[chef] Node or Role Attribute reference via Chef::Resource::Script::Bash

[David Chait < >]

All,
     I apologize if this is a rather basic question, but I cannot seem
to find a clear answer. I am trying to pull a node or role based
attribute into only_if or not_if logic within a Bash block, though so
far without a lot of luck. A> Is it possible? B> If so, how?

Thanks,
David
