The outputs of the help and/or vbeinfo command of the GRUB 2 shell are massive. How can I scroll up the output? I've tried PageUp and Shift+PageUp, but nothing happened.

  • I don't know the "proper" way to do it, but if you launch the grub-shell within screen, you can use its scrollback feature to get at the overflowed lists.

  • @Xyon, what scrollback feature? do you mean the kernel parameter mentioned in this thread?

After googling, I still haven’t found a way to scroll up the output of the GRUB 2 shell. However, there's a way to pause output (like the behaviour of the more command) - the pager environment variable.

13.1.24 pager

If set to ‘1’, pause output after each screenful and wait for keyboard input. The default is not to pause output.

So, issue a set pager=1 command first in the GRUB 2 shell, and then the output will behave like more.

GRUB 2 shell: set pager=1, and the output will be paused after each screenful
