Handlers
在 Ansible 中，你可以根據狀態是否變化，來觸發一些額外的操作。

ansible.builtin.lineinfile:
dest: "/tmp/example.txt"
line: "Hi from Ansible!"
check_mode: true # 根據檔案是否有 Hi from Ansible! 字串回傳 changed 屬性（沒有的話回傳 true）
notify: # 如果 changed 屬性為 true 則依序執行下面兩個操作
- Second command to run
- Third command to run
handlers:
- name: Second command to run
