, actually) in old scripts were the references to "COMMAND". This was the name of the command processor under "Wintendo" systems (3.x, 9x, ME), after which it was replaced with "CMD" - the 32-bit enhanced version of the shell.
I think Glenn hit right on the head here.
Maybe my feeble mind is misleading me but I can't say I have ever seen anyone post a combination of the shell and find in the same line like that before. Very useful. Amazing how something I use elsewhere never popped into my mind to use with Kix.
