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 TASK [removeprefix : show running bgp] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* task path: /mnt/c/Users/emarq/Documents/Source/Repos/Solutions.Network.Automation/MAS/Ansible/dell/force10/roles/removeprefix/tasks/main.yml:27 Using module file /usr/lib/python2.7/dist-packages/ansible/modules/core/network/dellos9/dellos9\_command.py \<10.10.234.98\> ESTABLISH LOCAL CONNECTION FOR USER: emarq \<10.10.234.98\> EXEC /bin/sh -c '( umask 77 && mkdir -p "` echo $HOME/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531 `" && echo ansible-tmp-1479914628.77-259380380959531="` echo $HOME/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531 `" ) && sleep 0' \<10.10.234.98\> PUT /tmp/tmpgRL22M TO /home/emarq/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531/dellos9\_command.py \<10.10.234.98\> EXEC /bin/sh -c 'chmod u+x /home/emarq/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531/ /home/emarq/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531/dellos9\_command.py && sleep 0' \<10.10.234.98\> EXEC /bin/sh -c '/usr/bin/python /home/emarq/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531/dellos9\_command.py; rm -rf "/home/emarq/.ansible/tmp/ansible-tmp-1479914628.77-259380380959531/" \> /dev/null 2\>&1 && sleep 0' ok: [rr1-n22-r13-4048hl-5-1b] =\> {     "changed": false,     "invocation": {         "module\_args": {             "auth\_pass": null,             "authorize": false,             "commands": [                 "do show run bgp | grep MUX\_IPV4Clst3 | grep distribute"             ],             "host": "10.10.234.98",             "interval": 1,             "password": null,             "port": null,             "provider": {                 "host": "10.10.234.98",                 "ssh\_keyfile": "/srv/tftpboot/masd-rsa.pub",                 "transport": "cli",                 "username": "admin"             },             "retries": 10,             "ssh\_keyfile": "/srv/tftpboot/masd-rsa.pub",             "timeout": 10,             "transport": "cli",             "username": "admin",             "wait\_for": null         },         "module\_name": "dellos9\_command"     },     "stdout": [         "do show run bgp | grep MUX\_IPV4Clst3 | grep distribu\u001b[52D \u001b[55D$run bgp | grep MUX\_IPV4Clst3 | grep distribute\n neighbor MUX\_IPV4Clst3 distribute-list external-prefix out"     ],     "stdout\_lines": [         [             "do show run bgp | grep MUX\_IPV4Clst3 | grep distribu\u001b[52D \u001b[55D$run bgp | grep MUX\_IPV4Clst3 | grep distribute",             " neighbor MUX\_IPV4Clst3 distribute-list external-prefix out"         ]     ],     "warnings": } TASK [removeprefix : debug] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* task path: /mnt/c/Users/emarq/Documents/Source/Repos/Solutions.Network.Automation/MAS/Ansible/dell/force10/roles/removeprefix/tasks/main.yml:36 ok: [rr1-n22-r13-4048hl-5-1b] =\> {     "output": {         "changed": false,         "stdout": [             "do show run bgp | grep MUX\_IPV4Clst3 | grep distribu\u001b[52D \u001b[55D$run bgp | grep MUX\_IPV4Clst3 | grep distribute\n neighbor MUX\_IPV4Clst3 distribute-list external-prefix out"         ],         "stdout\_lines": [             [                 "do show run bgp | grep MUX\_IPV4Clst3 | grep distribu\u001b[52D \u001b[55D$run bgp | grep MUX\_IPV4Clst3 | grep distribute",                 " neighbor MUX\_IPV4Clst3 distribute-list external-prefix out"             ]         ],         "warnings":     } } TASK [removeprefix : check bgp] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* task path: /mnt/c/Users/emarq/Documents/Source/Repos/Solutions.Network.Automation/MAS/Ansible/dell/force10/roles/removeprefix/tasks/main.yml:39 fatal: [rr1-n22-r13-4048hl-5-1b]: FAILED! =\> {     "failed": true,     "msg": "The conditional check 'output.stdout.find('distribute-list') != -1' failed.
