Ad-hoc Commands

Ad-hoc is the concept of one-time Ansible commands.
You run a command on the inventory and a group, or even on specific hosts, to perform a one-time action.

Why Use Ad-hoc

These commands are useful for:

quick checks
one-time actions
tasks that do not need a full playbook flow yet

Example (From CLI)

ad-hoc

ansible OSPFrouters -i inventory.ini -m cisco.ios.ios_banner -a "banner=motd text='test' state=present"

One-shot banner push to the OSPFrouters group. No playbook.

Another quick operational example:

ad-hoc

ansible routers -i inventory.ini -m cisco.ios.ios_command -a 'commands=["show clock"]'

Run a show command on every host in routers.

Syntax Pattern

pattern

ansible  -i  -m  -a ''</code>
  Target, inventory, module, args. Same shape every time.
