Hello everybody and thanks always for the help

I think the question I am about to ask is very beginners like, so I would appreciate the help.

I know (although I don't remember right now) there is a way to run a program on boot. I think it involves rc.local (correct me if I am wrong) I think you can put there the processes that you want to be run everytime linux is rebooted.

My question is, what should I do if I want a program to be run everytime some other event happen? For example (and in concrete) I am using a camera connected to my linux system and I want a program to run everytime I unplug and replug the camera through the USB port.

Can someone share his/her knowledge with me on this point

Thanks a thousand

In udev using systems each plug/unplug of camera produces a kernel event and udev is notified and it takes whatever action it is configured to do.

So you have to configure udev rules in /lib/udev/rules.d or /etc/udev/rules.d appropriately. Rean man pages of udev.conf, udevadm.

Questions like this have been previously posted; search keywords 'udev.conf', 'rules.d', 'event'. Do a search of LQ.
