NAME
rusers — determine who is logged in on machines on local network
SYNOPSIS
rusers
[-a]
[-h]
[-i]
[-l]
[-u]
[host ...]
DESCRIPTION
rusers
produces output similar to the "quick" option of
who(1),
but for remote machines.
It broadcasts on the local network and prints the responses it receives.
Though the listing is normally in the order that responses are received,
the order can be changed by specifying a command-line option.
The broadcast process takes about two minutes.
When
host
arguments are given, instead of broadcasting,
rusers
only queries the list of specified hosts.
For each machine, the default is to print a line
listing the host name and all users on that host.
When the
-l
option is given,
rusers
uses an output format similar to
rwho(1).
If a user has not typed on the system for a minute or more,
the idle time is reported.
A remote host only responds if it is running the
rusersd(1M)
daemon.
Options
rusers
recognizes the following command-line options:
- -a
Give a report for a machine even if no users are logged in on it.
- -h
Sort alphabetically by host name.
- -i
Sort by idle time.
- -l
Give a longer listing in the style of
who-R
(see
who(1)).
- -u
Sort by number of users.
RETURN VALUE
rusers
returns exit code zero if no errors are encountered;
otherwise it returns the number of errors found.

does not report information about machines
that are reached only through gateways.
