How to scroll in grub2 shell?

The outputs of the help and/or vbeinfo command of grub2 shell are massive. How to scroll up the output? I've tried PageUp、Shift+PageUp, but nothing happened.

massive output in grub2 shell, how to scroll?

Solution 1:

After googled, I still can't found a way to scroll up the output of grub2 shell. However, there's a way to pause output (like the behaviour of 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 set pager=1 command first in grub2 shell, then the output will behave like more.

grub2 shell - set pager=1, output will paused after each screenful
