Explanation

The tput clear command is the portable way to clear the terminal screen in Unix/Linux systems. It uses the terminfo database to send the appropriate clear-screen sequence for whatever terminal type you're using. CLS is a Windows/DOS command and won't work in Unix shells, while CLEAR is not a standard command in any common shell.
