[kwlug-disc] Can You Write A Web Server in PURE BASH?! (no socat, no netcat, no external tools)

[Ronald Barnes]

I figure some folks on this list would enjoy Dave's bash videos. He's 
got a real expert level of knowledge and make it fun to learn obscure 
bash tricks.


Here, he builds a web server... in pure bash:

Although the thought of this challenge is mildly nauseous, the video is 
mesmerizing!


He builds a web server in pure bash, just like he promised. Even 
enhanced it by cloning and modifying the `accept` builtin to support 
keep-alive.

Here's his bash web server in action - amazing output:

curl ysap.sh


It's also amazing in a web browser with JS. I made something similar 
years ago (a terminal in JS) but not as nicely as https://ysap.sh




Also, he highly recommends "pure bash bible":
