.Sh NAME
.Nm ruptime
.Nd show host status of local machines
.Sh SYNOPSIS
.Nm
.Op Fl alrtu
.Op Ar host ...
.Sh DESCRIPTION
The
.Nm
utility gives a status line like
.Xr uptime 1
for each machine on the local network; these are formed from packets
broadcast by each host on the network once every three minutes.
.Pp
If no operands are given,
.Nm
displays uptime status for all machines;
otherwise only those hosts specified on the command line are displayed.
If hosts are specified on the command line, the sort order is equivalent
to the order hosts were specified on the command line.
.Pp
Machines for which no status report has been received for 11
minutes are shown as being down, and machines for which no status
report has been received for 4 days are not shown in the list at all.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
Include all users.  By default, if a user hasn't typed to the system for
an hour or more, then the user will be omitted from the output.
.It Fl l
Sort by load average.
.It Fl r
Reverse 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.

Add functionality to only list hosts specified on the command line. If none are specified the old behaviour is old. The submitted applied a much cleaner diff to ruptime.c, however it did not cover cases like listing failures. It would probably be a good idea to move the printing from the ruptime function, and have that function just be used to build the list, as that would unbreak sorting, but this diff is intended to be clear, relative to the original code. As the sort order is the order specified on the command line, for now, such is documented in the manual page accordingly. Submitted by: Edward J. M.
