Hi,
Not read everything but first thing is that if you have a pipe in a
command call.... you should use shell module instead... That should fix
your first issue.

Note that my awk command should say "print $1" to get the IP address.
I don't see a way to edit my original question here to make this change.

I'm trying to get the IP address of one of my remote hosts by
querying my controller machine's /etc/hosts file which happens to
contain the IP addresses of all the servers I build with Ansible.
My Ansible playbook looks like this:

hosts:all
gather_facts:yes
become:yes
pre_tasks:
-name:getfile server's IP address
command: "grep prod-fs1 /etc/hosts | awk '{print$0 }'"

delegate_to: localhost
- debug: var={{ fs_ip_addr }}

However, I'm getting this error which I don't know how to fix:

It appears that the error is caused by the pipe symbol which is
why I enclosed the entire command in double quotes. But the error
occurs even if I remove them.
I should add that I know I could use this method of getting the IP
address of my file server...
|
-name:getfile server's IP address
set_fact:
fs_ip_addr=hostvars[groups['fileservers'][0]]['ansible_eth0']['ipv4']['address']
|
However, this option isn't available to me since I have to call
the playbook with the "limit" argument which cause the variable to
not be available.

deploy-webservers.yml -I inventory -l webservers
