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.

A user types at a terminal (a physical teletype). This terminal is connected through a pair of wires to a UART (Universal Asynchronous Receiver and Transmitter) on the computer.

Once I had the opportunity to sit at such a machine.

A real typewriter with real paper. And no display! Only paper.

I type my "command line" and it appears on my paper. Ok, where else...

The computer responds by letting it's response appear - what do you think? - on my paper, too. Not by magic, but by my machine typing it.

I am typing to my paper. Then the computer is typing to my paper. And so on.

Hardly ever have I had such a creepy feeling while doing computer work 😵‍💫

I haven't used one as a tty, but my father had a typewriter like that.

He'd feed in forms for invoicing and software would have the typewriter fill in values in the right fields of that form.

I've had vt220/320/520 terminals back in the day. Been itching to source one now that I have a forever home to store crap like that, but they're becoming quite rare and expensive.
