"A no-installation version: `htop | nc seashells.io 1337`"

I'm confused ... you are running the command 'htop' locally (and piping it) so how is that not installed locally ?

Is htop a local, (n)curses based app that you run in a console or is it something else that I am missing ?

Perhaps he means a no installation way to show htop on a web-page?

Assuming you have 'htop' installed, you can pipe it's output to seashells.io via `nc` (netcat) and it will give you back a URL where you can see the output.

Indeed, anything can be piped in, i.e.

while true;do date;sleep 1; done | nc seashells.io 1337

FYI, you can make it shorter by using sleep in while's condition, no need for while true. It does delay the first output though.

while sleep 1; do date; done | ...

thanks for the tip, old habits die hard :)

Doesn't the difference lie in whether you want to run the command then sleep, or sleep first and then run the command?

Could also do `while date;do sleep 1;done`

Yes, I was on about the reason for the delay.

If you want short

while :...

that's clever, i've never thought of it, interesting considering how many while true;do ...;sleep X;done loops i've done

Yup, exactly!

You're not installing any additional software onto your machine (like a web server etc)
