[SOLVED]Catching Events

How do you catch certain events, both hardware and software?
For example I want to detect when my vga cable is unplugged or when mpd finishes playing a song.

I was playing around with handler.sh from acpid and I was hoping I could do the same for non-power related things.

Does this do what you want?

udevadm monitor

I'm not sure how I would use that.

I should have been more clear in my original post. I want to run a script when I plug in my VGA automatically.

Ah, I see. Do a search in {forums,wiki} for how to run a script on udev events. Within the last month, I can recall a few threads/posts about such things as:

switching power saving measures on when the power cord is unplugged, and turning power saving off when the cord is plugged in
switching to HDMI audio when the HDMI cable is plugged in, and reverting to the laptop speakers when the HDMI cable is unplugged

I trust you'll be able to suitably modify such information to suit your specific requirements ;-)

You can use 'watch' with some script that will query e.g. 'xrandr' to see if something's connected to VGA.
Some apps may have built-in features e.g. turn off the computer after it finishes playing the last song from the list.
