In Windows I have to use cls to clear the Console, in Linux just clear!

Is there a Function like:

system("cls") or system("clear")

Oh, it doesn't seem to have a good answer. Unless you want to install the `curses` gem, use [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code): `print "\e[H\e[2J"`. It's not as portable though. — cremno, Apr 03 '16 at 21:30

Nope, an already written method for both does not exists in ruby native libs. However, you can do something like that :

module OS
  def OS.windows?
    (/cygwin|mswin|mingw|bccwin|wince|emx/ =~ RUBY_PLATFORM) != nil
  end

  def OS.mac?
   (/darwin/ =~ RUBY_PLATFORM) != nil
  end

  def OS.unix?
    !OS.windows?
  end

  def OS.linux?
    OS.unix? and not OS.mac?
  end
end

then :

def clear_console
    if OS.windows?
      system("cls")
    else
      system("clear")
    end
end

credit goes to Aaron Hinni for the OS module.
