Run a command on several hosts 🔗

The documentation Introduction to Ad Hoc commands is a great reference.

In the inventory file create the list of servers to target

[my_target_group_name]
host01.domain.ext
host02.domain.ext
host03.domain.ext

Run the command

ansible [target_group_name] -i path/to/inventory/file -m shell -a [your_command]

# Example
ansible my_target_group_name -i inventories/inventory -m shell -a 'df -h'

The module shell allows to run any shell command but one can use any module

If you need to become root to run the command pass --become to the ansible command.

Parameter	Description
`--become`	Become root
`-u <username>`	Change the username used
`--ask-become-pass` or `-K`	Prompts you for the password to use for privilege escalation
`-f 10`	Change how many machines are targeted simultaneously
