rusers

rusers(1)						      General Commands Manual							 rusers(1)

NAME

       rusers - Display a list of users who are logged in to a remote machine

SYNOPSIS

       rusers [-ahilu] host...

OPTIONS

       Give  a	report for a machine even if no users are logged in.  Sort alphabetically by host name.  Sort by idle time.  Give a longer listing
       in the style of who(1).	Sort by number of users.

DESCRIPTION

       The rusers command displays information about users and processes running on remote machines.   The  listing  is  in  the  order  in  which
       responses are received, but this order can be changed by specifying one of the options listed in the OPTIONS section.

       By default the rusers command prints the names of the users logged in.	When the -l option is given, additional information is printed for
       each user, as follows:

       userid hostname:terminal login date login time idle time login host

       If hostname and login host are the  same  value, the login host field is not displayed.	Likewise, if hostname is not idle, the	idle  time
       is not displayed. A remote host only responds if it is running the rusersd daemon, which may be started from the inetd daemon or the listen
       function.

SEE ALSO

       Commands: who(1), inetd(8)

       Functions: listen(2)
