adding rules in udev for my usb 8G to autorun rsync

jao_madn · 11-17-2011, 06:35 AM

Hi,

I would like to ask if someone knows and show/point me or simple help me how udev rules work in lucyd, upon my quest and search all the tuts i used is based on old udev since something i read the udev change in lucyd version.. I want to accomplised when i plug my usb 8Gb device and automount kicks in mounted the usb in /media/sony storage and predefined rsync script must run. Im having problems udev function works for me..

Here some of my available info

Quote:

# udevadm info -a -p /block/sdc

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Hope someone has valuable input they can share..

Thanks in advance..

IDK how udev works on Lucid (Ubuntu is often different) but AFAIK the best page about udev rules (although it is outdated) is still this one. The first of your rules looks valid. What evidence do you have that the script is not running? Have you tried simple debugging techniques like making the script create a file?
