title: Regex to grab full firstname and first letter of last name
body: <p>I have a list of users grabbed by the <code>Etc</code> Ruby library:</p>
  <blockquote>
  <p>Thomas_J_Perkins</p>
  <p>Jennifer_Scanner</p>
  <p>Amanda_K_Loso</p>
  <p>Aaron_Cole</p>
  <p>Mark_L_Lamb</p>
  </blockquote>
  <p>What I need to do is grab the full first name, skip the middle name (if given), and grab the first character of the last name. The output should look like this:</p>
  <blockquote>
  <p>Thomas P</p>
  <p>Jennifer S</p>
  <p>Amanda L</p>
  <p>Aaron C</p>
  <p>Mark L</p>
  </blockquote>
  <p>I'm not sure how to do this, I've tried grabbing all of the characters: <code>/\w+/</code> but that will grab everything.</p>
