Hi Luca,
Perfectly working what you have suggested.
I need one more suggestion, below is the content i want remove but when the
line ends with #name its not working ? do you know how to remove with that
also?
*Playbook:-*
cat resolve.yml
---
- hosts: TC2
become: yes
tasks:
- name: remove block regexps
blockinfile:
path: /tmp/resolv.conf
marker: "{mark}"
marker_begin: "nameserver 13.2.7.8 # dns1"
block: |
nameserver 13.2.7.9 # dns2
nameserver 13.2.7.10 # dns3
marker_end: "search eu.ro.net mrtools.ro.com mit.gbr.ro.com"
state: absent
backup: yes
*Client Side:-*
# cat resolv.conf
nameserver 13.2.7.8 # dns1
nameserver 13.2.7.9 # dns2
nameserver 13.2.7.10 # dns3
search eu.ro.net mrtools.ro.com mit.gbr.ro.com
Thanks,
Deepan M
