If your system has it, use the halt command.

The traditional command is

shutdown -h +1 "System is going down!"

where the +1 gives everyone 1 minute after the warning message before shutting down.  The -h says halt the system (i.e. don't reboot). The last arg is the warning message given to users.  If you want it to go down now use the word "now" in place of +1.
