title: Crontab is not running on mac osx 10.9.3
body: <p>I would like to open a URL using crontab in the terminal every minute for example. I also tried "cronnix" and "lingos" but non of the methods work. My mashine simply does not execute the command. I did </p>
  
  <pre><code>crontab -e
  </code></pre>
  
  <p>then I inserted the line</p>
  
  <pre><code>1 * * * * open http://www.google.de/
  </code></pre>
  
  <p>terminal says it is installing the new cron job. But then nothing happens. What do I have to do? Thanks.</p>
