Validate setting is removed from a configuration

[Eric Marquez]

I'm working with some Dell OS 9 switches. I'm attempting to remove a command from the configuration. That part works. The part I'm having problems with is validating it was indeed removed from the configuration.

How do I do a validation check to ensure and command does not exist or is not contained in a result.

For example, I am removing the line from the configuration: "neighbor MUX_IPV4Clst[1-20] distribute-list external-prefix out", but there are multiple group names that will match and all are being removed.

- name: show running bgp
dellos9_command:
provider: "{{ cli }}"
commands:
- "do show run bgp | grep MUX_IPV4Clst3 | grep distribute"
# wait_for:
# - result.stdout ne 'distribute-list'
register: output

- name: debug
debug: var=output

- name: check bgp
shell: "echo {{ output.stdout_lines[0] }}"
# when:
# - output != "distribute-list"
when: output.stdout.find('distribute-list') != -1
