Rdfind – redundant data find

Rdfind is a program that finds duplicate files. It is useful for compressing backup directories or just finding duplicate files. It compares files based on their content, NOT on their file names.

As of 20180326, the repository has been moved to Github. Signed releases are served here. Please use GitHub issues for bug reports, feature requests etc.

Install

There are official packages for most linux distributions. Use the package manager. For instance:

$ apt install rdfind # Debian/Ubuntu
$ dnf install rdfind # Fedora

If you are on Mac, you can install through MacPorts. If you are on Windows, you may use cygwin.

Documentation

Please see the man page (latest or 1.4.0) or the built in help (use the –help flag).

Without options, a results file will be created in the current directory and nothing will be removed.
