Hi guys - Thanks for your responses the last piece of code is really what I think I need. I'm basically looking for concurrent users within a 15 mins period in a 24hr file so I think the last bit of code would do it. Can I also ask if my file name is called users.out where would I read this in - Would I cat the file then run the awk code you've kindly given me? Thanks in advance

rusers(1) General Commands Manual rusers(1)
NAME
rusers - determine who is logged in on machines on local network
SYNOPSIS
[host ...]
DESCRIPTION
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, 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 option is given, uses an out-
put 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
recognizes the following command-line options:
Give a report for a machine even if no users are logged in on it.
Sort alphabetically by host name.
Sort by idle time.
Give a longer listing in the style of
(see who(1)).
Sort by number of users.
RETURN VALUE
returns exit code zero if no errors are encountered; otherwise it returns the number of errors found.
AUTHOR
was developed by Sun Microsystems, Inc.
WARNINGS
Broadcasting does not work through gateways; therefore, does not report information about machines that are reached only through gateways.
