less is a program for paging through files or other output. It was written in reaction to the perceived primitiveness of more (hence its name). Some commands may be preceded by a number.
The lesskey command configures keybindings for less. See lesskey(1) for more information on it.
Set number of lines to scroll to num. Default is one screenful. A negative num sets the number to num lines less than the current number.
Run command on startup. If command is a number, jump to that line. The option ++ applies this command to each file in the command-line list.
Print help screen. Ignore all other options; do not page through file.
When searching, begin after last line displayed. (Default is to search from second line displayed.)
Use buffers buffers for each file (default is 10). Buffers are 1 KB in size.
Do not automatically allocate buffers for data read
from a pipe. If
-b specifies a number of
buffers, allocate that many. If necessary, allow information
from previous screens to be lost.
Redraw screen from top, not bottom.
Redraw screen by clearing it and then redrawing from top.
Suppress dumb-terminal error messages.
Automatically exit after reaching EOF twice.
Automatically exit after reaching EOF once.
Force opening ...
