The command "ansible-inventory --list" is used to display the inventory data that Ansible uses in its operations. It retrieves and outputs the information about hosts and groups defined in the inventory files.

Here is a breakdown of the command:

• "ansible-inventory" is the command-line tool provided by Ansible to manage inventory.
• "--list" is an option that specifies the desired action to retrieve and display the inventory data in a JSON format.

When executed, this command will gather the inventory data from the default inventory file or any specified inventory file, and present it in a structured format. The information includes hosts and their associated attributes like IP addresses, port numbers, group membership, variables, and more.

By using the "--list" option, you can get an overview of the inventory setup, which can be helpful to verify the expected hosts, groups, and their configurations before running Ansible playbooks or commands.
