+.Nd show host status of local machines
+.Sh SYNOPSIS
+.Nm ruptime
+.Op Fl alrtu
+.Sh DESCRIPTION
+.Nm Ruptime
+gives a status line like
+.Ar uptime
+for each machine on the local network; these are formed from packets
+broadcast by each host on the network once a minute.
+.Pp
+Machines for which no status report has been received for 11
+minutes are shown as being down.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a
+Users idle an hour or more are not counted unless the
+.Fl a
+flag is given.
+.It Fl l
+Sort by load average.
+.It Fl r
+Reverses the sort order.
+.It Fl t
+Sort by uptime.
+.It Fl u
+Sort by number of users.
+.El
+.Pp
+The default listing is sorted by host name.
+.Sh FILES
