Make :Q! have the same functionality as :q! in vim

Question

Sometimes in vim, I accidentally type :Q instead of :q in normal mode. To work around this, I've added this in my .vimrc:

command Q q

This works fine for :Q, but in case I type :Q!, vim responds with "No ! allowed". How do I make vim accept :Q! and interpret it as :q! ?

Answer 1

:command -bang Q quit<bang>
