  <p>Desired output:</p>
  <pre><code>4444    pm      army    3687    anywhere    5650    infection
  7332    thesis  0638    nasa    3976    condition   0738    los
  3549    partners    fee 3930    move    6535    friends
  5693    matter  8801    visits  5350    grid    8917    honest

  </code></pre>
  <p>I am aware of two commands.</p>
  <blockquote>
  <p>awk '{print $3}' input.txt <br />
  sed '1~2d' input.txt</p>
  </blockquote>
  <p>But I am not sure how to combine them.</p>
  <p>Looking forward to any sort of help or suggestions.</p>
