When you say Hack my grub, are you meaning edit the grub file? Cause I think that's not really hacking!!
s/hack/modify/ >revised\ comment;
Whoa, that's way over my head at the moment! I'm just gonna steer clear of that for a bit!
It's Linux nerd humor. sed is a Linux command that among other things substitutes text. For the command "s/hack/modify" it searches through the text for any instance of "hack" and replaces it with "modify".
To change that 8 seconds to something more reasonable, as root, edit the file /etc/default/grub and change the GRUB_TIMEOUT value, then run the command update-grub.
