From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

TUI: ~~Terminal~~ Text User Interface, something like htop in example. CLI: Command Line Interface, something like grep in example.
Edit: "Text" is probably the correct word, not "Terminal".
Isn't the T for "text"? (ie. "Text User Interface")
I mean, in the context of Unix systems it's most likely gonna be within a terminal emulator, but in theory you can have a TUI inside an SDL window rendering the text there (specially when they are ports from other systems where they might be using different character sets than whats available in terminals.. or if they want to force a specific font).
The only example that comes to my head right now is ZZT, but I believe there are many games on Steam that use a TUI rendered within their own program, not a terminal.
Text makes sense. I mostly read it as "Terminal" and do not know what the original meaning is with a certainty. Looking at Wikipedia, the source of truth, it's https://en.wikipedia.org/wiki/Text-based_user_interface . You probably right about it.
