For checking that a backup is complete, or checking that I have all the files from a camera SD card (before I wipe the card) it would be useful to be able to run duff in a "find unique" mode that lists files which don't have duplicates.
As ever, this functionality can be constructed with an appropriate pipeline of find/sha1sum/sort/uniq or similar, but perhaps it's close enough to what duff does to be worth including?
