title: Linux command to generate new GUID?
body: <p>Sometimes in bash scripting, i need to generate new <code>GUID(Global Unique Identifier)</code>.</p>
  
  <p>I already done that by a simple python script that generates a new guid: see <a href="https://stackoverflow.com/questions/534839/how-to-create-a-guid-in-python">here</a></p>
  
  <pre><code>#! /usr/bin/env python
  import uuid
  print str(uuid.uuid1())
  </code></pre>
  
  <p>But i need to copy this script into any new system that i works on.</p>
  
  <p><strong>My question is</strong>: can anybody introduce a command or package that contains similar command ?</p>
