How compare two file in ansible

[Karther]

Hey,

I want compare two file in ansible.

Exemple :

I have one file : /home/ansible/repertory_1/file_1.txt

I have second file with the same file : /home/ansible/repertory_2/file_1.txt

I want that if my file file_1 who is in repertory_1 is the same content that my file (repertory_1) ansible does not do anything.

And if my file file_1 who is in repertory_1 is different content that my file file_1 in repertory_2 , ansible start apache.

Exemple for task who not works :

- name: "Copie du fichier dans test_d"

  copy:

      src: /home/ansible/repertory_1/file_1.txt

      dest: /home/ansible/repertory_2/file_1.txt

  delegate_to: localhost

- set_fact:

    myfile: "{{ lookup('file', '/home/ansible/repertory_1/file_1.txt') }}"

- name: "Start Apache"

  command: sudo systemctl start apache2

  when: myfile != /fome/ansible/repertory_2/file_1

I think that this tasks not works because myfile content "\n" at each line break

Someone have any idea please for my problem ?!!!

Thank you very much community ansible !!!! :)

You may want to use `stat` module. Get checksum of files and perform action based upon that - 

```

---
- hosts: localhost
  tasks:
    - stat:
        path: "./a"
      register: a_stat

    - stat:
        path: "./b"
      register: b_stat

    - debug:
        msg: "Files are same, perform something when they are same"
      when: a_stat.stat.checksum == b_stat.stat.checksum

```
