See full command of running/stopped container in Docker

docker ps --no-trunc will display the full command along with the other details of the running containers.

Use:

docker inspect -f "{{.Name}} {{.Config.Cmd}}" $(docker ps -a -q)

... it does a "docker inspect" for all containers.

Use:

docker inspect -f "{{.Path}} {{.Args}} ({{.Id}})" $(docker ps -a -q)

That will display the command path and arguments, similar to docker ps.
