Go Find Duplicates: blazingly-fast simple-to-use tool to find duplicate files
I use and test assorted duplicate finders regularly.
fdupes is the classic (going way way back) but it's really very slow, not worth using anymore.
The four I know are worth trying these days (depending on data set, hardware, file arrangement and other factors, any one of these might be fastest for a specific use case) are https://github.com/jbruchon/jdupes , https://github.com/pauldreik/rdfind , https://github.com/jvirkki/dupd , https://github.com/sahib/rmlint
Had not encountered fclones before, will give it a try.

Go Find Duplicates: blazingly-fast simple-to-use tool to find duplicate files
For example I maintain a tar file and a docker image with Kafka connectors which share many jar files. Using duphard I can save hundreds of megabytes, or even more than a gigabyte! For a documentation website with many copies of the same image (let's just say some static generators favor this practice for maintaining multiple versions), I can reduce the website size by 60%+, which then makes ssh copies, docker pulls, etc way faster speeding up deployment times.
