|
notes:
|
|
- Like all lookups this runs on the Ansible controller and is unaffected by other keywords, such as become,
|
|
so if you need to 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.
