Just to reiterate my requirement. I just want to create a remote
environment variable by assigning to it the value contained in a registered
variable while executing the shell command
as shown below....
---
- hosts: localhost
tasks:
- name: "subtask"
shell: lsblk --nodeps | grep disk | wc -l
register: disk_count_result
- name: "set fact"
environment:
MY_DISK_COUNT: "{{ disk_count_result.stdout }}"
