setterm - set terminal attributes
SYNOPSIS
setterm [options]
DESCRIPTION
setterm writes to standard output a character string that
will invoke the specified terminal capabilities. Where
possible terminfo is consulted to find the string to use.
Some options however (marked "virtual consoles only"
below) do not correspond to a terminfo(5) capability. In
this case, if the terminal type is "con" or "linux" the
string that invokes the specified capabilities on the PC
Minix virtual console driver is output. Options that are
not implemented by the terminal are ignored.
OPTIONS
For boolean options (on or off), the default is on.
For conciseness, an 8-color below is black, red, green,
yellow, blue, magenta, cyan, or white.
A 16-color is an 8-color, grey, or bright followed by red,
green, yellow, blue, magenta, cyan, or white.
The various color options may be set independently, at
least at virtual consoles, though the results of setting
multiple modes (for example, -underline and -half-bright)
are hardware-dependent.
-term terminal_name
Overrides the TERM environment variable.
-reset Displays the terminal reset string, which typically
resets the terminal to its power on state.
-initialize
Displays the terminal initialization string, which
typically sets the terminal's rendering options,
and other attributes to the default values.
-cursor [on|off]
Turns the terminal's cursor on or off.
-repeat [on|off] (virtual consoles only)
Turns keyboard repeat on or off.
-appcursorkeys [on|off] (virtual consoles only)
Sets Cursor Key Application Mode on or off. When
on, ESC O A, ESC O B, etc. will be sent for the
cursor keys instead of ESC [ A, ESC [ B, etc. See
the "vi and Cursor-Keys" section of the Text-Termi
nal-HOWTO for how this can cause problems for vi
-linewrap [on|off] (virtual consoles only)
Turns automatic line-wrapping on or off.
-default
Sets the terminal's rendering options to the
default values.
-foreground 8-color|default (virtual consoles only)
Sets the foreground text color.
-background 8-color|default (virtual consoles only)
Sets the background text color.
-ulcolor 16-color (virtual consoles only)
Sets the color for underlined characters.
-hbcolor 16-color (virtual consoles only)
Sets the color for half-bright characters.
-inversescreen [on|off] (virtual consoles only)
Inverts the screen colors. Foreground and back
ground are swapped, as are underline and half-
brightness.
-bold [on|off]
Turns bold (extra bright) mode on or off. Except
at a virtual console, -bold off turns off all
attributes (bold, half-brightness, blink, reverse).
-half-bright [on|off]
Turns dim (half-brightness) mode on or off (see
-hbcolor). Except at a virtual console, -half-
bright off turns off all attributes (bold, half-
brightness, blink, reverse).
-blink [on|off]
Turns blink mode on or off. Except at a virtual
console, -blink off turns off all attributes (bold,
half-brightness, blink, reverse).
-reverse [on|off]
Turns reverse video mode on or off. Except at a
virtual console, -reverse off turns off all
attributes (bold, half-brightness, blink, reverse).
-underline [on|off]
Turns underline mode on or off (see -ulcolor).
-store (virtual consoles only)
Stores the terminal's current rendering options as
the default values.
Clears the screen and "homes" the cursor, as
clear(1).
-clear rest
Clears from the current cursor position to the end
of the screen.
-tabs [tab1 tab2 tab3 ...] (virtual consoles only)
Sets tab stops at the given horizontal cursor posi
tions, in the range 1-160. Without arguments,
shows the current tab stop settings.
-clrtabs [tab1 tab2 tab3 ...] (virtual consoles only)
Clears tab stops from the given horizontal cursor
positions, in the range 1-160. Without arguments,
clears all tab stops.
-regtabs [1-160] (virtual consoles only)
Clears all tab stops, then sets a regular tab stop
pattern, with one tab every specified number of
positions. Without an argument, defaults to 8.
-blank [0-60] (virtual consoles only)
Sets the interval of inactivity, in minutes, after
which the screen will be automatically blanked
(using APM if available). Without an argument,
defaults to 0 (disable console blanking).
-dump [1-NR_CONS]
Writes a snapshot of the given virtual console
(with attributes) to the file specified in the
-file option, overwriting its contents; the default
is screen.dump. Without an argument, dumps the
current virtual console. Overrides -append.
-append [1-NR_CONS]
Like -dump, but appends to the snapshot file
instead of overwriting it. Only works if no -dump
options are given.
-file dumpfilename
Sets the snapshot file name for any -dump or
-append options on the same command line. If this
option is not present, the default is screen.dump
in the current directory.
-msg [on|off] (virtual consoles only)
Enables or disables the sending of kernel printk()
messages to the console.
-msglevel 1-8 (virtual consoles only)
Sets the console logging level for kernel printk()
messages. All messages strictly more important
has the same effect as -msg on and a logging level
of 8 will print all kernel messages. klogd(8) may
be a more convenient interface to the logging of
kernel messages.
-powersave on|vsync
Puts the monitor into VESA vsync suspend mode.
-powersave hsync
Puts the monitor into VESA hsync suspend mode.
-powersave powerdown
Puts the monitor into VESA powerdown mode.
-powersave [off]
Turns off monitor VESA powersaving features.
-powerdown [0-60]
Sets the VESA powerdown interval in minutes. With
out an argument, defaults to 0 (disable powerdown).
If the console is blanked or the monitor is in sus
pend mode, then the monitor will go into vsync sus
pend mode or powerdown mode respectively after this
period of time has elapsed.
-blength [0-2000]
Sets the bell duration in milliseconds. Without an
argument, defaults to 0.
-bfreq [freqnumber]
Sets the bell frequency in Hz. Without an argu
ment, defaults to 0.
