Ubuntu – How to find (and delete) duplicate files


I have a largish music collection and there are some duplicates in there. Is there any way to find duplicate files. At a minimum by doing a hash and seeing if two files have the same hash.

Bonus points for also finding files with the same name apart from the extension – I think I have some songs with both mp3 and ogg format versions.

I'm happy using the command line if that is the easiest way.

  • I use fdupes for this. It is a commandline program which can be installed from the repositories with sudo apt install fdupes. You can call it like fdupes -r /dir/ect/ory and it will print out a list of dupes. fdupes has also a simple Homepage and a Wikipedia article, which lists some more programs.
