Anyone know of a mod to create custom terminal logs?

I've tried looking for a mod that just does exactly this, but it seems like there simply isn't one. Am I wrong? Does anyone know of anything like that? Or am I going to need to try to learn how to make it myself?

I just want to be able to add my own text logs to the terminal with custom commands to access them. Like, for example, you type "advice" into the terminal and it reads back "get scrap, don't die".
