[SETLEDS(1)](https://www.chedong.com/phpMan.php/man/SETLEDS/1/markdown)                             General Commands Manual                            [SETLEDS(1)](https://www.chedong.com/phpMan.php/man/SETLEDS/1/markdown)



## 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 mo‐
       ment 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  interpretation
              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 setting.)

       -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.
