Grub Init Tune: Mario Bros. Mushroom Powerup

Grub Init Tune - Mario Bros. Mushroom Powerup

This Grub Init Tune will make your computer sound like a Super Mushroom every time you turn it on! This only works for the Grub bootloader - this generally means you need to have Linux (or other Grub-based OS) installed.

Here's the code, which goes in your /etc/default/grub file:

GRUB_INIT_TUNE="1750 523 1 392 1 523 1 659 1 784 1 1047 1 784 1 415 1 523 1 622 1 831 1 622 1 831 1 1046 1 1244 1 1661 1 1244 1 466 1 587 1 698 1 932 1 1195 1 1397 1 1865 1 1397 1"

Installation Instructions

Instructions adapted from https://web.archive.org/web/20150115050225/http://www.iavit.org/~john/debian/grub.html:

  1. Edit the file /etc/default/grub. At the end there are lines like the following:
    # Uncomment to get a beep at grub start
    # GRUB_INIT_TUNE="480 440 1"

  2. Replace the # GRUB_INIT_TUNE="480 440 1" line with the new GRUB_INIT_TUNE line at the top of this document (make sure to remove the "#" from the beginning of the line, as well). Save the file and exit your text editor. Open a terminal window and issue the following command: sudo update-grub

  3. Reboot. You should hear the init tune when the grub menu appears.

Here is a command ready to copy paste, (could be used in a post-install script): sudo sed -i 's/# GRUB_INIT_TUNE="480 440 1"/GRUB_INIT_TUNE="1750 523 1 392 1 523 1 659 1 784 1 1047 1 784 1 415 1 523 1 622 1 831 1 622 1 831 1 1046 1 1244 1 1661 1 1244 1 466 1 587 1 698 1 932 1 1195 1 1397 1 1865 1 1397 1"/g' /etc/default/grub && sudo update-grub
Note: some distros have #GRUB_INIT_TUNE (whithout space) instead of # GRUB_INIT_TUNE, in that case remove it from the command.

If GRUB_INIT_TUNE=" is for power up, What is the code for playing a sound when shutting down?

Grub is a bootloader. I am not sure that there is any equivalent as shutting down the computer won’t involve grub at all.

You should better search another way.

e.g running a script with systemd Before=shutdown.target
