Hi, Randy,

Umm, no, we're not going for convolutedness here, we're trying to figure
out how to do an equivalent of globbing without actually expanding the
whole thing on the command line...

You're right about the "./" being prepended to the output of find, and so
I agree with the "sed" suggestion (except that I'd modify it to "sed
's@\./@@'" to avoid an extra backslash).  I'll have to disagree with the
-d, however, since the original command ("ls *") *will* list the contents
of each subdirectory (as opposed to the plain "ls", which won't).
	Igor
P.S.  Geez, 25 years?  You beat me by 2.5x... :-)
