title: bash equivalent for os.walk?
body: <p>I am using 2to3 to fix my script library, and it seems to be a command line thing, not a shell thing.</p>
  
  <p>I want to do all files from /home/me/scripts downward, assuming they end in <code>.py</code>. Is there an easy way to do 2to3 -y filename for each file under my folder in the shell?</p>
