RUPTIME(1)                               BSD General Commands Manual                              RUPTIME(1)

NAME
     ruptime -- show host status of local machines

SYNOPSIS
     ruptime [-alrtu] [host ...]

DESCRIPTION
     The ruptime utility gives a status line like 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.

     If no operands are given, ruptime 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.

     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.

     The options are as follows:

     -a      Include all users.  By default, if a user has not typed to the system for an hour or more, then
             the user will be omitted from the output.

     -l      Sort by load average.

     -r      Reverse the sort order.

     -t      Sort by uptime.

     -u      Sort by number of users.

     The default listing is sorted by host name.
