If you want to change some line in some file (for exampe it would be /etc/environment and line that beginning from JAVA_HOME ) on group of hosts with ansible you should use the next playbook:
---
- hosts: PCPool
sudo: yes
tasks:
- name: Change line
lineinfile: dest=/etc/environment regexp='^JAVA_HOME' line=JAVA_HOME="/usr/lib/jvm/java-8-oracle"
where hosts - group of hosts from ansible file hosts
ineinfile - module of ansible
and in console you should use the next command:
ansible-playbook change_line.yml -k --user=USER --ask-sudo-pass
if you want to chek the results:
ansible PCPool -u agent -k -m shell -a 'less /etc/invironment'
