如果任何文件存在，我需要将 hosts_example 或 hosts_Example 重命名为 hosts_real
- name: Playbook to Standardize Hosts
hosts: test
vars:
destpath: /etc/hosts_real
filename: [ /etc/hosts_example,/etc/hosts_Example ]
tasks:
- name: Check if file exists
stat:
path: "{{ item }}"
with_items:
- "{{ filename }}"
register: check_file_name
- debug:
msg: "{{check_file_name}}"
- name: Rename file
command: mv "{{ item }}"{{destpath}}"
with_items:
- "{{ check_file_name.results }}"
when: item.stat.exists == true
我尝试了这个，但出现了错误，无法达到预期的结果
这是错误

我修改了任务
- name: Rename file
shell: " mv {{ item }} {{destpath}} "
with_items:
- "{{ check_file_name.results }}"
when: item.stat.exists == true
我现在看到以下错误
["mv: target `/etc/hosts_real' is not a directory"]
答案1
您提供的参数太多了mv。item包含了很多信息，您只需要路径。请使用{{ item.stat.path }}。
这应该可以做到：
- name: Rename file
command: mv "{{ item.stat.path }}" "{{destpath}}"
with_items:
- "{{ check_file_name.results }}"
when: item.stat.exists == true
您也遗漏了"那一行。
另请注意，已with_items弃用，你应该将其改为循环。
