Description:

Set the brightness of the LED. Most LEDs don't
|
|
have hardware brightness support so will just be turned on for
|
|
non-zero brightness settings. The value is between 0 and
|
|
/sys/class/leds/<led>/max_brightness.

Description:
|
|
Set the trigger for this LED. A trigger is a kernel based source
|
|
of led events.
|
|
You can change triggers in a similar manner to the way an IO
|
|
scheduler is chosen. Trigger specific parameters can appear in
|
|
/sys/class/leds/<led> once a given trigger is selected.
