Get command usage help in docker

Question

If I vaguely remember the command and I’d like to confirm it, how will you get help on commands?

Answer 1

The following command is very useful as it gives you help on how to use a command, the syntax, etc.

$ docker --help

The above command lists all Docker commands. If you need help with one specific command, you can use the following syntax:

$ docker <command> --help
