Thanks for your response,
I have still issue when there are two elements matched in regex pattern.
please help
Playbook:
---
- name: list regex compare
hosts: localhost
gather_facts: no
connection: local
vars:
list1:
- linux.*
- 6.*
- mysql|python|gvim
list2:
- linux
- linux linux
- 6.0.2
- msql
tasks:
- debug:
msg: "{{ item.0 is match(item.1) }}"
loop: "{{ list2|zip(list1)|list }}"
- set_fact:
list3: "{{ list3|default([]) + [item.0 is match(item.1)] }}"
loop: "{{ list2|zip(list1)|list }}"
- debug:
msg: "{{ list3 is all }}"
output:
