title: Printing with sed or awk a line following a matching pattern
body: <p><strong>Question:</strong> I'd like to print a single line directly following a line that contains a matching pattern.</p>
  <p>My version of <code>sed</code> will not take the following syntax (it bombs out on <code>+1p</code>) which would seem like a simple solution:</p>
  <pre><code>sed -n '/ABC/,+1p' infile
  </code></pre>
  <p>I assume <code>awk</code> would be better to do multiline processing, but I am not sure how to do it.</p>
