Find and remove Duplicate files

[meat]

I recently had some issues where I thought I had some bad hard drives but it ended up being an issue with the server itself - either the backplane or controller.  I ended up putting my drives back into my old server and was able to get everything back to 100% however, before doing so, I had moved several files from the emulated disk onto a good disk.  Long story short, I now I have several duplicate files.

 

I saw there is a script to handle this, however it was written 10 years ago and a lot has changed in unRAID since then.  Are there any built in tools or any new scripts that people use to handle duplicates?

 

thanks
