title: How to fix bracket expansion when creating folders using a variable
body: <p>​
  I'm a novice user trying to do:</p>
  
  <pre><code>FoldersToCreate="folder1/subfolder,folder2,folder3,folder4"
  mkdir -p /mnt/user/public/test/{$FoldersToCreate}
  </code></pre>
  
  <p>which ends up making these folders:</p>
  
  <ul>
  <li><p>{folder1</p>
  
  <p>            - subfolder,folder2,folder3,folder4} </p></li>
  </ul>
  
  <p>I've read up and learnt about bracket expansion, but I can't find a solution to my problem.  Help please.  </p>
  
  <p>Thanks in advance.​</p>
