NAME

reboot, halt, poweroff - reboot or stop the system

SYNOPSIS

reboot [OPTION]...

halt [OPTION]...

poweroff [OPTION]...

DESCRIPTION

These utilities allow a system administrator to reboot, halt or poweroff the system.

When called without the -f option, they simply invoke shutdown(8) with the appropriate arguments.

OPTIONS

-f
Does not invoke shutdown(8) and instead performs the actual action you would expect from the name. This is generally used from the event handler itself.
-n
Does not call sync(2) before performing the reboot; this could result in data loss. On Linux, this probably has no effect as the kernel flushes all write buffers before shutting down.
-h
Iterates /proc/ide to find all IDE disk drives and requests that they enter a standby mode before shutting down. On Linux, this is unnecessary as the kernel will do this anyway.
-i
Iterates configured network interfaces and brings them down before shutting down. On Linux, this is unnecessary as the kernel will do this anyway.
-p
Instructs the halt command to instead behave as poweroff.

NOTES

This tool is provided for compatibility with the traditional System V init(8).
