Terminal Command to disable Ambient Light Sensor?

[justn]

My end goal is to create a script that will disable and enable the Ambient Light sensor when I plug and unplug my MacBook Pro from power.

To do this I'm pretty sure I need a terminal command to enable and disable automatic dimming as the ambient light changes.

No, you can do it through System Preferences. I'm not at my Mac to check, but I believe it's in the Energy Savings section. Something auto-dimming.

Ah, it looks like it's in the Keyboard section actually.

I know how to do it in System Preferences, but as I said before I want a command I can use in Terminal to do it.

Disable it in System Preferences. Then in Terminal, enter:

defaults read com.apple.bezelservices

Enable it in System Preferences. In Terminal, enter:

defaults read com.apple.bezelservices

Compare to discover which key is involved. Once you know, you should be able to modify using defaults write

(I'm guessing that com.apple.bezelservices is the place to look.)

Actually you said,

which sounds like you wanted a command line way because you didn't know if it could be done via the GUI.
