title: grep get matched text's filename and line number in bash
body: <p>I want to do a <code>grep</code> in bash on a folder searching for the term <code>foobar</code>. I then want to output all of the matches along w/ the <strong>filename</strong> and <strong>line number</strong> where the occurrences were found. Is this possible?</p>
  
  <p>I need the output to look like:</p>
