At Linux we can get run level as like:
if [ "$(runlevel | sed 's/.* //')" = 6 ]; then echo "A reboot is in progress" fi
and run level 0 is for shutdown. How can I do the same for Free BSD?
Runlevel is a concept specific to
The concept of runlevel also does not exist in BSD-style init, hence no runlevels in FreeBSD.
Mikhail is correct in that there are no Linux/SysV style run levels, however there is single and multi-user mode. This is roundabout but the best way I've discovered to tell if you're in single or multi-user programmatically:
When FreeBSD is in single user mode "adjkerntz" hasn't been started yet (and it is killed if you drop back down, too), so you can test for that:
I have verified this works under 9.x and 10.x and likely all other versions of FreeBSD.
