title: How to unescape a text file?
body: <p>I have a file <code>log.txt</code> with this content:</p>
  
  <pre><code>systemd[1]: Starting dracut cmdline hook...\r\n[    8.759274] systemd[1]:
  </code></pre>
  
  <p>When I do <code>cat log.txt</code> output is:</p>
  
  <pre><code>systemd[1]: Starting dracut cmdline hook...\r\n[    8.759274] systemd[1]:
  </code></pre>
  
  <p>Expected output is 2 lines (<code>\r\n</code> to be replaced with visibly new line):</p>
  
  <pre><code>systemd[1]: Starting dracut cmdline hook...
  [    8.759274] systemd[1]:
  </code></pre>
  
  <p>How to achieve this in a bash terminal?</p>
