Check These Out

This dup finder saves time by comparing size first, then md5sum, it doesn't delete anything, just lists them.

list unique file extensions recursively for a path, include extension frequency stats
Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')

Don't copy trailing '=' or use head -c to limit to desired length.
