title: Can I run a command in background on server by exec_command of paramiko?
body: <p>I use the <code>exec_command</code> of <a href="http://www.lag.net/paramiko/" rel="nofollow">Paramiko</a> as following to run a <strong>command in background</strong> on server:</p>
  
  <pre><code>client.exec_command('test &gt; /dev/null 2 &gt; &amp;1 &amp;')
  </code></pre>
  
  <p>But I can't see the process by '<code>ps aux | grep test</code>'.</p>
  
  <p>Why can this be?</p>
