This command tells Docker to remove all containers that are not labeled with a maintainer of " jeremy." The != command is a logical notation that means " not equal to." To do so, use the command: docker container prune -filter="label!=maintainer=Jeremy" You can also specify to delete all objects that do not match a specified label. af indicates this should apply to all containers ( a) without a required confirmation ( f). The & attribute instructs Docker to remove all stopped containers and volumes. Then, the information is passed back to the container stop command and stops all the containers. Inside the parentheses, you instruct Docker to generate a list of all the containers with their numeric ID. This instructs Docker to stop the containers listed in the parentheses.
