NAME

       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.

       Below, an 8-color can be black, red, green, yellow, blue, magenta, cyan, or white.

       A 16-color can be an 8-color, or grey, or bright followed by red, green, yellow, blue,
       magenta, cyan, or white.

       The various color options may be set independently, at least on virtual consoles, though
       the results of setting multiple modes (for example, --underline and --half-bright) are
       hardware-dependent.

       The optional arguments require '=' (equals sign) and not space between the option and the
       argument. For example --option=argument.

       --appcursorkeys on|off
           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-Terminal-HOWTO for how this can cause problems for vi users.
           Virtual consoles only.

       --append console_number
           Like --dump, but appends to the snapshot file instead of overwriting it. Only works if
           no --dump options are given.

       --background 8-color|default
           Sets the background text color.

       --blank[=0-60|force|poke]
           Sets the interval of inactivity, in minutes, after which the screen will be
           automatically blanked (using APM if available). Without an argument, it gets the blank
           status (returns which vt was blanked, or zero for an unblanked vt). Virtual consoles
           only.

           The force argument keeps the screen blank even if a key is pressed.

           The poke argument unblanks the screen.

       --bfreq[=number]
           Sets the bell frequency in Hertz. Without an argument, it defaults to 0. Virtual
           consoles only.

       --blength[=0-2000]
           Sets the bell duration in milliseconds. Without an argument, it defaults to 0. Virtual
           consoles only.

       --blink on|off
           Turns blink mode on or off. Except on a virtual console, --blink off turns off all
           attributes (bold, half-brightness, blink, reverse).

       --bold on|off
           urns bold (extra bright) mode on or off. Except on a virtual console, --bold off turns
           off all attributes (bold, half-brightness, blink, reverse).

       --clear[=all|rest]
           Without an argument or with the argument all, the entire screen is cleared and the
           cursor is set to the home position, just like clear(1) does. With the argument rest,
           the screen is cleared from the current cursor position to the end.

       --clrtabs[=tab1 tab2 tab3 ...]
           Clears tab stops from the given horizontal cursor positions, in the range 1-160.
           Without arguments, it clears all tab stops. Virtual consoles only.

       --cursor on|off
           Turns the terminal’s cursor on or off.

       --default
           Sets the terminal’s rendering options to the default values.

       --dump[=console_number]
           Writes a snapshot of the virtual console with the given number to the file specified
           with the --file option, overwriting its contents; the default is screen.dump. Without
           an argument, it dumps the current virtual console. This overrides --append.

       --file filename
           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. A path name that exceeds the system maximum will be truncated, see PATH_MAX
           from linux/limits.h for the value.

       --foreground 8-color|default
           Sets the foreground text color.

       --half-bright on|off
           Turns dim (half-brightness) mode on or off. Except on a virtual console, --half-bright
           off turns off all attributes (bold, half-brightness, blink, reverse).

       --hbcolor [bright] 16-color
           Sets the color for half-bright characters.

       --initialize
           Displays the terminal initialization string, which typically sets the terminal’s
           rendering options, and other attributes to the default values.

       --inversescreen on|off
           Swaps foreground and background colors for the whole screen.

       --linewrap on|off
           Makes the terminal continue on a new line when a line is full.

       --msg on|off
           Enables or disables the sending of kernel printk() messages to the console. Virtual
           consoles only.

       --msglevel 0-8
           Sets the console logging level for kernel printk() messages. All messages strictly
           more important than this will be printed, so a logging level of 0 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.

           Virtual consoles only.

       --powerdown[=0-60]
           Sets the VESA powerdown interval in minutes. Without an argument, it defaults to 0
           (disable powerdown). If the console is blanked or the monitor is in suspend mode, then
           the monitor will go into vsync suspend mode or powerdown mode respectively after this
           period of time has elapsed.

       --powersave mode
           Valid values for mode are:

           vsync|on
               Puts the monitor into VESA vsync suspend mode.

           hsync
               Puts the monitor into VESA hsync suspend mode.

           powerdown
               Puts the monitor into VESA powerdown mode.

           off
               Turns monitor VESA powersaving features.

       --regtabs[=1-160]
           Clears all tab stops, then sets a regular tab stop pattern, with one tab every
           specified number of positions. Without an argument, it defaults to 8. Virtual consoles
           only.

       --repeat on|off
           Turns keyboard repeat on or off. Virtual consoles only.

       --reset
           Displays the terminal reset string, which typically resets the terminal to its
           power-on state.

       --resize
           Reset terminal size by assessing maximum row and column. This is useful when actual
           geometry and kernel terminal driver are not in sync. Most notable use case is with
           serial consoles, that do not use ioctl(3p) but just byte streams and breaks.

       --reverse on|off
           Turns reverse video mode on or off. Except on a virtual console, --reverse off turns
           off all attributes (bold, half-brightness, blink, reverse).

       --store
           Stores the terminal’s current rendering options (foreground and background colors) as
           the values to be used at reset-to-default. Virtual consoles only.

       --tabs[=tab1 tab2 tab3 ...]
           Sets tab stops at the given horizontal cursor positions, in the range 1-160. Without
           arguments, it shows the current tab stop settings.

       --term terminal_name
           Overrides the TERM environment variable.

       --ulcolor [bright] 16-color
           Sets the color for underlined characters. Virtual consoles only.

       --underline on|off
           Turns underline mode on or off.

       --version
           Displays version information and exits.

       --help
           Displays a help text and exits.

COMPATIBILITY

       Since version 2.25 setterm has support for long options with two hyphens, for example
       --help, beside the historical long options with a single hyphen, for example -help. In
       scripts it is better to use the backward-compatible single hyphen rather than the double
       hyphen. Currently there are no plans nor good reasons to discontinue single-hyphen
       compatibility.

BUGS

       Differences between the Minix and Linux versions are not documented.
