shutdown schedules a time for the system to be powered down. It may be used to halt, power-off or reboot the machine.
shutdown -h
is equivalent to : shutdown --poweroff simply it means POWEROFF.
in the other hand
shutdown -H
or
shutdown --halt
instructs the hardware to stop all CPU functions, but leaves it powered on. You can use it to get the system to a state where you can perform low level maintenance.
Note that in some cases it completely shuts down the system. Below are examples of halt
