halt(8) |
 |
reboot, halt, poweroff − reboot or stop the system
reboot [OPTION]...
halt [OPTION]...
poweroff [OPTION]...
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.
|
-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. |
This tool is provided for compatibility with the traditional System V init(8).
