Triggers the software shutdown procedure. Performs an immediate hardware shutdown with the ‑f option. It is normally invoked by 66 halt, 66 poweroff or 66 reboot command. This program is a modified copy of s6-linux-init-hpr.
This program is primarily used internally by 66. User may prefer to use 66 halt, 66 poweroff or 66 reboot instead.
66-hpr [ -H ] [ -l live ] [ -b banner ] [ -f ] [ -h | -p | -r ] [ -n ] [ -d | -w ] [ -W ]If the -f option is passed the system is stopped or rebooted immediately without properly cleaning up.
Else the machine's shutdown procedure is started.
The command exits 0; the shutdown procedure happens asynchronously.
This is the traditional sysvinit interface for the halt, poweroff and reboot programs. 66‑hpr must always be called with either ‑h, ‑p or ‑r.
-H: prints this help.
-l live: changes the supervision directory of service to live. By default this will be /run/66. The default can also be changed at compile time by passing the --livedir=live option to ./configure. An existing absolute path is expected and should be within a writable and executable filesystem - likely a RAM filesystem—see 66 scandir.
-b banner: Text to display before executing the shutdown process. Defaults to:
*** WARNING ***
The system is going down NOW!-f: force. The command will not trigger a clean shutdown procedure; it will only sync the filesystems then tell the kernel to immediately halt, poweroff and reboot. This should be the last step in the lifetime cycle of the machine.
-h: halt. The system will be shut down but the power will remain connected.
-p: poweroff. Like halt but the power will also be turned off.
-r: reboot. The system will initialize a warm boot without disconnecting power.
-n: Do not call sync() before the hardware shutdown. The default is to sync, just in case. This option is only relevant when combined with -f; without it, it has no effect.
-d: Do not write a wtmp shutdown entry—see utmp,wtmp and btmp.
-w: Only write a wtmp shutdown entry; does not actually shut down the system.
-W: Do not send a wall message to users before shutting down the system. Some other implementations of the halt, poweroff and reboot commands use the ‑‑no‑wall long option to achieve this.
