So I'm checking the md5 hash of my files with this as my output:

657cf4512a77bf47c39a0482be8e41e0  ./dupes2.txt

657cf4512a77bf47c39a0482be8e41e0  ./dupes.txt

8d60a927ce0f411ec94ac26a4785f749  ./derpina.txt

15f63928b8a1d5337137c38b5d66eed3  ./foo.txt

8d60a927ce0f411ec94ac26a4785f749  ./derp.txt

However, after running find . -type f -exec md5sum '{}' ';' | uniq -w 33 to find the unique hashes I get this:

657cf4512a77bf47c39a0482be8e41e0  ./dupes2.txt

8d60a927ce0f411ec94ac26a4785f749  ./derpina.txt

15f63928b8a1d5337137c38b5d66eed3  ./foo.txt

8d60a927ce0f411ec94ac26a4785f749  ./derp.txt

From my understanding, only one of either derpina.txt or derp.txt should be showing up since their hashes are the same. Am I missing something? Can anyone enlighten me as to why it outputs like this?
