Before you break your head over trying to understand why the code works, here are a few notes (if you are training for the obfuscated shell contest, don't read on): The -c option makes sure all nodes exist, even if the glob is failing. So you might end up with empty files like '*' or '.??*'. local variables are not supported by POSIX. We get away with using a recursive function anyway because it is mostly tail recursive. The only problem is the "rmdir $f", which comes after the recursion and uses a local variable. The dirname $f makes up for this case, because the only thing that happens after the recursion is that $f has a path element more than before. It is black magic, but it seems to work :) Thanks, Marcus -- `Rhubarb is no Egyptian god.'
