title: Simple Python shell wrapper script (using os.execv?)
body: <p>I want to add a wrapper around a specific shell command.  This will run in Linux only and I don't care about cross platform support.  This code works, but is there a better way to achieve this?  Or am I opening myself up to any weird behavior?</p>
  
  <pre><code>import os
  import sys
  
  # Do my personal validation here
  do_some_validation(sys.argv) 
  
  # Now call the real program
  os.execv('/usr/bin/some-command', sys.argv)
  </code></pre>
  
  <p>Thanks!</p>
