Ubuntu – Regenerate /etc/default/grub


I accidentally wiped /etc/default/grub with a mistyped :w !sudo tee %. Is there a way to regenerate its content? Is the original available somewhere to copy?

Surprisingly, that file /etc/default/grub/ doesn't seem to be provided by any package. I used dpkg -S /etc/default/grub, but it failed. However, you can copy the content of the default file from below. This file is same for Ubuntu 12.04 and 12.10.

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'
