2.3 The “/ex” Command¶
We used the
/ex command once, in Section 2.1. It seems
important, doesn’t it? If you expected me to say that it’s not important, you’re wrong.
/ex command will be a critical part of your Denizen experience. It can run scripts for you, let you test a
command or two, and possibly save you in a pinch (though we should probably avoid getting ourselves into sticky
situations anyways). It is one of the most powerful parts of our toolbox, so it is important that you understand what it
does and how to use it.
Simply put, it can run a Denizen command from in-game or via console. Does it sound underwhelming? Probably. However, it
is not to be underestimated. Permission to run the
/ex command should not be given to any user not trusted with
virtually full control over the server.
To give you a perspective as to how dangerous it can be in the wrong hands, consider the following command:
/ex execute as_server "op <player.name>"
This will run the command
/op PLAYER_USERNAME from the console, effectively granting the player who runs the command
operator status. For most servers, operator status is the position of full control over the whole server. This is
clearly not ideal if the player running the command is untrustworthy in any way.
Making operators powerless won’t help. As long as the player has access to the
/ex command, they can do anything
within the limitation of Denizen. As we mentioned in Section 1.1: Introduction, that limit can be higher than you can see. Hopefully this demonstrates the power
/ex command wields.
