Ansible playbook 来检查操作系统

Question

如果系统安装了 Oracle Linux，我如何检查已安装的操作系统并继续下载文件。

这就是我要做的

- hosts: all
  become: true
  gather_facts: true
  tasks:
    - name: Check if oracle linux is installed
      shell: |
        cat: /etc/system-release
      register: os_name
      ignore_errors: yes
    - debug:
      msg: "{{os_name.stdout}}"```

Answer 1

- hosts: all
  become: yes
  gather_facts: true
  tasks:     

     - name: downloading file if Oracle Linux is there
       get_url:
              url: #url of the file to download 
              dest: #path where you want to store it eg. /etc/downloaded-file
              mode: '0600' #permissions to be given to the file
       when: ansible_facts['distribution'] == "OracleLinux"
