ansible filter debug output I have the following output resulted from a shell command which is run on ansible on every host from my inventory:

                ]
            }
        ]
    }
}


The information I need to extract and display on screen is this (for every host):

"stdout_lines": [
    "smm1: SMM: 1.10 (TESM14F)",
    "smm1: PSOC: 0.7"


The previous command with the full output is registered as a variable using ansible register module:

- name: Get smm version
  shell: some command
  register: smm_output


Then I'm trying to display it using (which displays the full output):

- debug:
    msg: "{{ smm_output }}"


If I'm using msg: "{{ smm_output.results.stdout_lines }}" it returns error

I also tried with json_query filter but with no results

So how do I parse that output?
The registered variable smm_output is a dict object and you can correctly dive into it. But you cannot use smm_output.results.stdout_lines because smm_output.results is a list. You need to iterate over it or filter the first element of results. So, if you know its only one element in the list, you should use smm_output.results.0.stdout_lines.
