The CLL is setting up a public access machine in the next coupleof weeks. It is installed with Mint 8 (a multimedia Ubuntu fork). I would like to set up a couple of init scripts. The first will delete the public account home directory and copy a "clean" version in its place each time the computer starts. The second will shut down the computer after half an hour of use.
I haven't touched on cron since university 20 years ago and I'venever written an init script. Having written a few shell scripts I know the copy script should be very simple. I'm not sure how to set up the timer script or make them run on start up. Would anybody be able to fire off some quick directions?
This may be a "foot in the door" situation. Later Mike

A simple addition to root's crontab should allow you to reboot the machine every 30 minutes without any problem. You could also give the user a warning message if you wanted to with notify-send .. see http://www.linuxjournal.com/content/tech-tip-get-notifications-your-scripts-... for reference.. or the september issue of LJ :)
I'll check out the link this afternoon. I like the idea of notification. Particularly if it's done through a pop-up dialogue box.
As to rebooting every 30 minutes, I was thinking about that earlier. I think it would be best to halt after 30 minutes of usage rather than every 30 minutes. Suppose someone starts up at say 1:29. They would only have one minute before shut down. If it was after 30 minutes of use they would have until 1:59.
All the best, Robert Keizer
