1x1.trans - Part #1 : Getting Started with Ansible Ad-Hoc Commands

This guide will help you to start your journey of Automation with Ansible. Here I am going to discuss Ansible Ad-Hoc Commands. In the previous articles, I talked about Ansible Inventories and how to configure with deferent environments like Local Infra with variable hosts and posts and also Public cloud managing with Dynamic inventory for AWS EC2.

In this article, I am going to talk about some useful commands which will help you to get started with ansible Ad-Hoc Commands to get hands-on practice with Ansible.1x1.trans - Part #1 : Getting Started with Ansible Ad-Hoc Commands

Ansible Ad-Hoc command is something that you might type in to do something really quick, but don’t want to save for later.

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.

Some useful tips to run Ansible Ad-Hoc commands.

call a shell command:

-a “$command”

call with sudo rights:


test if machine responses:

-m ping

call an arbitrary module:

-m $module -a “$argument”

gather specific facts:

Before executing the Ad-Hoc commands it is very important to know about Ansible Patterns that might help you to know where you’re going to run the Ansible-Hoc commands.

Patterns: You can use Ansible patterns to select the specific set of hosts/groups.

You can use the ansible help command to understand the Ad-Hoc command syntax and more.

Ansible Ad-Hoc Commands:

Suggestable Read: Check the list of all module

Run your first Ansible command on your Ansible server command line interface.

The below command will check the “uptime” in the group called “all”.


Explanation about the above command:

ansible: Ansible is the command to execute the Ad-Hoc Commands on the Shell environment.

all : This is a Group/hostname that you want to execute the commands.

-i : INVENTORY, –inventory-file=INVENTORY. specify inventory host path (default=/etc/ansible/hosts) or comma separated host list.

-m : Module name – That you want to execute on the remote servers. (default=command)

command : The Command module will execute the Commands on Remote Servers. It won’t support to do extra tasks like filtering the strings from command output. Check the Manual page ( [[email protected] ~]$ ansible-doc command ) for more info.

-a : MODULE_ARGS, –args=MODULE_ARGS-  module arguments.

“Uptime”: This is a Unix Command to get the server uptime details.
