Переменные окружения (Environment variables)
Environment variables may be specified either in the system
environment as usual, or in a lesskey(1) file. If environment
variables are defined in more than one place, variables defined
in a local lesskey file take precedence over variables defined in
the system environment, which take precedence over variables
defined in the system-wide lesskey file.
COLUMNS
Sets the number of columns on the screen. Takes
precedence over the number of columns specified by the
TERM variable. (But if you have a windowing system which
supports TIOCGWINSZ or WIOCGETD, the window system's idea
of the screen size takes precedence over the LINES and
COLUMNS environment variables.)
EDITOR The name of the editor (used for the v command).
HOME Name of the user's home directory (used to find a lesskey
file on Unix and OS/2 systems).
HOMEDRIVE, HOMEPATH
Concatenation of the HOMEDRIVE and HOMEPATH environment
variables is the name of the user's home directory if the
HOME variable is not set (only in the Windows version).
INIT Name of the user's init directory (used to find a lesskey
file on OS/2 systems).
LANG Language for determining the character set.
LC_CTYPE
Language for determining the character set.
LESS Options which are passed to less automatically.
LESSANSIENDCHARS
Characters which may end an ANSI color escape sequence
(default "m").
LESSANSIMIDCHARS
Characters which may appear between the ESC character and
the end character in an ANSI color escape sequence
(default "0123456789:;[?!"'#%()*+ ".
LESSBINFMT
Format for displaying non-printable, non-control
characters.
LESSCHARDEF
Defines a character set.
LESSCHARSET
Selects a predefined character set.
LESSCLOSE
Command line to invoke the (optional) input-postprocessor.
LESSECHO
Name of the lessecho program (default "lessecho"). The
lessecho program is needed to expand metacharacters, such
as * and ?, in filenames on Unix systems.
LESSEDIT
Editor prototype string (used for the v command). See
discussion under PROMPTS.
LESSGLOBALTAGS
Name of the command used by the -t option to find global
tags. Normally should be set to "global" if your system
has the global(1) command. If not set, global tags are
not used.
LESSHISTFILE
Name of the history file used to remember search commands
and shell commands between invocations of less. If set to
"-" or "/dev/null", a history file is not used. The
default is "$XDG_DATA_HOME/lesshst" or "$HOME/.lesshst" on
Unix systems, "$HOME/_lesshst" on DOS and Windows systems,
or "$HOME/lesshst.ini" or "$INIT/lesshst.ini" on OS/2
systems.
LESSHISTSIZE
The maximum number of commands to save in the history
file. The default is 100.
LESSKEYIN
Name of the default lesskey source file.
LESSKEY
Name of the default lesskey binary file. (Not used if
"$LESSKEYIN" exists.)
LESSKEYIN_SYSTEM
Name of the default system-wide lesskey source file.
LESSKEY_SYSTEM
Name of the default system-wide lesskey binary file. (Not
used if "$LESSKEYIN_SYSTEM" exists.)
LESSMETACHARS
List of characters which are considered "metacharacters"
by the shell.
LESSMETAESCAPE
Prefix which less will add before each metacharacter in a
command sent to the shell. If LESSMETAESCAPE is an empty
string, commands containing metacharacters will not be
passed to the shell.
LESSOPEN
Command line to invoke the (optional) input-preprocessor.
LESSSECURE
Runs less in "secure" mode. See discussion under
SECURITY.
LESSSEPARATOR
String to be appended to a directory name in filename
completion.
LESSUTFBINFMT
Format for displaying non-printable Unicode code points.
LESS_IS_MORE
Emulate the more(1) command.
LINES Sets the number of lines on the screen. Takes precedence
over the number of lines specified by the TERM variable.
(But if you have a windowing system which supports
TIOCGWINSZ or WIOCGETD, the window system's idea of the
screen size takes precedence over the LINES and COLUMNS
environment variables.)
MORE Options which are passed to less automatically when
running in more compatible mode.
PATH User's search path (used to find a lesskey file on MS-DOS
and OS/2 systems).
SHELL The shell used to execute the ! command, as well as to
expand filenames.
TERM The type of terminal on which less is being run.
VISUAL The name of the editor (used for the v command).
