.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility gives a status line like
|
|
.Xr 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.
|
|
.Pp
|
|
If no operands are given,
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Include all users.

|

an hour or more, then the user will be omitted from the output.
