title: How can I update values on the screen without clearing it in Perl?
body: <p>I want to display a set of values on screen and update that value every 5 seconds. I don't want to clear the screen. </p>
  
  <p>eg:</p>
  
  <p>hours: 1</p>
  
  <p>mins : 30</p>
  
  <p>sec: 45</p>
  
  <p>here, values should change accordingly.</p>
  
  <p>How should i do that in Perl?</p>
  
  <p>Regards,
  Anandan</p>
