How to not execute chef resource if directory is empty?

Question

I have a resource that looks as below:

execute 'run_command' do
  command "chown -R user:user * "
  not_if Dir["/home/user/dir1/*"].empty?
end

I want to make sure that the resource is not executed if /home/user/dir1 is empty

You won't really save all that much time; chown is pretty fast. Why does it matter? — Todd A. Jacobs
when the directory is empty, the command doesn't work and throws an error — meallhour

Try this:

not_if { Dir.entries("/home/user/dir1/").select {|entry| ::File.join("home","user","dir1",entry) and !(entry =='.' || entry == '..') }.empty? }
