This is just a small tip. A lot of us use CYGWIN as a port of *nix apps in windows to do various things. And we use different types of terminal like CMD on windows, Git-Bash or Konsole. Now the problem is, CYGWIN default (or even advanced) installation option doesn’t have ‘clear’ command like we have it in Linux. And it’s annoying esp. when we try a ls -l command and it fills up the screen. The undocumented feature of CYGWIN console is that it clears up the screen when you press CTRL+L.
So, use it when u need it
