With access to the kernel sources, you doesn’t have to remember what
the others do, see
‘/usr/src/linux/Documentation/admin-guide/sysrq.rst’.
This file doesn't exist on my system (not even the directory
"admin-guide").
I can find it under:
/usr/src/linux/Documentation/sysrq.txt
That’s interesting, I doesn’t expect that. Maybe we are using different
kernel sources. Mine is ‘sys-kernel/gentoo-sources-4.10.12::gentoo’ but
wait, I’ve found it also under ‘Documentation/sysrq.txt’ with version
4.9.16 and it’s slightly a little bit different (in form not in content
as far as I can see).
But in my case I even had no access to any file, because no command
was working anymore. So I think it is better to have these information
on a good old sheet of paper. ;-)
Ha, yes of course, a paper backup beats them all (under typical
circumstances). ;-)
