title: grep without showing path/file:line
body: <p>How do you grep and only return the matching line? i.e. The path/filename is omitted from the results.</p>
  
  <p>In this case I want to look in all .bar files in the current directory, searching for the term FOO</p>
  
  <pre><code>find . -name '*.bar' -exec grep -Hn FOO {} \;
  </code></pre>
