Hi all,

I have two task :

- name: “Utilisation du replace dans un fichier”  
set\_fact:  
mon\_fichier: “{{ lookup(‘file’, ‘/home/ansible/file.txt’) | replace(‘\n’, ’ ') }}”

and

- name: “Utilisation du regex\_replace dans un fichier”  
set\_fact:  
new\_file: “{{ lookup(‘file’, ‘/home/ansible/file.txt’) | regex\_replace(‘mon’,‘le’) }}”

The problem is that this both tasks do the same action.  
So what is a difference between the two module **replace** and **regex\_replace**?

Thanks for your help guy !! 😉

Regards,

I am only guessing here but I would assume ‘replace’ just doesn’t use regex syntax to accomplish the same goal.
