REBOOT(8)						    BSD System Manager's Manual 						 REBOOT(8)

NAME
     reboot, halt -- stopping and restarting the system

SYNOPSIS
     halt [-lnq]
     reboot [-lnq]

DESCRIPTION
     The halt and reboot utilities flush the file system cache to disk, send all running processes a SIGTERM (and subsequently a SIGKILL) and,
     respectively, halt or restart the system.	The action is logged, including entering a shutdown record into the wtmp(5) file.

     The options are as follows:

     -l      The halt or reboot is not logged to the system log.  This option is intended for applications such as shutdown(8), that call reboot
	     or halt and log this themselves.

     -n      The file system cache is not flushed.  This option should probably not be used.

     -q      The system is halted or restarted quickly and ungracefully, and only the flushing of the file system cache is performed (if the -n
	     option is not specified).	This option should probably not be used.

     Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending
     doom and cleanly terminating specific programs.
