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.

|
If the
|
|
|
|
|
.Fl d
|
|
|
|
|
option is specified,
|
|
|
|
|
the system will create a dump before rebooting.
|
|
|
|
|
This option is useful for debugging system dump procedures or
|
|
|
|
|
capturing the state of a corrupted or misbehaving system.
