"requires socat"

For tcp. There's another one which uses GAwk's internal tcp stack, but I wasn't sure if that would work in normal awk, and I'm a purist like that so you got this one.

I’d like to see both, please

Socat is a trivial stream converter, like a pipe fitting with different thread sizes on two ends.

The interesting part is the logic and the actual.string processing.

My first interesting question was, "How do I open a port in awk?!"

GNU Awk has an entire separate manual for TCP/IP internetworking: https://www.gnu.org/software/gawk/manual/gawkinet/

True, but you can go the other way and do it with only socat: socat -v tcp-listen:8888,reuseaddr,fork exec:'cat RESPONSE' is a (Very Static) entire web server, if RESPONSE has 2 header lines, a blank, and an html body. (A little too late in the morning for me to do the golfing needed to eliminate the "cat" and do the cr-nl from whatever shell you're already running, though.)

(scrolls down further in the socat manpage) Ohhh, under "EXAMPLES": you can combine a crlf option to TCP-LISTEN, SYSTEM instead of EXEC, and "echo -e", and there's actually a slightly useful http server already done :-)

Or cd to the html directory and run this:

  python -m http.server 8080

which does not require anything else like socat.

I think this is more of a “ain’t this interesting?” sort of thing.

Not a nawk on awk (pun intended) or socat, just a reply to the parent's comment.

This is functional and uninteresting.

For those who were drawn to ''awk'' in the title it is probably uninteresting. For those who were drawn to ''simple web server'', it is likely of some interest.

There are 1000 simple web servers. That part was never interesting to anyone interesting themselves.

If it had been "process some records with awk" that too would have been uninteresting even though it said awk.

"requires python"

Which in a way is somehow worse :P

in many ways

Yes, for some that would be a show-stopper. It is a nice one-line web service string, but should probably be run thusly:

  nohup python -m http.server 8080 2>/dev/null &

Nothing is interesting about overrated Python though

Ubiquitous, omnipresent, consistently rated in the top 2 or 3 most used computer languages. You don't like it, fine.

Apparently not fine. Are you about to cry?
