title: Linux- force remove a folder
body: <p>I am using the <code>sudo rm -rf &lt;foldername&gt;</code> to remove a folder, however it gives such output:</p>
  
  <pre><code>rm: cannot remove `thisfolder/initialize.sh': Permission denied
  </code></pre>
  
  <p>What's the issue here? Is there a way to force remove a folder?</p>
