  NAME

    ruptime - Shows host status for each machine on the local network

  SYNOPSIS

    ruptime [-a] [-l|-t|-u] [-r]

  FLAGS

    -a   Includes in the listing users idle an hour or more.

    -l   Sorts the listing by load average.

    -t   Sorts the listing by uptime.

    -u   Sorts the listing by number of users.

    -r   Sorts the listing in reverse order.

  DESCRIPTION

    The ruptime command displays a status line for each machine on the local
    network running rwhod.  The status line provided by ruptime is a summary
    of the current activity on each system.  This data is provided by packets
    broadcast by each host once every three minutes.

    Machines for which a status report has not been received in the last five
    minutes are shown as being down.

    Users idle an hour or more are omitted from the listing unless the -a flag
    is specified.  By default, the listing is sorted by hostname.

  EXAMPLES

    2.  To show host status sorted by load average including users idle an

    3.  To show host status for each machine on the LAN sorted by uptime in
        reverse order, enter:

        ruptime -tr
