Chef shell_out just giving hex values

I'm creating the Chef recipe below. However, my shell_out calls are just returning hex values for the expanded variable. How to get the value of the find command in the variable, and not a junk hex value?

Here is the relevant code snipet from my recipe::

so = nil

bash "getPath" do
Chef::Resource::RubyBlock.send(:include, Chef::Mixin::ShellOut)
command = "find \/ -path \\*ohai\/plugins"
so = shell_out(command)
end

listOfFiles = ["#{so}\cert.rb","#{so}\key.rb","#{so}\perms.rb","#{so}\propertiesFiles.rb","#{so}\warFiles.rb","#{so}\yum.rb"]
templates = { 1 => "cert.rb", 2 => "key.rb", 3 => "perms.rb", 4 => "propertiesFiles.rb", 5 => "warFiles.rb", 6 => "yum.rb" }
i = 1

listOfFiles.each do |remote|
template "#{remote}" do
source 'cert.rb' #this is going to be a variable once I figure out how to call it from the "templates" hash. Just doing a static file for troubleshooting purposes now
owner 'root'
group 'root'
mode '0644'
action :create
end
end


Here is part of the chef-client run output:

Answer

Almost there!

so = shell_out(command) # Returns a Mixlib::ShellOut object
output = so.stdout      # Returns stdout of your command, as String
