Name: clear Description: clear the screen Author: Jeffrey S. Haemer License:
clear - clear the screen
Look in the termcap database, find the character to clear the screen, and emit it.
This is a direct lift from Section 15.7, Ringing the Terminal Bell, from Perl Cookbook, with
Jeffrey S. Haemer
clear should probably take an argument,
that will let users send arbitrary termcap sequences,
cl as the default.
