title: Linux 'find' only for current folder and specified ones
body: <p>I need to find files in the current folder (non-recursively) and some other folders (recursively). For example I have a tree structure like:</p>
  
  <ul>
  <li>folder1/</li>
  <li>folder2/
  
  <ul>
  <li>folder2-1/
  
  <ul>
  <li>file2-1.php</li>
  </ul></li>
  </ul></li>
  <li>folder3/
  
  <ul>
  <li>file3-1.php</li>
  </ul></li>
  <li>file1.php</li>
  <li>file2.php</li>
  </ul>
  
  <p>I want to find files <code>file1.php</code>, <code>file2.php</code> and <code>file2-1.php</code> only. So, search in the root + folder2/ recursively.</p>
  
  <p>All the resources I could find describe either </p>
  
  <pre><code>find . -maxdepth 1 -iname "*.php" // gives `file1.php` and `file2.php`
  </code></pre>
  
  <p>or</p>
  
  <pre><code>find folder2 -iname "*.php" // gives me `file2-1.php`
  </code></pre>
  
  <p>So:</p>
  
  <p><strong>Q.</strong> How do I combine these commands?</p>
  
  <p>P.S. I should be able to send the list of the found files further in the command line as well (for example to xgettext).</p>
