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

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.

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 volumes.

furthermore, the - in "-vf" denotes a group of short arguments, each short argument one character and therefore the group being of v short for volumes and f short for force(=true).

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