title: cygwin clearscreen from bash
body: <p>I want to clearscreen from bash in a cygwin terminal.
  I have tried</p>
  
  <pre><code>cmd /c cls
  echo -e "^V^L"
  echo -e "\014"
  </code></pre>
  
  <p>None of these work - they all give a "linefeed". Pressing CTRL+L does work - but I want to call it from a Bash script.</p>
  
  <p>Any ideas?</p>
