Consider what happens if I: mkdir -p "duh\n/etc" touch "duh\n/etc/passwd" Bingo. Bye bye password file. A better solution is a Perl solution (since you cross-posted to clpm, I take it Perl is fair game here): find2perl <dirs> -size 0 -type f -eval unlink | perl Much safer. No chance to misinterpret a newline as a delimiter. Perl is your friend. Use Perl. print "Just another Perl hacker," -- Name: Randal L.
