docker --version

[Efficiently Delete Containers in Bulk]

docker stop db
docker ps -f status=exited -q
docker rm $(docker ps -f status=exited -q)
docker ps -a

[Step by Step Docker commands]

docker images
docker rmi [image_id or repository_tag]
docker ps
docker run --help
docker run -d ubuntu [no iteration]
docker ps -a
docker run -it ubuntu [with iteration]
docker ps -a
docker start peaceful-lehmann
docker exec -it peaceful-lehmann bash
   clear
   ps
   pwd
   ll
docker stop peaceful-lehmann

[Efficiently Delete Containers in Bulk]

docker ps -f status=exited -q
docker rm $(docker ps -f status=exited -q)
docker run -d --name j3-ubuntu ubuntu
docker run -d --rm --name j3-ubuntu ubuntu [If the container is finalized, it will be removed]

*******REMOVE CMDS******

[Applyed to all]

[If you want to forcefully remove images and containers, you can add the -f flag:]
-----------------------------------------------------------------------------------------------
[For containers:]

[To remove all stopped containers, use:]

docker rm -f $(docker ps -a -q)
-----------------------------------------------------------------------------------------------

[For images:]

docker rmi -f $(docker images -q)
-----------------------------------------------------------------------------------------------

[For Volumes]

docker volume rm $(docker volume ls -q)
-----------------------------------------------------------------------------------------------
[For Networks]


docker network rm $(docker network ls -q)

Note: These three networks cannot be removed:
Error response from daemon: bridge is a pre-defined network and cannot be removed
Error response from daemon: host is a pre-defined network and cannot be removed
Error response from daemon: none is a pre-defined network and cannot be removed
