[chef] RE: Re: Is there mechanism in Chef to capture return value of the command executed using "execute resource"?

Or if what you're looking for is a signal of when a resource successfully 
executes, you can use notifications:

Not like that, no. The question here is what exactly are you trying to
accomplish? Sometimes there are easier, more "chef" like ways to get
things done.

If you do need to do this, check out Mixlib::ShellOut
(https://github.com/opscode/mixlib-shellout) which will allow you to run a
command and look at the output.
