File Manager Picture Compare

Raevyn · 05-08-2015, 09:39 PM

Hello,

I was curious if anyone knows of a picture comparison tool available that can scan the file system looking for pictures that may be identical?

identical pictures should have same size, anyway you are looking for tool or command that finds dupicated files on your hard drive, there should be plenty of information about that online.

As helpful as saying "go Google for it".
Please don't.

Identical files have identical checksums (MD5, SHA1, etc, etc). Finding files was often called "lint checking". See our own sahib_bommeligs rmlint, fslint, fdupes or http://en.wikipedia.org/wiki/List_of...e_file_finders.

...plus there's ImageMagick compare but you may or may not want to go there ;-p

fdupes.
CLI, fast for what it has to do (MD5SUM), and has useful options for deleting. Of course if you have multiples (backups) under different directories, the auto delete is dangerous. At least you get the list you can then run a script over.
The Ubuntu manpages give some examples that explain how to use -r and -R - really useful examples that should be in the base package IMNSHO.

I just installed fslint (thank you) to see if that may work

Also, I did try Google but the problem I was running into was it pulling results to compare to pictures side by side to look for pixmap differences, NOT duplicated picture downloads.

This is my duplicate file finder:

By default it just shows you files with byte-identical sizes, which is actually accurate close to 100 percent of the time.
