#not using stackexchange out of spite

[etoastie]

Sometimes I kinda wish it were more acceptable to ask lookup-able questions.

I just saw a CLI tool detect the height of my terminal and adjust its output to fit exactly in the terminal, and I wondered, "how does it know how big the terminal is"?

I thought this was a fun question, because it seemed on the boundary of something I probably could figure out on my own, but not very well. I kinda wanted to ask it to some folks, because it seems like a fun question. But I also just know that the answer is on stackexchange, you can probably find it with a search in less than 20 bytes. No point asking.

I kinda wanna try and find the answer without a search engine out of spite. Surely it exists in some docs that I have on-hand, or maybe a textbook. Sounds like a fun adventure.

But the answer's always there, beckoning one from that thorny, uncharted path to the well-paved road that's destroyed ecosystems and served generations.
