rmlint finds space waste and other broken things on your filesystem and offers to remove it.

Features:

Finds…

• …Duplicate Files and duplicate directories.
• …Nonstripped binaries (i.e. binaries with debug symbols)
• …Paranoia mode for those who do not trust hashsums.
• …Broken symbolic links.
• …Empty files and directories.
• …Files with broken user or/and group ID.

Differences to other duplicate finders:

• Extremely fast (no exaggeration, we promise!).
• Many output formats.
• No interactivity.
• Search for files only newer than a certain mtime.
• ...

Due to some of it's performance optimizations, it currently only runs on Linux 32 and 64 bit. Porting to BSD and Darwin (Mac OSX) architectures is possible though, but needs some volunteers to test. Patches welcome!

It has been compiled and run successfully on FreeBSD, although it cannot use fiemap and mounttables as performance optimizations there. Patches to make this run better over there are welcome too.

Chances are that you might have rmlint already as readily made package in your favourite distribution. If not, you might consider compiling it from source.
