udev

When I use udev rules to execute a bash script it is executed more than once (7 times).Is there a way to stop it after the first time? I'm using ubuntu 7.10

Use the export command to export a flag, and abort execution if the flag exists. Something like this:

Code:

[ "$Script_run" = "yes" ] && exit 0
export Script_run=yes

Note that $Script_run should not be a standard shell variable that wuld be automatically set during the boot process.

The device i`m try is a USB Infra red adapter.If i use a flag as you have said udev won't run that script again unless i restart the computer.

Yes, but that's what your first question asked. You wanted it to "stop after the first time." So, can you be clearer about what you're asking?

By the way, you don't have to reboot. Just have another script:

Code:

#!/bin/bash
unset -v Script_run

Sorry for not being clear about my question.I did as you have instructed and now the script is run only once.Thank you.
