List hardlinks on HFS volumes

This one goes out to all of you mac users out there.

I recently made a little hack hardlinks that takes a path (or inode) of a hardlinked file and lists the paths of all of its clones (including its own), provided it lives on an HFS volume. Usage is simple:

sudo hardlinks path

or

sudo hardlinks -c inode

You need to have the hfsdebug-lite binary Amit Singh provides installed for it to work, and if you're on a modern mac, you need to install the Rosetta tools from your MacOS X install disk to get hfsdebug to run. (That sudo is needed for hfsdebug to access the raw device of the volume -- after that, hfsdebug drops privileges to the nobody user.)
