This is a good place to start to understand the basics of what Ansible can do
prior to learning the playbooks language -- ad-hoc commands can also be used
to do quick things that you might not necessarily want to write a full playbook
for.
to do quick things that you might not necessarily want to write a full playbook for.
Generally speaking, the true power of Ansible lies in playbooks.
Why would you use ad-hoc tasks versus playbooks?

Use ``--ask-sudo-pass`` (``-K``) if you are not using passwordless
sudo. This will interactively prompt you for the password to use.

Rarely, some users have security rules where they constrain their sudo environment to running specific command paths only.
Rarely, some users have security rules where they constrain their sudo/pbrun/doas environment to running specific command paths only.
This does not work with ansible's no-bootstrapping philosophy and hundreds of different modules.
If doing this, use Ansible from a special account that does not have this constraint.
One way of doing this without sharing access to unauthorized users would be gating Ansible with :doc:`tower`, which
