Hi Pixel_K. Thank you, nice work yourself. Ack on the rrdscript line, and I understand the versioning problem on the cut arguments. Sure, while loop is cleaner. Cron is cleaner too, actually. I just wanted to leave the shell attached to an xterm, so I could watch the data as it comes in. Having scratched my itch, I decided that was good enough. Want to use this thread like a version control system, with the latest code revisions in the most recent posts?

Ideally we could have the script act like an installer on the first run as well, asking the user what ip address the urad is on, where to store the data, etc. It could even test for curl and rrdtool on debian based derivatives (and likely others) and prompt an apt-get install of those if not present. I only say this because there will be a great many not so technical users, and we want to be able to collect data from their devices as well.
