Comparing Files using Find and CMP

I needed to compare two directories containing binary files. Rsync was confusing, Diff only compares text-files.

I tried the following:

#!/bin/bash
# Example: ~/compare.sh FC30-3DA9
# where $1 is the directory name
# requirement: you are in one of the two parent dirs.
# the directories to compare must have the same name

find $1 -type f -exec sh -c '
  for f; do
    cmp "$f" /directory/of/mr/bear/"$f"
  done
' sh {} +

Seemed to work fine.
