Detailed explanation-2: -tput : Portable Terminal Control. The tput command allows shell scripts to do things like clear the screen, underline text, and center text no matter how wide the screen is. To do these things, it translates the terminal-independent name of a terminal capability into its actual value for the terminal type being used.
