Well, since CGF himself didn't deem this too off-topic... :-)

Nope. Try the above -- only the names *without* underscores will be
*printed*, since \*_\* will match them first, and wisk them away from the
second match expression.

The above has a bug -- it should have a "-a" instead of a "-o". Once
that's fixed, that would be YA way of doing it. The parentheses aren't
neded. BTW, this suffers from the same problem as my original suggestion

Or you could add "-mindepth 1 -maxdepth 1" to the "find" command above,
which would make it do exactly what the user wanted.

P.S. Should I add TMTOWTDI to the OLOCA? ;-)
