title: Using Sed to search for a string in an HTML file
body: <p>I am going a simple sed search in an HTML file looking for the tag "title=":</p>
  
  <p><code>sed '/title=/ p' index.html</code></p>
  
  <p>I expect it to find that tag but sed prints the whole file.</p>
  
  <p>I am using macOS Sierra.</p>
