SETLEDS(1)                           General Commands Manual                           SETLEDS(1)

NAME
       setleds - set the keyboard leds

SYNOPSIS
       setleds [-v] [-L] [-D] [-F] [{+|-}num] [{+|-}caps] [{+|-}scroll]

DESCRIPTION
       Setleds  reports  and  changes the led flag settings of a VT (namely NumLock, CapsLock and
       ScrollLock).  Without arguments, setleds prints the current settings.  With arguments,  it
       sets or clears the indicated flags (and leaves the others unchanged).  The settings before
       and after the change are reported if the -v flag is given.

       The led flag settings are specific for each VT (and  the  VT  corresponding  to  stdin  is
       used).

       By  default  (or with option -F), setleds will only change the VT flags (and their setting
       may be reflected by the keyboard leds).

       With option -D, setleds will change both the VT flags and their default settings (so  that
       a  subsequent reset will not undo the change).  This might be useful for people who always
       want to have numlock set.

       With option -L, setleds will not touch the VT flags, but only change the leds.  From  this
       moment  on, the leds will no longer reflect the VT flags (but display whatever is put into
       them).  The command setleds -L (without further arguments) will restore the  situation  in
       which the leds reflect the VT flags.

       One  might use setleds in /etc/rc to define the initial and default state of NumLock, e.g.
       by
            INITTY=/dev/tty[1-8]
            for tty in $INITTY; do
                 setleds -D +num < $tty
            done

OPTIONS
       -num +num
              Clear or set NumLock.  (At present, the NumLock setting influences the  interpreta‐
              tion of keypad keys.  Pressing the NumLock key complements the NumLock setting.)

       -caps +caps
              Clear or set CapsLock.  (At present, the CapsLock setting complements the Shift key
              when applied to letters.  Pressing the CapsLock key complements the  CapsLock  set‐
              ting.)

       -scroll +scroll
              Clear  or  set  ScrollLock.   (At  present,  pressing the ScrollLock key (or ^S/^Q)
              stops/starts console output.)

BUGS
       In keyboard application mode the NumLock key does not influence the NumLock flag setting.
