Mapping a command to a button

DebianUser · 10-27-2010, 12:28 AM

I have a headless server and i'd like to add a physical button that when pressed would execute a specific command, is there such a device?

Short answer: Sure

Longer answer: exactly how is this "physical button" going to be connected to your system? That will determine how to perform I/O with it.

RS-232 has always been a Pop Favorite. USB might also be a good choice. There are lots of other alternatives, too.

PS:
Q: How do you think a mouse button works? Or a joystick?

Have a look at D-Bus, too:
