Cleanup Script for Docker Images and Containers

docker-clean.sh

#!/bin/sh

echo -e "-- Removing exited containers --\n"
docker ps --all --quiet --filter="status=exited" | xargs --no-run-if-empty docker rm --volumes

echo -e "\n\n-- Removing untagged images --\n"
docker rmi --force $(docker images | awk '/^<none>/ { print $3 }')

echo -e "\n\n-- Removing volume directories --\n"
docker volume rm $(docker volume ls --quiet --filter="dangling=true")

echo -e "\n\nDone :)"

Is there a special reason why you use "xargs" in the first one and "$(...)" in the others ? Thank you 😅 I think I am missing something subtle.
