противоположно большему (opposite of more)
Описание (Description)
Less is a program similar to more(1), but which allows backward
movement in the file as well as forward movement. Also, less
does not have to read the entire input file before starting, so
with large input files it starts up faster than text editors like
vi(1). Less uses termcap (or terminfo on some systems), so it
can run on a variety of terminals. There is even limited support
for hardcopy terminals. (On a hardcopy terminal, lines which
should be printed at the top of the screen are prefixed with a
caret.)
Commands are based on both more and vi. Commands may be preceded
by a decimal number, called N in the descriptions below. The
number is used by some commands, as indicated.
