Halt, power-off, or reboot the entire system.

  • halt instructs the hardware to stop all CPU functions but leaves the system in a powered-on state. This usually means someone has to shut down the machine manually by pressing the power button afterwards.

  • poweroff stops the CPU but also sends an ACPI hardware signal which instructs the system to commence with a complete and immediate shutdown. This is roughly equivalent to pressing the power button on a typical desktop computer.

  • reboot reboots the system.
