I have a vars.yml with a list of users:

`  
linux\_users:

- username: testuser1  
state: present

- username: testuser2  
state: present  
`

If I create them, then add a third:

`  
linux\_users:

- username: testuser1  
state: present

- username: testuser2  
state: present

- username: testuser3  
state: present  
`

how can I output the username of the third user only (the one that is created)? My task file is:

`

- hosts: 127.0.0.1  
become: True  
vars\_files:

- vars.yml

- name: Create user  
user:  
name: “{{ item.username }}”  
state: ‘{{ item.state }}’  
register: user  
with\_items: ‘{{ linux\_users }}’  
when: item.state != ‘absent’

- name: Output username  
debug:  
msg: “User was created: {{ item }}”  
with\_items: ‘{{ user.results[2].name }}’  
when: user.changed  
`

{{ user.results[2].name }} outputs what I need, but obviously I won’t know which user will be created, so this needs to be dynamic. Is there some way to register an index integer of the user in the list that was created?

this is probably what you want:

&nbsp;&nbsp;- name: Output username  
&nbsp;&nbsp;&nbsp;&nbsp;debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "User was created: {{ item.name }}"  
&nbsp;&nbsp;&nbsp;&nbsp;with\_items: '{{ user.results }}'  
&nbsp;&nbsp;&nbsp;&nbsp;when: item|changed
