There's also
Czkawka, which is a very powerful GUI tool for managing duplicates and "similar images", among other nifty features.
It also has a CLI version (which is suited for SSH sessions.) Not sure how intuitive the CLI version is (since I only use the GUI frontend.)
It's available as a FreeBSD port or binary package:
Czkawka (tch-kav-ka, hiccup) is a simple, fast and free app to remove unnecessary files from your computer. Features: - Written in memory safe Rust - Amazingly fast - due to using more or less advanced algorithms and multithreading - Cache support - second and further scans should be a lot...

pkg install czkawka
Fun fact: "czkawka" is Polish for "hiccup".

Neat!
So why didn't they just name the application "Hiccup" or "Lint Hunter" or "Dupe Finder" or something cool and intuitive?
Because they want you to pull your freaking hair out trying to search for it online. What better way to brand your software than to make it a frustrating hurdle to discover? Do you know how many times I started my search with "ckw-" or "cwa-" or "caw-"?
