#panxor --- numerically XOR any arbitrary values
panxor applies the XOR operation; it is primarily meant to be used on top of a hashing utility like sha1sum(1).
For example, you can do something like
sha1sum FILES | panxor --stdin-hex --min-length 40 to XOR all of the hex hashes output by sha1sum into a single 40-character hex string.
This way, you can just check a single 40-character string as a sanity check --- like a poor man's git commit hash!
