Using a Shell's STDOUT in a Chef ruby_block

recipe.rb

ruby_block 'shell out fun' do
  block do
    # this is me running my command and assigning the output to a var
    ls = shell_out('ls /var/')

    # this is me assigning the STDOUT to a var
    raw_output = ls.stdout

    # i used the Ruby p method to print out the raw chars
    # then i knew how to manipulate the string
    # in this case i am going to split the output by newlines and store it in an array
    clean_output = raw_output.split(/\n/)

    # here i am looping thru the array
    clean_output.each do |line|
      # setting the temp var you want to store this in and use later
      node.run_state[:output] = line

      # here i go notifying the resource i want to invoke knowing i have set
      # the temp variable i plan to use later
      resources(:execute => 'say_hello').run_action(:run)
    end
  end
end

execute 'say_hello' do
  # here i am going to lazy fetch the command value
  # so it will grab the latest value of the temp var we are using
  command lazy { "echo 'hello #{node.run_state[:output]}'" }

  # don't forget to make this do NOTHING until notified
  action :nothing
end
