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, respec‐
     tively, 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 proba‐
	     bly 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.

SEE ALSO
     wtmp(5), shutdown(8), sync(8)
