Good point. I was thinking in more general terms, and hadn't considered 
'at has been moved accidentally but still exists'.

I was working on a machine recently that lacked a 'which' command, and 
kept commands in REALLY STRANGE places. So I tried
	locate cmdname | egrep '/cmdname$'
.... but got the horrifying error:

locate: not found
egrep: not found

It was egrep that impressed me. This was OpenServer 5.0.2 and must've 
been a basic or cut down install to omit egrep. Locate is apparently a 
Linux and BSD only thing, or at least only recent on other UNIXes. *sigh*.
