So I ran into a little problem the other day, when I spliced together two folders of wallpaper and ended up with a bunch that were probably the same.
Rather than riffle through them one by one and delete the duplicates, I dug around a little on the Internet and found fdupes.
Simple enough, fdupes checks file sizes, MD5 sums and does byte-by-byte comparisons, and where it finds similarities, it spits out the name.
To add to the fun though, you can trigger an interactive mode, and fdupes will eradicate the ones that you decree.
Exactly what I needed to solve my problem: I get a short list of files that are most likely identical, I pick the one I don’t want, and fdupes takes care of the rest.
For every task, there is a perfect tool. 😈
