Overview

The module is mainly used to look for or change a single line in a text file. A typical use case is to ensure that a particular line is in a file, based on a regular expression. Another case is to replace an existing line using a back-referenced regular expression.

Module Parameters

line (value)

The line to be inserted.

insertafter

Used with state=present. The specified line will be inserted after the last match of the regular expression presented as value of insertafter, or, if the regular expression is not provided, after EOF.

TODO.

Example

- name: "Adjust Java version to {{ jdk.version }}"
  lineinfile:
    path: "{{ settings_path }}/settings.conf"
    regexp: '^JAVA_VERSION='
    line: "JAVA_VERSION={{ jdk.version }}"
