Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a Symbol Microscan USB barcode scanner on a Fedora Core 4 system. It works much like a USB keyboard, and it uses the keybdev driver.
I would like to direct the output from this scanner to a specific program, even if there is a browser running or whatnot. If a user is looking at a webpage, and a barcode is scanned, I want to interrupt whatever is currently happening, process the barcode scanned and present the user with a webpage that displays information about the product scanned.
Any advice on how to do this? Hack the keybdev driver?
I have looked into JavaPOS in hopes that it might allow me to do this. The new version, however, only supports IBM products, and the one that was supposed to be written by Wincor Nixdorf in 2001 seems to be vaporware.
javapos.com is one of the least intuitive sites I have seen, many of the links don't work, and the new version of JavaPOS is IBM-only. Don't even ask about the docs on this site.
Ulitmately, JavaPOS is probbaly more than I want right now anyway, and I'm not even sure if it can do what I want it to.
So - any advice in trapping input from a specific USB keyboard (in this case a barcode scanner) and forcing it to pass it's output to a specific program/process regardless what else the system is doing?
