Erase all lines but one using Ansible












-1















So I'm working with an Ansible playbook and my idea is to remove all lines from a debug variable but keep one. For example,



- name: Debug
debug:
var: json_response


Let's consider that json_response has 100+ lines. I would like to find my specific word and keep the line. Like this:



Keeping the line where you find the words: "crazy"



output.json:




I'm doing this test



So you guys can understand



What I'm saying



I'm a crazy test




And the result output.json would be:




I'm a crazy test




Right now, I've looked at the "lineinfile" module for ansible and it says:
"This module ensures a particular line is in a file, or replace an existing line using a back-referenced regular expression"



But it doesn't seems to fullfill my needs, any ideas?



Thanks

If json_response is a proper json data, you can use the json_query filter to search for the keyword: https://docs.ansible.com/ansible/2.7/user_guide/playbooks_filters.html#json-query-filter



Else, if it's a plain multi-line string, you can use regex_search filter instead: https://docs.ansible.com/ansible/2.7/user_guide/playbooks_filters.html#regular-expression-filters
