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 network once a minute. Machines for which no status report has been received for 11 minutes are shown as being down. Options: -a Users idle an hour or more are not counted unless the -a flag is given. -l Sort by load average. -r Reverses the sort order. -t Sort by uptime. -u Sort by number of users. The default listing is sorted by host name.
