Hi Everyone,

Im trying to fetch output for yum check-update and export the output to a csv file for multiple hosts. but im unable to replace empty line with IP address of each server from inventory\_hostname (which is ip address) help would be greatly appreciated.

register: result

- debug:

msg: “{{ ansible\_distribution }}-{{ ansible\_distribution\_version }}”

- set\_fact:

# myvalue: “{{ result.stdout\_lines[0] }}”

# myvalue: “{{ result.stdout\_lines[0] | default([{{ ansible\_all\_ipv4\_addresses }}]) }}”

# myvalue: “{{ result.stdout\_lines[0] |regex\_replace(‘(0)’, ‘test’)}}”

myvalue: “{{ result.stdout\_lines[0] | regex\_replace(‘\n\*$’, ‘ansible\_hostname’) }}”  
vars:  
regexp: ‘^\s\*$’  
replace: ‘{{ inventory\_hostname }}’

- debug:
