Docker command 'docker rm -vf $(docker ps -a -q)

Question

just a quick question as I am learning docker and doing labs: I have learnt that to run the same command for all/many docker containers that after the command you can use $(docker -a -q) I know -a is to call ALL containers in all states, but what does the -q mean?

Similarly, in the command: docker rm -vf $(docker -a -q) what does the -v mean?

Thank you in advance.

I found the answer to my question already. I'm sharing what I've learner about these letters on a stick below in the hope it will help you, too! — hakre, Jul 15 '21 at 21:41

but what does the -q mean?

the - in "-q" denotes a short argument and q is short for quiet.

Similarly, in the command: docker rm -vf $(docker -a -q) what does the -v mean?

again, the - in "-v" denotes a short argument and v is short for volumnes.

compare with the output of the man docker-rm command:
