alt Hacker NewsLinefeed (\n) is a single byte in DOS as well.
I think you are talking about carriage return linefeed pair (CRLF or \r\n),
These control codes go back to line printers. Linefeed advances the paper one line and carriage return moves the print head to the left.

Annoyingly I actually think '\r\n' is the correct line ending here - advance the paper and return the carriage, but I suppose unix took the simpler implementation which makes looping over characters, words (split by ' ') and lines (split by '\n') simpler as each loop only has a single comparison

In binary mode. In text mode if you printf(“Hello World\n”) you get CRLF because that’s how text works on DOS. Unix had the convention of only requiring the LF for text. And Unix didn’t have text/binary modes. That’s the compatibility hack on DOS.

Back to teletypes even. Believe me, I go back to line printers.
