title: Extract Nth line after matching pattern
body: <p>I want to extract the Nth line after a matching pattern using <code>grep</code>, <code>awk</code> or <code>sed</code>.</p>
  
  <p>For example I have this piece of text:</p>
  
  <pre><code>      Revision:
        60000&lt;br /&gt;
  </code></pre>
  
  <p>And I want to extract 60000.</p>
  
  <p>I tried <code>Revision:([a-z0-9]*)\s*([0-9]){5}</code> which matches the Revision together with the revision number but when I pass it to grep: <code>grep Revision:([a-z0-9]*)\s*([0-9]){5} file.html</code> I get nothing.</p>
  
  <p>How can I achieve this? </p>
