Nice, thanks !

Some were the exact aliases I've been using for years on my own.

With two extras :

alias dcl='docker compose logs -f'

to display logs for a particular compose file.

and

function dupdate() {
	docker compose pull && docker compose build --no-cache
}

to update docker compose containers.

I don't get the use of aliases pointing to functions instead of giving the function the direct alias name ?
like so :

function drmid {
       imgs=$(docker images -q -f dangling=true)
       [ ! -z "$imgs" ] && docker rmi "$imgs" || echo "no dangling images."
}

and also why this kind of complicate things :

function dc-fn {
        docker compose $*
}
alias dc=dc-fn

instead of simply :

alias dc='docker compose'

There might be some reasons I don't get since I only use bash e.g. ?
