So, I recently found a nifty piece of software called FSlint. Now, I’ve only gotten to the surface of its capabilities, but I use it to find duplicate or similar files in directories. It’s available in Debian with a good ole
sudo apt install fslint and it has been working great in directories in excess of 6000 files.
Here’s a screenshot of it working recursively in my $HOME. It shows similar files, how much wasted space there is as a result, and gives me options to delete duplicates, create symlinks for them, and more!!! Definitely a powerful tool if any of you are interested.
