dupmerge - A Program for securely finding and optional linking/deleting duplicate files here.

It is written in C, runs on various platforms (Win32/64 with Cygwin, Unix, Linux etc.) and you can also find it in the grml repository: http://deb.grml.org/pool/main/d/dupmerge/.
You can find a tutorial here.

The original dupmerge author, Phil Karn, has rewritten the original version from scratch, with a new algorithm: http://www.ka9q.net/code/dupmerge/.
So there are now, since december 2008, two actual v

ersions of dupmerge: The karn and the freitag version.
