title: How to delete multiple folders in parallel?
body: <p>I have two directories on the same level and I can do:</p>
  
  <pre><code>rm -rf dir1/; rm -rf dir2/
  </code></pre>
  
  <p>but they will be running sequentially, how could I remove them in parallel? is there a generic solution too which allows me to extend to many folders?</p>
  
  <p><strong>Update</strong></p>
  
  <p>The directories may be deeply nested containing other directories and so on.</p>
