Ansible register result of multiple commands

Question

I was given a task to verify some routing entries for all Linux server and here is how I did it using an Ansible playbook

---
  - hosts: Linux
    serial: 1

Starting in Ansible 1.6.1, the results registered with multiple items are stored in result.results as an array. So you can use result.results[0].stdout and so on.

Testing playbook:

---
- hosts: localhost
  gather_facts: no
  tasks:
    - command: "echo {{item}}"
      register: result
      with_items: [1, 2]
    - debug:
        var: result

Result:

$ ansible-playbook -i localhost, test.yml
