I had read that you can "quietly shut down to single user mode" by running, within terminal:
sudo shutdown now
This sounds far preferable to having to restart the computer and hold CMND+S. However - at least in Mavericks it doesn't seem to work.
shutdown: -h, -r, -s, or -k is required usage: shutdown [-] [-h [-u] [-n] | -r [-n] | -s | -k] time [warning-message ...]
I thought that anything within square brackets was optional.
When I run it with the
-k flag (which kicks all users off):
sudo shutdown -k now, the output is:
Shutdown NOW! *** FINAL System shutdown message from user@computer_name *** System going down IMMEDIATELY System shutdown time has arrived but you'll have to do it yourself
Then if I try to open a new terminal:
NO LOGINS: System going down at 12:53 #my password Login incorrect login:
Restarting again and terminal login is restored.
Can anyone offer some insight as to what's going on here?
