udev rules

[jaypatel]

I am using udev rules to detect removable drives which executes a script having only this line:
notify-send "Drive detected".

#!/bin/bash
notify-send "Drive detected"

1.My udev rules are perfect.Had them checked
2.Script is getting executed.Tested it by using touch /tmp/test command in the script.
3.The script works fine when run manually.
What is the problem?

You don't say what the problem is, but I guess notify-send does something useful when you run the script by hand, and this doesn't happen when it's executed by udev.

What is notify-send? Is there some difference in the environment of the two different executions, like the DISPLAY variable or something?

Try sending the notifications to an active display. Scripts run by udev and cron and root don't inherit your user's $DISPLAY environment variable.

DISPLAY=:0.0 notify-send "Drive detected"
