ruptime Command
  
  
  Purpose
  
  Shows the status of each host on a network.
  
   Syntax
  
  ruptime [ -a] [ -r] [ -l |  -t |  -u]
  
  Description
  
  The /usr/bin/ruptime command displays the status of each host
  that is on a local network and is running the  rwhod daemon.  The
  status lines are sorted by host name unless the  -l,  -t, or  -u
  flag is indicated.  The status information is provided in packets
  broadcast  once every 3 minutes by each network host running  the
  rwhod daemon.  Any activity (such as power to a host being turned
  on or off) that takes place between  broadcasts  is not reflected
  until the next broadcast.   Hosts for which no status information
  is received for 11 minutes are reported as down.
  
  Output is in the following fomat: hostname, status, time, number
  of  users,  and  load  average.  Load average represents the load
  averages  over  5-, 10-,  and  15-minute  intervals  prior  to  a
  server's transmission.  The load averages are multiplied by 10 to
  represent the value in decimal format.
  
  Flags
  
  -a 	Includes all users.  Without this flag, users whose sessions
  are idle an hour or more are not included.
  
  -l	Sorts the list by the load average.
  
  -r	Reverses the sort order.  The -r flag should be used with the
  -l, -t or -u flag.
  
  -t	Sorts the list by the uptime.
  
  -u	Sorts the list by the number of users.
