NAME
       clear - clear the terminal screen

SYNOPSIS
       clear

DESCRIPTION
       clear  clears  your screen if this is possible.  It looks in the environment for the terminal type and then in the terminfo database to figure out how to clear the screen.
       Some terminals can clear also their scrollback buffer to prevent access to potentially sensitive data.  If the terminfo entry for the terminal type contains extended capa‐
       bility E3, clear will use it to clear the scrollback buffer.

       clear ignores any command-line parameters that may be present.

SEE ALSO
       tput(1), terminfo(5)

       This describes ncurses version 5.9 (patch 20130511).
