Here is a slightly better version that prints the usage if a unknown option is given:
kay@pim:~/src/udev.kay$ ./udev -x
./udev: invalid option -- x
Usage: [-qrVh]
-q arg query database
-r print udev root
-V print udev version
-h print this help text
> Here is a patch that makes it possible to call udev with options on the command line.
> Valid options are for now:
>
> -V for the udev version:
> kay@pim:~/src/udev.kay$ ./udev -V
> udev, version 011_bk
>
> -r for the udev root:
> kay@pim:~/src/udev.kay$ ./udev -r
> /udev/
>
> -q to query the database with the sysfs path for the name of the node:
> kay@pim:~/src/udev.kay$ ./udev -q /class/video4linux/video0
> test/video/webcam0
