title: Stop python script with crontab
body: <p>If I start a python script every twelve hours with this crontab:</p>
  
  <pre><code>0 1,13 * * * /usr/bin/python script.py
  </code></pre>
  
  <p>Then how do I stop the script running inbetween?</p>
  
  <p>I.E. I want the python script to start at 1am and 1pm, but stop the script at 6am and 6pm.</p>
  
  <p>I'm doing this to get around the fact that making a particular script I have go to sleep for 6-12 hrs a day is proving beyond me! It seems better to hand the process over to the system itself.</p>
