I am trying to figure out how to generate a list of users on a remote machine who are currently already a member of group A , and append them all to group B  
Is this possible ?

Could not find a way to lookup existing users that are already a member of a group . I would like to be able to do this on different machines which have different users available , so creating a list of users on my ansible management station and using it as input is not an option

Please advice

Best Marc

You can retrieve members of a group using the `getent` module: [http://docs.ansible.com/ansible/getent\_module.html](http://docs.ansible.com/ansible/getent_module.html)

Such as:

- getent: database=group split=‘:’ key=sudo  
register: sudo\_users

- debug: var=sudo\_users.getent\_group.sudo[3]

The output should be a comma separated list. You could make this an actual python list using `sudo_users.getent_group.sudo[3].split(',')`
