title: clear cache of browser by command line
body: <p>I am working in media domain. I need to check every change in all leading browsers i.e. IE, Firefox, Chrome, Safari and Opera.</p>
  
  <p>To clear cache, every time i need to use Ctrl + Shift + del.</p>
  
  <p>Is there any another way to clear the cache of every web browser using command line?</p>
