fdupes is a simple, mature, and fast tool for helping you identify and remove duplicate files and directories. It’s an excellent way to prune a media collection such as a photo library.
fdupes can follow symlinks and can be instructed to ignore hardlinks.
There are other tools that perform a similar function to fdupes. But this is the one which we use the most.
