How do you command someone to open the door in Spanish?

Here are a few ways to command someone to open the door in Spanish, with varying degrees of formality and urgency:

Formal:

* ¡Abra la puerta, por favor! (Open the door, please!) - This is the most polite and formal way to make the request.

* Le ruego que abra la puerta. (I beg you to open the door.) - This is even more formal and implies a sense of urgency or need.

Informal:

* ¡Abre la puerta! (Open the door!) - This is a direct and casual command.

* ¿Puedes abrir la puerta? (Can you open the door?) - This is a more polite and less demanding way to ask.

* Abre, por favor. (Open, please.) - This is a shorter and more informal way to say "open the door, please."

More casual:

* ¡Ábrela ya! (Open it now!) - This is a more demanding and impatient command.

The best way to say it will depend on your relationship with the person and the context of the situation.
