ansible:tldr:d4956

This command is an example of using Ansible to execute a command on a group of hosts specified by the variable ${group}.

Here's the breakdown of the command:

• ansible: This is the basic command to run Ansible.
• ${group}: This is a variable representing the group of hosts you want to target. You would replace ${group} with the actual group name, such as web_servers or database_servers.
• -m command: This specifies the Ansible module to use, in this case, the command module. The command module allows you to run arbitrary commands on the remote hosts.
• -a '${my_command}': This is the argument for the command module. It specifies the command you want to execute on the remote hosts and is passed as a variable ${my_command}. You would replace ${my_command} with the actual command you want to run, such as ls or apt-get update. The command should be enclosed in single quotes (') to preserve any special characters or variables within it.

So, when you run this command, Ansible will execute the specified command (${my_command}) on the hosts in the specified group (${group}).
