One reason to use the shutdown command rather than halt or init 6 or the three finger salute is that shutdown generally issues the sync system call and shuts down your system properly.
from man halt: Halt notes that the system is being brought down in the file /var/log/wtmp, and then either tells the kernel to halt, reboot, poweroff or suspend the system. If halt or reboot is called when the system is not in runlevel 0 or 6, shutdown(8) will be invoked instead (with the flag -h or -r). So it is the same, and shorter to type. And about the three finger salute, file '/etc/inittab' contains this: # what to do when CTRL-ALT-DEL is pressed ca::ctrlaltdel:/sbin/shutdown -h -t 4 now So it is also the same. -- Cheers, Carlos Robinson
