The `s6-poweroff` program

-s6-poweroff syncs the filesystems and halts the machine -immediately, switching the power off if possible. -

- -

- This is different from the sysvinit poweroff -command, which performs shutdown. The -s6-linux-utils s6-poweroff command is more or less equivalent to -sysvinit's poweroff -f. +s6-poweroff sends a signal to process 1 in order to power off the machine; +or, with the -f option, it performs an immediate hard shutdown.

Interface

-     s6-poweroff
+     s6-poweroff [ -h | -p | -r ] [ -f ]

s6-poweroff sends a signal to process 1.
It then exits 0.

Options

+ +

-h : halt. The command will order a halt (i.e. the system will +be shut down, but the power will remain up), which means +sending a SIGUSR2 to process 1.
-p : poweroff. The command will order a power off, which means +sending a SIGUSR1 to process 1. This is the default.
-r : reboot. The command will order a reboot, which means +sending a SIGINT to process 1.
-f : force. The command will not send any signal to process 1; +it will just sync the filesystems then tell the kernel to halt, poweroff or reboot. +s6-reboot -f or s6-poweroff -f should be the last program +executed in the lifetime of a machine, at the end of the shutdown script called +by process 1 when it receives a signal telling it to shut down.
