问题:

I am trying to find all '.vim*' files for a list of users in their home directory and remove them later on.

What I do:

vars:
  vim_users:
    - user1
    - user2

tasks:
- name: finding old vim configs in ~/ for all users
  find:
    file_type: any
    paths: ~/
    patterns: '.vim*'
    hidden: yes
  register: user_vim_config_files
  become: yes
  become_user: "{{ item }}"
  with_items: "{{ vim_users }}"

- debug:
    msg: "{{ item.files.path }}"
  with_items:
    - "{{ user_vim_config_files.results}}"

But getting Debug module failed:

TASK [debug] *******************************************************************************************************************************
fatal: [rpi]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined.
The error was: 'list object' has no attribute 'path'\n\nThe error appears to have been in '/Users/drew/CloudStation/rpi-scripts/minibian_start/ansible/test.yml': line 51, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - debug:\n      ^ here\n"}
to retry, use: --limit @/Users/drew/CloudStation/rpi-scripts/minibian_start/ansible/test.retry

Although if I remove ".path" ( path - this is what I need later for removing files with file module) and do the same but with:

...
- debug:
    msg: "{{ item.files }}"
  with_items:
    - "{{ user_vim_config_files.results}}"

Then I get this:

So as I understand I can access the {{ item.files }} and see the "path": "/home/user#/.vim" for all users in the list, but can not access item.files.path property. Why? How would you suggest to extract this information? Or maybe there is a better way to do it?

UPDATE

Tried:

- name: removing old vim configuration
  file: path="{{ item.files | map(attribute='path') | list }}" state=absent
  become: yes
  with_items: "{{ user_vim_confg_files.results }}"

Result: The files are still there and were not removed. Green output (instead of expected yellow changes)

My guess is that path now is a list of paths... so how would I organize some sort of nested loop in this case? Or am I wrong?

UPDATE

Tried to flatten as suggested:

- name: removing old vim configuration
  file:
    path: "{{ user_vim_config_files.results | sum(attribute='files', start=[]) | map(attribute='path') | list }}"
    state: absent
  become: yes

Result is green instead of expected yellow - none of matching files is removed. What can be wrong here?

回答1:

[ ] can not access item.files.path property. Why?

Because it does not exist. files is a list, so item.files[0].path, item.files[1].path etc. do exist, but there is no path key in item.files.

How would you suggest to extract this information?

For example:

{{ item.files | map(attribute='path') | list }}

Or maybe there is a better way to do it?

You can flatten the whole results-dictionary to get a list of paths in one fell swoop:

{{ user_vim_confg_files.results | sum(attribute='files', start=[]) | map(attribute='path') | list }}


回答2:

- name: Recursively find config.yml in /etc
  find:
    paths:  /etc
    patterns: 'config.yml'
    recurse: yes
  register: filelist


- name: use shell to print list of file paths
  shell: "echo {{ item }}"
  with_items: "{{ filelist.files|map(attribute='path')|list }}"

Posting the applied solution here:

vars:
  vim_users:
    - user1
    - user2

tasks:
- name: finding old vim configs in ~/ for all users
  find:
    file_type: any
    paths: ~/
    patterns: '.vim*'
    hidden: yes
  register: user_vim_config_files
  become: yes
  become_user: "{{ item }}"
  with_items: "{{ vim_users }}"

  - name: removing old vim configuration
    file:
      path: "{{ item }}"
      state: absent
    become: yes
    with_items:
      - "{{ user_vim_config_files.results | sum(attribute='files', start=[]) | map(attribute='path') | list }}"

I know it is kind of ugly solution, but at least it works... lol

Explanation:

"{{ user_vim_config_files.results | sum(attribute='files', start=[]) | map(attribute='path') | list }}"

returns the list of paths, extracted from user_vim_config_files.results

file module iterates over each path and removes all files.
