looping through results and writing lines to a file

I'm trying to loop through a list of lines and write the lines to a file.

- command: "{{ item }}"
  with_items:
    - ls 
    - df -h
  register: files
- lineinfile:
    line: "{{ item.stdout }}"
    path: /home/ubuntu/log/list.log
    create: yes
  loop: "{{ files.results | flatten }}"
  loop_control:
     label: item.stdout

But I am seeing below error:

'PermissionError' object is not subscriptable

I modified code as per @toydarian suggestion and working fine. if I have multiple tasks, I have changed as follows:

- command: "{{ item }}"
  loop:
    - "ls" 
    - "df -h"
  register: files

- command: "{{ item }}"
  loop:
    - "ls -lrt" 
    - "du -h"
  register: files1      

- lineinfile:
    line: "{{ item.stdout }}"
    path: /home/ubuntu/log/list.log
    create: yes
  loop: 
    - "{{ files.results }}"
    - "{{ files1.results }}"
  delegate_to: localhost

I can see below error:

"The task includes an option with an undefined variable. The error was: 'list object' has no attribute"

You have a small error in your loop. You can loop over files.results and then use {{ item.stdout }} as line:

  - command: "{{ item }}"
    loop:
      - "ls" 
      - "df -h"
    register: files

  - command: "{{ item }}"
    loop:
      - "ls -lrt" 
      - "du -h"
    register: files1
  
  - lineinfile:
      line: "{{ item.stdout }}"
      path: /home/ubuntu/log/list.log
      create: yes
    loop: "{{ files.results + files1.results }}"

Check the documentation on registering variables with a loop.

Note:
Depending on what you want to do, you might want to consider using ansible modules (e.g. find) instead of running things in command or shell tasks.
