Topic: howto change brightness from CLI on Chumby 8

How can I change the display brightness on a Chumby 8 from the command line (without involving the control panel)?

I've changed the software of my Chumby 8 to start my own application in stead of the standard control panel. However I would like to have a little daemon in the background that dims the display if I haven't touched the screen the last x minutes.  On a Chumby classic this can be easily done through /proc/sys/sense1/brightness, however this interface doesn't exist on the Chumby 8.  How can I do this on a Chumby 8?

Thanks in advance,

Nico

On the C8 and I8, the brightness is done with "/sys/class/backlight/silvermoon-bl/brightness" as a percentage.
