title: How to disable 'no crontab for user' message in shell
body: <p>I am doing this in my code</p>
  
  <pre><code>ssh -q username@ip 'crontab -l' &gt; $PWD/crontab.txt
  </code></pre>
  
  <p>If the server has <code>crontab</code>, there's no problem it works. But if that server does NOT have crontab I get the message <code>no crontab for username</code>.</p>
  
  <p>Is there a way to disable this message? When there is no crontab I don't want it to output anything.</p>
  
  <p>Thanks in advance</p>
