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.
...the command "s/hack/modify" it searches through the text for any instance of "hack" and replaces it with "modify".
Just the first one per line unless you s///g for global search and replace.
Nice, thank you.
If you want to learn shell commands you need to know about man and apropos
man is the manual for a command...
$man man to read the manual for the man command.
$apropos delete to search for commands containing the word "delete" in their descriptions.
