title: Can't remove a directory in Unix
body: <p>I've got a seemingly un-deletable directory in Unix that contains some hidden files with names that start with <code>.panfs</code>.  I'm unable to delete it using either of these commands:</p>
  
  <pre><code>rm -R &lt;dir&gt;
  rm -Rf &lt;dir&gt;
  </code></pre>
  
  <p>Does anyone have any suggestions?</p>
