You can use system("clear") or system("cls") according to the terminal you are going to print.

• If you are using the Windows Command Prompt, use system("cls").
• If you are using a Mac or Linux system, just use system("clear").

Or you can use a better way. Check this example.

count = 0

until count == 10
  system("cls") || system("clear")
  print count
  count += 1
  sleep 1
end
