Clears before displaying. Redraws the screen instead
of scrolling for faster displays. This option is
ignored if the terminal does not have the ability to
clear to the end of a line.

each screenful, rather than the default (the
number of lines in the terminal screen less
% man less
-c or –clear-screen
Causes full screen repaints to be painted from the top
line down. By default, full screen repaints are done
by scrolling from the bottom of the screen.
-C or –CLEAR-SCREEN
The -C option is like -c, but the screen is cleared
before it is repainted.
-[z]n or –window=n
Changes the default scrolling window size to n lines.
The default is one screenful. The z and w commands can
also be used to change the window size. The “z” may be
omitted for compatibility with more. If the number n is
negative, it indicates n lines less than the current
screen size. For example, if the screen is 24 lines,
-z-4 sets the scrolling window to 20 lines. If the
screen is resized to 40 lines, the scrolling window
automatically changes to 36 lines.
