That got me a little closer to an answer but I'm not sure how to
interpret the results.
ls -l gives me:
-rw-rw-r-- 1 mythuser root        44 2008-03-17 22:10 ??
ls -l | cat -etv gives me:
-rw-rw-r-- 1 mythuser root        44 2008-03-17 22:10 M-`M-sM-,$

But how do I interpret the non-printable characters in order to remove the file?

Thanks,
Richard
