Re: awk and graphics

[Miriam English]

That's something I would not have thought of.
I'm not sure how I'd get it to display realtime graphics...

Hmmm... I guess I could keep rewriting a pbm file and copying it to
another which acts like a frame buffer and which is displayed in an html
page that refreshes every few seconds without a webserver.
Interesting idea. Thanks David.
