ansible:tldr:4bfff

This command is using the Ansible automation tool to execute a command on a specified group of hosts.

Here's the breakdown of the command:

1. ansible ${group}: This part specifies the group of hosts on which the command will be executed. ${group} is a variable representing the name of the group.

2. --become: This flag enables privilege escalation, allowing the command to be executed with elevated privileges (typically using "sudo" or "su" commands).

3. --ask-become-pass: This flag prompts the user to enter the password for privilege escalation (become password) before executing the command. This is required since the command will run with escalated privileges.

4. -m command: This flag specifies the Ansible module to be used for executing the command. In this case, the "command" module is used, which allows running arbitrary commands on the remote hosts.

5. -a '${my_command}': This flag sets the arguments for the specified module. ${my_command} is a variable representing the command to be executed on the remote hosts enclosed in single quotes. The value of ${my_command} will be provided by the user when running this command.

Overall, this command runs the specified command (${my_command}) on the hosts belonging to the specified group, with privilege escalation and the user is prompted to provide the become password.
