Check your dropbox.com files' md5sums across 2 (or more) Linux PCs

The first thing to do is to gather all the md5sums from one server, say Server BLUE.

• [username@BLUE]$ cd ~username/Dropbox/
  [username@BLUE]$ find . -mmin +60 -type f -exec md5sum {} \; > .md5sums
  

Now lets head over to Server RED and see if the checksums match!

• [username@RED]$ cd ~username/Dropbox/
  [username@RED]$ md5sum -c .md5sums |grep -v OK    
  

You can run this without the grep, but it is a bit noisy
