in thread Bitwise comparision of files

As I mentioned in parentheses, the advantage of using the checksumming technique is that the directories don't need to be accessible from the same machine.

Whether that matters here, I don't know, but I figured it might perhaps be useful to someone, sometime.

    Then I'd use something like rsync -rcn directory1 remote:directory2

      The checksumming approach is still more flexible.

      Example scenario:  a friend phones you for help with a software problem.  At some point while discussing the issue, you'd like to verify that s/he is actually using the same versions/files, because you can't replicate the problem on your side.  So, you create a checksums file of the installation tree and email it to your friend, who can then run the verification without needing any access to your machine whatsoever.
