title: Find files after a folder using regex on the Linux command line
body: <p>I have some folders like:</p>
  
  <pre><code>SRGRG-3DDD-E7DHC-VUDND4-8
  EHFAWFH-AWF8WF-WF74H4-G9799
  HDSRJ86-FJJ-SU8USH-DYYDCJ0
  </code></pre>
  
  <p>Inside them some files like:</p>
  
  <pre><code>file1
  file2
  file3
  </code></pre>
  
  <p>I am on a Linux environment. How can I use a <code>find</code> on the command line with a regex to find the file paths. So for <code>file1</code> I get this path <code>SRGRG-3DDD-E7DHC-VUDND4-8</code>
  And so on</p>
  
  <p>(I know the file names. Just need their paths)</p>
  
  <p>IT ISN'T A DUPLICATE. I NEED SOMETHING DIFFERENT, SPECIFIC TO WHAT I WANT</p>
