SETLEDS(1)                 General Commands Manual                SETLEDS(1)

NAME         top

       setleds - set the keyboard leds

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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         top

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