How do I run 'Bash Script' by udev rule?

I found several questions on http://ift.tt/108OrcN & on http://ift.tt/gbk8l4 related to launch script by udev rules. But I can't find exact solution or certain answer for executing Bash script.

So, I'm asking the (canonical) question: How to run/launch/execute Bash script by means of udev rules?

Another thing that I found on Writing udev rules is:

udev does not run these programs on any active terminal, and it does not execute them under the context of a shell. Be sure to ensure your program is marked executable, if it is a shell script ensure it starts with an appropriate shebang (e.g. #!/bin/sh), and do not expect any standard output to appear on your terminal.

Hence, I want to know if possible that "How to run bash script by udev rules?"

Here is simple example of executing bash-script.

I've written 99-myrule.rules under /etc/udev/rules.d which contains:

ACTION=="add", ATTR{idVendor}=="0781", ATTR{idProduct}=="5567", RUN+="/home/pandya/example.sh"

I found Vendor & Product ID from lsusb output:

$ lsusb | grep SanDisk
Bus 001 Device 066: ID 0781:5567 SanDisk Corp. Cruzer Blade

And I want to execute experimental command zenity --info when my pendrive (of SanDisk listed above) attached.

so, I've writted /home/pandya/example.sh (which is called from RUN+= in udev rules) contians:

#!/bin/bash
zenity --info &
exit

But This script is not executing (in-spite of having execution permission). I've also tried following:

• export DISPLAY=:0 in script before zenity --info


• bash -c 'DISPLAY=:0 zenity --info

And of-course:

• sudo restart udev


• sudo udevadm control --reload-rules

But I can't get output zenity --info.

Hence How can I run Bash script by menas of udev rules? _{Suggest me if I'm missing anything.}
