Ubuntu bash scripting with root commands

Question

I am trying to write a bash startup script in Ubuntu 9.04 that will remove the annoying system beep from my computer:

#/bin/bash

rmmod pcspkr #remove system beep; also doesnt work without root access

it keeps coming back when I start my computer back on, and I want to run a startup script to remove this annoyance. But I do not know how to run as root in bash scripting, does anyone know how to log on as root in bash scripting?

Answer 1

Add this to the end of /etc/modprobe.d/blacklist:

blacklist pcspkr

This will prevent the pc speaker module from being loaded when you start the computer.

Answer 2

Put this command into /etc/rc.local.

Answer 3

1. Try System ==> Preferences ==> Startup Applications; You might be able to put your command right there...
2. Check this post describing a /etc/init.d path for one more option
3. You could add it to the root cron job (but that will go better with a module check).

do not have a Ubuntu handy to try this now.
