Working in kernel debug land

This tip is valid for: Both BeOS and Haiku

Prior to BeOS 5, if something really serious happened that could halt the OS, all you would get would be a frozen desktop. In BeOS 5, critical errors will throw you into “Kernel Debug Land” — a sort of Terminal-like mode that will roll over the top of your desktop. Debug Land will let you enter specific commands in order to help Be’s tech support department troubleshoot problems.

Hopefully you’ll never see Kernel Debug Land (few users do), but if you do, and are trying to type commands, you’ll sometimes find that the output scrolls by too quickly to read (for example, the output of the “ps” command). To solve this, enter:

set paginate on
set pagesize 40

This will cause output to be displayed one screen at a time.
