Valid changes to list items

Question

I have a list of files. I want to iterate over a list of files retrieving only the path to a new list variable.

This gives me a list of files:

- name: sweep directory /foo/bar recursivly 
find:
  paths: /foo/bar
  recurse: yes
  patterns: "*"
  hidden: True
register: sweep_result

- name: build file list
set_fact: 
 all_list: "{{ sweep_result.files | map(attribute='path') | list }}"

- debug: var=all_list

Conclusion:

TASK [debug] *************************************************
ok: [host] => {
    "all_list": [
        "/foo/bar/.hiddenfile", 
        "/foo/bar/file1", 
        "/foo/bar/folder/file1", 
        "/foo/bar/folder/file2.ext",  
    ]
}

This is an example of what I want:

    "paths": [
        "/foo/bar/", 
        "/foo/bar/folder/",   
    ]

I see that iterating over all_list like this works on every element separating the file and extension, leaving me with only a path. I don’t know how to do something like this by creating a new list variable in the process.

- debug: var=item[:item.rfind('/')]
    with_items:
     - "{{ all_list }}"

Iterating over a list can give me duplicate paths. Using a “unique” filter can solve this. I am sure there is the right jinja style filter to get the result. Thanks for any help.

Answer 2

, file_type: directory ?

- name: sweep directory /tmp recursivly
      find:
        paths: /tmp
        recurse: yes
        patterns: "*"
        hidden: True
        file_type: directory
      register: sweep_result
