title: Cat with new line
body: <p>My input file's contents are:</p>
  <blockquote>
  <p>welcome</p>
  <p>welcome1</p>
  <p>welcome2</p>
  </blockquote>
  <p>My script is:</p>
  <pre><code>for groupline in `cat file`
  do
          echo $groupline;
  done
  </code></pre>
  <p>I got the following output:</p>
  <pre>
  welcome
  welcome1
  welcome2 
  </pre>
  <p>Why doesn't it print the empty line?</p>
