fdupes

fdupes is a great little Linux utility that can do a checksum comparision of files recursively across folders and print a list or matches (or alternatively delete matches)

I discovered it whilst cleaning out my mp3 collection the other night (see the "find" article)

Even across a 100GB mp3 collection with 20odd thousand files it gave me a list of duplicates pretty quick. Because this is a checksum comparision duplicates with differnet filenames are discovered but they must be exactly the same. Doing this cleared about 5GB of space from my collection in minutes.

Cool stuff and another great little sysadmin tool.
