Ansible is a great tool for configuring servers. I only recently discovered the Ansible diff argument which can be used to check what changes are going to be made for a file. If you use this with the –check flag you can see what changes will be applied. I find this especially useful when coming back to a project after a break.
ansible-playbook paybook.yml –check –diff –limit my.example.com
