+.Dt RC.SHUTDOWN 8
+.Os
+.Sh NAME
+.Nm /etc/rc.shutdown
+.Nd command script run at system shutdown
+.Sh DESCRIPTION
+When the system is administratively shut down using either the
+.Xr reboot 8
+or
+.Xr halt 8
+command, either of these programs checks for the existence of a
+.Pa /etc/rc.shutdown
+script to run before halting the system. It will also be executed by
+.Xr init 8
+if a keyboard-requested halt is issued (for architectures that support this).
+.Pp
+Currently, the
+.Nm
+script does nothing but save part of the entropy pool for reuse on reboot, but
+extra commands may be added by the system administrator.
+.Sh SEE ALSO

+.Xr init 8 ,
+.Xr rc 8 ,
