stopping and restarting the system

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm halt
|
|
and
|
|
.Nm 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 login
|
|
accounting file.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl n
|
|
If the
|
|
.Fl n
|
|
option is specified,
|
|
the file system cache is not flushed.
|
|
This option should probably not be used.
|
|
.It Fl q
|
|
If the
|
|
.Fl q
|
|
option is specified,
|
|
the system is halted or restarted quickly and ungracefully, and only
|
|
the flushing of the file system cache is performed.
|
|
This option should probably not be used.
|
|
.It Fl p
|
|
If the
|
|
.Fl p
|
|
option is specified, then the system will turn off the power
|
|
if it can. This is of course likely to make
|
|
.Nm reboot
|
|
rather similar to
|
|
.Nm halt.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm fasthalt
|
|
and
|
|
.Nm fastboot
|
|
utilities are nothing more than aliases for the
|
|
.Nm halt
|
|
and
|
|
.Nm reboot
|
|
utilities.
|
|
.Pp
|
|
Normally, the
|
|
.Xr shutdown 8
|
|
utility is used when the system needs to be halted or restarted, giving
|
|
users advance warning of their impending doom.
