Which module in Ansible should be used to edit file contents to replace a line?

To replace content in a file using Ansible, the replace module is typically used.

It allows searching for lines with a regex and replacing them with the desired text.

Example usage:

- name: Replace a line in a file
  replace:
    path: /path/to/file.txt
    regexp: 'old_text'
    replace: 'new_text'

If you just need to add or change a line, you can also consider the lineinfile module, but for replacement based on a pattern, replace is more suitable.
