Hi,

While using set\_facts , I am combining a hostname and dns name .  
myhost = linuxhost1  
mydns = [example.com](http://example.com).

while combining them with set\_fact

ansible.builtin.set\_fact:  
my\_fqdn: “{{myhost}}.{{mydns}}”

This gives the desired output of “[linuxhost1.example.com](http://linuxhost1.example.com).”  
The last dot can be cut with [:-1] with debug , however I want to set this in set\_fact itself as I am trying to write the FQDN without a dot to the inventory file.

This should do the trick:

“{{myhost}}.{{mydns | trim(‘.’)}}”

Hi all,  
Where can I see the available options like

> trim(‘.’) which i can use in playbook.

Warm Regards,
