This flag changes the operation of the module slightly; - insertbefore and insertafter will be ignored, and if the regexp - doesn't match anywhere in the file, the file will be left unchanged. - If the regexp does match, the last matching line will be replaced by - the expanded line parameter. - insertafter: - required: false - default: EOF - description: - - Used with C(state=present).
