противоположно большему (opposite of more)
COMPATIBILITY WITH MORE
If the environment variable LESS_IS_MORE is set to 1, or if the
program is invoked via a file link named "more", less behaves
(mostly) in conformance with the POSIX "more" command
specification. In this mode, less behaves differently in these
ways:
The -e option works differently. If the -e option is not set,
less behaves as if the -e option were set. If the -e option is
set, less behaves as if the -E option were set.
The -m option works differently. If the -m option is not set,
the medium prompt is used, and it is prefixed with the string
"--More--". If the -m option is set, the short prompt is used.
The -n option acts like the -z option. The normal behavior of
the -n option is unavailable in this mode.
The parameter to the -p option is taken to be a less command
rather than a search pattern.
The LESS environment variable is ignored, and the MORE
environment variable is used in its place.
