title: Find all files that end with txt and out in all directories within a size margin
body: <p>Here is the code:</p>
  
  <pre><code>find /home/185053/ -iname "*.{txt,out}" -type f -size +8 -size -15
  </code></pre>
  
  <p>So, the command works if I exclude the <code>-iname "*.{txt,out}"</code> part out. </p>
  
  <p>I've tried using <code>| grep "*.{txt,out}"</code> at the end but that doesn't work either.</p>
  
  <p>Any ideas?</p>
