SETTERM(1)                 Linux Programmer’s Manual                SETTERM(1)




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  con-
       sulted  to  find the string to use.  Some options however (marked "vir-
       tual consoles only" below) do not correspond to a terminfo(5)  capabil-
       ity.  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, yel-
       low, 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-Terminal-HOWTO for how  this  can  cause  problems  for  vi
              users.

       -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  background  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-bright-
              ness, 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  con-
              sole,  -reverse off turns off all attributes (bold, half-bright-
              ness, blink, reverse).

       -underline [on|off]
              Turns underline mode on or off (see -ulcolor).

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

       -clear [all]
              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 positions, in the
              range 1-160.  Without arguments, shows the current tab stop set-
              tings.

       -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 argu-
              ment, 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 con-
              tents; 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 over-
              writing 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 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 mes-
              sages.

       -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.  Without  an  argu-
              ment,  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.

       -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 argument, defaults to
              0.
