>Anyone know of a linux program where it checks for duplicate images in a folder?
Have you tried googling? Last time I needed a script like this, I did a google search and the first result was what I needed.

I'm trying to learn "Linux" and I just read about find, sort and uniq today, so I was hoping someone would answer with a terminal command like you did.
If you don't mind telling, how long did it take you until you knew how to use these commands in such a complicated way? And how long is your beard?

It took about 30 seconds on google. No need to duplicate effort. It's all commands I use daily though

>>53905637
thanks for the answer. I guess it just takes experience to be able to use the CLI efficiently. So far I'm stuck with doing

man find
man sort
man uniq
...

and to give up and use a GUI ^^

The problem is I wanted a program where it shows me the duplicate images or similar images and I choose which one I delete.

>duplicate images
A GUI won't hell you in deciding whether you want to delete an image or the same image with a different name
>similar images
No wonder you couldn't Google it yourself, you don't even know what you want to ask

How about Webms/videos? Can you use the methods described here?

VisiPics + WINE

 fdupes -r -d DIRECTORY

I think these programs are a dime a dozen. They just check the sha-1 hash of each file and see if they can find it again.

-d lol

>>53905474 here, the first google result gave me exactly this.

Seriously, have you tried googling?
