What's the default 14.04 /etc/default/grub file contents?
I, like this guy also accidentally whacked my /etc/default/grub file, though I did it by using > instead of >> in a configuration script. The provided answer looks different from what I remember in the 14.04 desktop default grub file...what does it contain?
Teaching to fish...is there some resource/method I could use to find the answer myself without having to do a 14.04 reinstall just to find out?
Solution 1:
There is still an answer possible to the part of the question "Teaching to fish...":
... could use to find the answer myself without having to do a 14.04 reinstall just to find out?
I did a search for /etc/default/grub on http://packages.ubuntu.com/#search_contents:
Sorry, your search gave no results
Stripped the first /etc, so the second source package name search is for /default/grub. The results give a hit:
/usr/share/grub/default/grubgrub2-common
Do I have this file still on my Ubuntu machine?
$ sudo ls /usr/share/grub/default/grub
/usr/share/grub/default/grub
or, for example:
$ sudo [ -f /usr/share/grub/default/grub ] && echo Found || echo Not\ found
Found
As a matter of fact, it is there.
And what are its contents?
$ sudo cat /usr/share/grub/default/grub

As you might have spotted there is one more obvious different line compared to the output from Rinzwind's answer:
#GRUB_HIDDEN_TIMEOUT=0
Solution 2:
Here you go:

# /boot/grub/grub.cfg.
