What are Ad-Hoc commands

Question

I've recently started studying Ansible. I had a small doubt. What are Ad-Hoc commands?

Answer 1

Ad-Hoc command is something that you would want it to be executed quickly without waiting for later. Ansible lets you do that without having to write an entire playbook for those commands.

Suppose you need to run a reboot for all your company servers in a group 'xyz' in 12 parellel forks, you can use the following Ad Hoc command:

$ Ansible xyz -a "/sbin/reboot" -f 12
