opposite of more

-F or --quit-if-one-screen
       Causes less to automatically exit if the entire file can be displayed on the first screen.

-R or --RAW-CONTROL-CHARS
       Like -r, but only ANSI "color" escape sequences are output in "raw" form.  Unlike -r,  the  screen
       appearance  is maintained correctly in most cases.  ANSI "color" escape sequences are sequences of
       the form:

            ESC [ ... m

       where the "..." is zero or more color specification characters For the purpose of keeping track of
       screen  appearance,  ANSI color escape sequences are assumed to not move the cursor.  You can make
       less think that characters other than "m" can end ANSI  color  escape  sequences  by  setting  the
       environment  variable  LESSANSIENDCHARS  to  the  list  of characters which can end a color escape
       sequence.  And you can make less think that characters other than the  standard  ones  may  appear
       between  the  ESC  and  the  m by setting the environment variable LESSANSIMIDCHARS to the list of
       characters which can appear.

-X or --no-init
       Disables sending the termcap initialization and deinitialization strings to the terminal.  This is
       sometimes desirable if the deinitialization string does something unnecessary, like  clearing  the
       screen.
