A Simple Docker command does not work on Windows 10

Question

I want to remove all containers

docker rm -f $(docker ps -aq)

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

I'm getting the following message

unknown shorthand flag: 'a' in -a
See 'docker rm --help'.

Answer 1

Try this one:

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

Answer 2

$() is not Windows syntax. Would probably work on Linux and Mac but not on windows. Therefore it would be better to use docker only command - prune. So to remove all stopped containers you can do:

docker container prune
