Shutdown

Compared to some GNU/Linux flavors, “shutdown -h now“ command just halts the FreeBSD, not turns off the power. Refer the following screen shot from my Virtual Machine:

You can see, after running “shutdown -h now“, the system is just halted, and press any key can reboot the system immediately.

If you want to halt and power off the system, you should execute “shutdown -p now“.
