Pass args to a custom vim command

Custom commands are easy in vim:

:command HelloWorld echo "hello world"
:HelloWorld
" outputs hello world

But what if I want to pass an arg to the command?

First you have to specify that you want args with the -narg flag. Then you need to have declare where the args would go with <q-args>.

:command! -narg=1 Say :echo "hello" <q-args>
:Say world
" outputs hello world
