Is there a specific term for "tone of command" in English?

I’m wondering if there is a specific word that refers to a "tone of command." I’m putting it in double quotations because in my native language (Korean) we have a specific word called "myung-nyung-jo" (for some reason the website won’t let me write Korean) which literally translates to "commanding tone" but I can’t think of anything in English.

I initially thought that it may be related to causative verbs, but that doesn’t seem accurate as well. For example:

1. Could you find my glasses for me?
2. Find my glasses for me.

The second sentence would be the type of sentence I’m interested in. Thanks.
