ruptime - show host status of local machines
Ruptime gives a status line like uptime for each machine on the local
network; these are formed from packets broadcast by each host on the net-
work once a minute.
Machines for which no status report has been received for 11 minutes are
shown as being down.
The options are as follows:
-a Users idle an hour or more are not counted unless the -a flag is
-l Sort by load average.
-r Reverses the sort order.
