title: List all files that start with an empty line
body: <p>Struggling to find the answer to this...I've got a website with a bunch of PHP files, and somewhere there is an empty line before the opening php tag </p>
  
  <p>So what I want to do is first try finding all files in a directory where the first line is an empty line. </p>
  
  <p>Bonus points for a command that lets me search all files in a directory where there are one or more empty lines before the opening php tag.. </p>
  
  <pre><code>&lt;?php
  </code></pre>
  
  <p>Looking for a bash command that can do this...</p>
  
  <p>Also, needs to recursively search all directories within that directory.</p>
  
  <p>On Linux.....Thanks!</p>
  
  <p>UPDATE:
  Tried the suggestion from the John1024's answer, and this a file with the code below is being listed in the results </p>
  
  <pre><code>&lt;?php
  
  /**
   * @file
   * Defines custom functionality for ...
   */
  </code></pre>
