The ansible ad-hoc command with the -a or --args option can be used to:

• Invoke a native Linux command on managed nodes
• Invoke a module on managed nodes

In this example, all managed nodes in your default hosts file or your own inventory file will be immediately restarted.

ansible all --args "/sbin/reboot now"

In this example, the yum module is used to update all managed nodes in your default hosts file or your own inventory file.

ansible all --module-name yum --args "name='*' state=latest"
