Hi@MD,

You can use lineinfile module in Ansible. This module has the capability to support regex expression. So you can create a regular expression and do your task as shown below.

- name: Replace a localhost entry with our own
  lineinfile:
    path: /etc/hosts
    regexp: '^127\.0\.0\.1'
    line: 127.0.0.1 localhost
