So, I opened up single-user mode to show my friend how easy it was for a Mac to be directly hijacked if someone was able to steal the physical lap top (as opposed to hijacking remotely using SSH), and I couldn't exactly remember which
shutdown now option to use (fortunately, I was prompted by the command line), so I defaulted to
-h. Should I be worried if I use
-h instead of
-r? Is there any difference between these commands?
shutdown -h now shutdown -s now shutdown -r now shutdown -k now
