How to get the value of properties in the openfirmware?

[Ryan Wang]

Hi,

I know that we can use getprop to the get the value of some property.
I wonder can we run some command in the cmdline to do that? E.g,
if I want to get the value of bootargs, which command I can use?

I have tried printenv, but it didn't work for properties.

thanks,
