Name
reboot, halt, poweroff - reboot or stop the system
Synopsis
reboot [OPTION]...

halt [OPTION]...

poweroff [OPTION]...
Description
These programs allow a system administrator to reboot, halt or poweroff
the system.

When called with --force or when in runlevel 0 or 6, this tool invokes
the reboot(2) system call itself and directly reboots the system.
*Otherwise this simply invokes the shutdown(8) tool with the appropriate
arguments*.
