How to pass multiple special symbols with shell module?

I am using shell command to execute sed output piped to cut. Task in a playbook is as follow:

tasks:

  • name: “Task 1: Fetch inv”
    shell: ‘/bin/sed -n ‘/’{{ group }}’/,/^$/p’ {{ var_file }} | cut -d’=’ -s -f2’
    register: scriptout
  • debug: var=scriptout

I have tested manually from the command prompt, it is working fine. But when running in an Ansible gives following error:

ERROR! Syntax Error while loading YAML.

The error appears to have been in ‘/home/ansible/playbooks/my.yml’: line 15, column 31, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

#shell: ‘{{ linux_script }} {{ var_file }} {{ group }}’
shell: ‘/bin/sed -n ‘/’{{ group }}’/,/^$/p’ {{ var_file }} | cut -d’=’ -s -f2’
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:

with_items:

  • {{ foo }}

Should be written as:

with_items:

  • “{{ foo }}”

Please, someone can help me to understand the concept of escape characters should be used? Or pass the special characters as a string? and how to achieve the same?

{{ group }} and {{ var_file }} are variables.
