Hi Franz,

Halt does not power off. It just brings system to halt state. Whether halt is equivalent to power off depends on your system's BIOS. They are all different and treat the command differently. On the machines I tinker with, about half will proceed to poweroff, and half will just halt (with power still on).

To truly get to power off every time, use

poweroff

To reboot, use

reboot

Aside from being convenient, they are clearer commands that do what they say.
