examine that. Otherwise:

Hi All,
I am declaring an environment variables in a playbook as shown below:
--
---
- hosts: localhost
environment:
script_var1: hi
script_var2: there
tasks:
- name: List
shell: bash test.sh
--
I want to test the existence of the above environment variables in a
separate task.yml file. How do I test their existence ? What is the
syntax ?
