title: How to remove 3 blank lines in a row from file in Powershell
body: <p>Not sure if this is possible, but I'd like to use Powershell to accomplish the following: Remove the first 3 blank lines in any block of blank lines.</p>
  
  <p>For example:</p>
  
  <pre><code>hello
  
  this is a test
  
  
  
  
  this is still a test
  
  
  test
  </code></pre>
  
  <p>The expected output I'm looking for is:</p>
  
  <pre><code>hello
  
  this is a test
  
  this is still a test
  
  
  test
  </code></pre>
  
  <p>Is this possible?</p>
