英文:
Using Stat module on multiple files and using a map
问题
- name: 使用 stat 模块检查多个文件并注册结果
- name: 检查 ST 是否成功停止
stat:
path: "{{ item }}"
loop:
- /var/run/sshd.pid
- /var/run/httpd.pid
- /var/run/db.pid
register: status_stopped
当这些文件未找到或 stat 显示它们不存在时，我想执行以下任务：
- name: 清空 Axway 临时目录
shell: rm -rf /var/tmp/*
when: not status_stopped.results|map(attribute='stat.exists.false')|bool
当文件存在时，步骤仍然执行。是否有更好的处理方式？
英文:
I am using the stat module to check for multiple files and register the result
- name: Check if ST was successfully stopped
stat:
path: "{{ item }}"
loop:
- /var/run/sshd.pid
- /var/run/httpd.pid
- /var/run/db.pid
register: status_stopped
When these files are not found or stat states they do not exist, I want to perform a task like so:
- name: Clear out Axway tmp directory
shell: rm -rf /var/tmp/*
when: not status_stopped.results|map(attribute='stat.exists.false')|bool
When the files exists, the step still executes. Is there a better way to handle this?

以下是翻译的内容：
作为对您问题的直接回答：
- name: 当所有文件都不存在时，假装执行某些操作
ansible.builtin.debug:
msg: "所有文件都不存在。我必须执行的操作"
when: not (status_stopped.results | map(attribute='stat.exists')) is all
参考链接: 测试列表值是否为真
进一步说：
- 使用
shell来删除文件是不好的实践。使用file模块 并设置state: absent。 - 通过在
/var/run中的文件存在来检查服务是否正在运行是不好的实践。应正确地在操作系统中注册您的服务，并如 @U880D 在评论中提到的，使用service_facts，service，systemd，sysvinit... 取决于您的环境和需求。
英文:
As a direct answer to your question:
- name: Pretend to do something when all files are absent
ansible.builtin.debug:
msg: "All files are absent. Doing what I have to do"
when: not (status_stopped.results | map(attribute='stat.exists')) is all
Reference: Testing if a list value is true
To go further:
- Removing files with
shellis a bad practice. Use thefilemodule withstate: absent - Checking a service is running by presence of a file in
/var/runis a bad practice. Register your services correctly in your OS and as already reported by @U880D in comments, useservice_facts,service,systemd,sysvinit... depending on your environment and requirement.
