SETLEDS(1) General Commands Manual SETLEDS(1)
setleds - set the keyboard leds
setleds [-v] [-L] [-D] [-F] [{+|-}num] [{+|-}caps] [{+|-}scroll]
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
-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.)
In keyboard application mode the NumLock key does not influence the
NumLock flag setting.
