a screen of rmlint working


This is the old version of rmlint.
It has been rewritten in 2014 for many reasons. I keep this site only for nostalgic reasons.
Do not use the old version, it has bugs that will eat your hamster!
The old code can still be found here, if you like a good laugh:
Old releases

The new code can and documentation can be found here:
Source on GitHub
A commandline tool to find unnecessary files (duplicates, tmpfiles, unstripped binaries and more)



Only requirement is a POSIX-compilant Operating System, with a glibc version > ancient
Till now it has been succesfully tested on Linux 32/64bit OS.

rmlint was written carefully in the hope to be useful, but I don't give any warranty that it won't eat your data!
If this happens, and if it was due to a bug in rmlint, please
make a bugreport, so offers won't suffer from it!

A note about false positives:

Short: False Positves are actuallly possible, but very, very, very unlikely.
They would need to have the same size, fingerprint and checksums to be marked as twins.
md5 is not perfect, but the probability of getting false positves on a normal set of data is the same as lim(1/x) : x -> +inf = 0 + h; where h ~ 0

But isn't there a solution to be 100% sure? Yes, there is. It's the "--paranoid/-p" option. It does a
true byte-by-byte comparasion of each(!) file. Be warned, because it's incredibly slow.

What it does internally (Algorithm):

The algorithm tries to mimize IO as far as possible, thus focusing on CPU usage:

(Pseudo-)Speed comparasion:
