|
notes:
|
|
- Like all lookups, this runs on the Ansible controller and is unaffected by other keywords such as 'become'.
|
|
If you need to use different permissions, you must change the command or run Ansible as another user.
|
|
- Alternatively, you can use a shell/command task that runs against localhost and registers the result.
