NAME
       clear - clear the terminal screen

       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.

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