I know I can shutdown a mac via terminal using

sudo shutdown -h now

But that is a graceful shutdown how can I force it to immediately die (I know this is bad practice)

ditto for rebooting

there doesn't appear to be an argument for --force or such.

    Have a look at reboot -q. This isn't a graceful shutdown. See the manpages for reboot, halt and shutdown for more information. Why do you not want a graceful halt or reboot?

  • man shutdown has (as any other man page) a SEE ALSO section which might be useful in these cases.
