GRUB command line

[Niels Möller]

Hi,

I have a few minor suggestions for the command line interface and
the documentation thereof. Situation was this:

I boot, grub is started. When the menu is shown, I press c for the
command line. After typing a few commands, I realize why one of my
menu entries doesn't work. Now I want to get back to the manu, select a
different entry to boot into the operating system so I can correct my
error. But I couldn't easily find out how to do that; best I could
find was the reboot command.

It turneds out I could have used ESC to get back, but I didn't find
that at the time. It's mentioned in the message displayed wen entering
command line mode (but that information had scrolled away by the time
I needed it), but it's not mentioned in the message I get when typing
"help". It's also documented in the manual
(http://www.gnu.org/software/grub/manual/grub.html#Interface), but in
section 12.2 "The simple menu interface", not in section 12.1 "The
flexible command-line interface" which lists other key bindings. I'd
suggest:

1. Mention ESC in section 12.1 in the manual, with the rest of the key
   bindings.

2. Mention it in the help message displayed if I type "help" to the
   command line interface.

3. Define the "quit" command (currently available only or grub-shell)
   to do the same thing; exit the command line and return to the menu.

Also, when composing this message, I should tell you the version of
grub I'm using. According to grub-install --version after I've booted,
I'm using GNU Grub 0.97, but this is not necessarily the same version
as the one I have on the boot sector. And there's no version command
for the command line. So I'd also suggest

4. Add a "version" command to the command line interface. It should
   probably display version information for all the different stages,
   in case they for some reason are different.

Best regards,
