sudo reboot -nq
-n
file system cache not flushed
-q
restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n option is not specified)
Notes:

-q
, then-qn
. - Wait 5-15 minutes.
- Don't expect a shutdown acknowledgement.
- A "Broken pipe" disconnect message appears later then with regular reboots.
This is a uncontrolled shutdown and the only worse thing for data / filesystem is holding the power button, but if you've already quit all the apps that can quit and waited 10 minutes, it's not likely a clean landing can happen at this point.
