UPTIME(1N)              COMMAND REFERENCE              UPTIME(1N)



NAME
     uptime - show status of hosts on network

SYNOPSIS
     uptime [ -l ][ -t ][ -u ][ -U ][ -r ][ -w seconds ][
     hostname ]...

DESCRIPTION
     Uptime with no arguments, prints statistics about the local
     host.  The statistics include the current time, the length
     of time the system has been up, how many users are currently
     logged on, and the average number of jobs in the run queue
     over the last one, five, and fifteen minute time periods.

     Uptime can also be used to obtain similar statistics from
     other hosts on the network.  If any of the options are
     specified but no hostname is given, uptime will broadcast
     for uptime statistics on the local area network.  Normally
     uptime will listen for responses for 10 seconds and then
     display them.  If desired, the timeout period can be
     lengthened or decreased through the -w [seconds] option.

     Hosts which at one time responded to an uptime request, but
     did not respond to the most recent request, will be marked
     as "down".  A host that is down for more than 5 days will be
     deleted from the uptime data base (in /usr/spool/uptime ).

     If one or more hostnames is specified on the uptime command
     line, uptime will interogate only those hosts for the
     statistics.  Also, by specifying a hostname, it is possible
     to get uptime statisitics from hosts on other connected
     networks and not just the local network.

OPTIONS
     -l   Sort status lines by load average.

     -r   Generate status lines for remote systems current to the
          minute.

     -t   Sort status lines by uptime.

     -u   Sort status lines by number of users.

     -w   [seconds] When broadcasting for uptime statistics (i.e.
          when no hostname is specified), the -w [seconds] option
          determines how long uptime waits collecting responses.

     -U   Generate a list of host systems that are up, one name
          to a line.  This is useful for shell programs.

FILES
     /usr/spool/uptime/up.*   Data files.
