A utility to find and clean "lint" on a filesystem
http://www.pixelbeat.org/fslint/

This package is based on the package 'fslint' from project 'home:mrdocs'.

FSlint is a utility to find redundant disk usage like duplicate files
for example. It can be used to reclaim disk space and fix other problems
like file naming issues and bad symlinks etc.
It includes a GTK+ GUI as well as a command line interface.
