clear - clear the terminal screen
clear
clear clears your screen if this is possible, including
its scrollback buffer (if the extended "E3" capability is
defined). clear looks in the environment for the terminal
type and then in the terminfo database to determine how to
clear the screen.
clear ignores any command-line parameters that may be
present.
