I get syntax error due to the awk command as below.
ERROR! Syntax Error while loading YAML.

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:
Can you please suggest how can I incorporate such a awk in ansible
shell module ?
There are a few things you should know and consider:
From the shell command's documentation:
https://docs.ansible.com/ansible/latest/modules/shell_module.html
"If you want to execute a command securely and predictably, it may be
better to use the command
<https://docs.ansible.com/ansible/latest/modules/command_module.html#command-module>
module instead. Best practices when writing playbooks will follow the
trend of using command
<https://docs.ansible.com/ansible/latest/modules/command_module.html#command-module>
unless the |shell| module is explicitly required. When running ad-hoc
commands, use your best judgement."
So, consider using the command module.
From the command module's documentation:
https://docs.ansible.com/ansible/latest/modules/command_module.html
"The command(s) will not be processed through the shell, so variables
like |$HOME| and operations like |"<"|, |">"|, |"|"|, |";"| and |"&"|
will not work. Use the shell
<https://docs.ansible.com/ansible/latest/modules/shell_module.html#shell-module>
module if you need these features."
The pipe | won't work inline.
Also, your YAML has quoting issues. It becomes hard to quote long line
commands that has a mix of single and double quotes in YAML. You are
better off using the script module.
https://docs.ansible.com/ansible/latest/modules/script_module.html#script-module
Try the script module and see how it goes.
