prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  E202 (no leading zero for octal permission) False positive
  # Issue Type
  - Bug report
  
  # Ansible and Ansible Lint details
  
  - ansible-lint installation method: Ansible Galaxy use of ansible-lint
  
  # Desired Behaviour
  
  ansible-lint provides correct reason to following the lint
  
  # Actual Behaviour (Bug report only)
  
  Please give some details of what is actually happening.
  Include a [minimum complete verifiable example](http://stackoverflow.com/help/mcve)
  with:
  - playbook
  - output of running ansible-lint
  - if you're getting a stack trace, output of
    `ansible-playbook --syntax-check playbook`
  
  "Numeric file permissions without leading zero can behave in unexpected ways. See http://docs.ansible.com/ansible/file_module.html" - https://docs.ansible.com/ansible-lint/rules/default_rules.html
  
  ./galaxy/downloads/tmp2REDBx/tasks/main-tasks.yml:4: [E202] Octal file permissions must contain leading zero
  
  ```
  # Lets create the configuration first...
  # avoid locking ourself out.
  
  - name: Create firewalld config directories
    file:
      dest: "{{ item }}"
      state: directory
      mode: "750"
    with_items:
      - /etc/firewalld
      - /etc/firewalld/zones
    notify: firewalld__reload
  ```
  
  It is not correct that "750" is mis-interpreted. "750" is a string, and is correctly interpreted as the octal permission number `750` i.e. `rwxr-x---`.
  
  Personally I have been using the string "750", rather than remember that YAML supports octal numeric literals using a leading zero.
