仅当在已注册变量中找到字符串时，Ansible任务继续

我有下面的代码

- name: Try to delete file
  shell: rm -rf /tmp/"{{ file_Del }}"
  register: result
  ignore_errors: True 

- name: Display result
  debug:
    var: result.stdout

result.stdout可以是
“result.stderr”：“服务器错误（未找到）：未找到文件/tmp/somefile”

或
“result.stderr”：“

rm

不是很健谈。看见但是可以使用

find

和

xargs

。比如这出戏

- hosts: localhost
  vars:
    file_del: xxx
  tasks:
    - shell: "find /tmp/{{ file_del }} | xargs /bin/rm"
      ignore_errors: True 
      register: result
    - meta: end_play
      when: result.rc == 123
    - debug:
        msg: /tmp/{{ file_del }} found and deleted. Continue play.

给出（当找到并删除/tmp/{{file_del}}}时）

并在未找到文件

result.rc==123

时结束播放

---

注释

• 确保在未找到文件时报告rc 123
• 可以测试result.stderr

---

如果可能，编写一个自定义命令。比如说

$ cat my_custom_command.sh 
#!/bin/sh

if [ "$#" -eq "0" ]; then
   echo "[ERR 123] No files found.";
   exit 123;
fi

echo "Here I can do whatever I want with $@";
exit 0;

---

当你看这个问题的时候，看起来你的工作有点混乱，并且试图以这种方式继续下去。我认为最好不要朝这个方向走得更远，而是以更专业的方式工作

现在；更优雅的解决方案，仅使用Ansible模块

---
- hosts: local_test
  # gather_facts: False
  vars:
    file_Del: test
  tasks:
    - name: find some files at a location, recursively
      find:
        paths: "/tmp/{{ file_Del }}"
        recurse: true
      register: found_files

    - name: display files found, to be deleted, could be empty
      debug:
        msg: "Files found are {{ item.path }}"
      with_items:
        - "{{ found_files.files }}"

    - name: delete files when found
      file:
        path: "{{ item.path }}"
        state: absent
      with_items: "{{ found_files.files | default ([]) }}"

    - name: display files found, to be deleted, could be empty
      debug:
        msg: "{{ found_files }}"

    - name: end play when no files are found
      meta: end_play
      when: found_files.matched == 0

    - name: this task is skipped when there are no files found, but executed when files were deleted
      shell: echo hi

关于您的问题，请使用

“未找到rm-rf命令”

；这看起来很不寻常，例如，您同时在Linux和Windows主机上执行playbook，而任务在Windows主机上会失败。我知道的每台Linux主机都预装了

rm

，即使是大多数Docker容器和OpenBSD主机

将这些任务按环境分开可能是明智的

也许一点背景知识可以帮助我们，最终帮助你走出困境。

你只想在这里使用end_play，还是可以使用任何其他逻辑？你的“何时”状态对比赛结束不起作用吗？忽略错误不是很流行，不是吗？不能简单地在一个任务中找到文件，然后在下一个任务中，在找到文件时删除文件。不，不是。除非有充分的理由。例如，处理错误代码。@Kevin C:是什么阻止您发布自己的答案？实际的shell命令不是“rm”，而是我们的自定义命令。所以，这就是为什么我需要使用“find”来查找我在注册变量中拥有的内容，并在除了

“result.stderr”之外还有其他内容时终止Ansible:“来自服务器的错误（NotFound）：名称空间\“mynamespace \“NotFound”或result.stderr==”

，如果使用自定义命令，效果会更好。是什么阻止您在自定义命令中设置返回码？

$ cat my_custom_command.sh 
#!/bin/sh

if [ "$#" -eq "0" ]; then
   echo "[ERR 123] No files found.";
   exit 123;
fi

echo "Here I can do whatever I want with $@";
exit 0;
