I have a complex shell script that is run by ansible and I do want to communicate from it to ansible when changes were made on the system, so Ansible will know that the host was modified.
This is achieve by using changed_when: condition but the problem is that I cannot really rely on a specific exit code to be used for success_with_change instead of success_without_change.
What other options are available? Can I use register: and use the registered variable inside changed_when: in order to check for a placeholder string in the output?
