Script to check users logged out

Hi,

Here is the script that I have written to check if a particular user is has logged out, and if yes, then a mail needs to be sent to the management the details of whatever has been captured by the script command.

echo "The current users are:"

who | awk '{print $1}' | sort > temp1
cp temp1 temp2
more temp1

while true
do
who | awk '{print $1}' | sort > temp2
cmp -s temp1 temp2

case "$?" in

1)
user="absprod1"
file=`grep $user temp1 temp2 | cut -c 1-5`
echo $file
file1=`echo $file | cut -c 1-5`
echo $file1

if [ $file1 = "temp1" ]
then echo "User "$user" has logged out." | mail -s "Logged out" abc@xyz.com
cat /home/absprod1/test_audit | mail -s "Audit report" abc@xyz.com
fi
esac

rm temp1
mv temp2 temp1
rm /home/absprod1/test_audit
return
done

My question is how to have this script executed continuously so that, it captures every logout of the user id absprod1? Can anyone please help me?

rusers

RUSERS(1)						    BSD General Commands Manual 						 RUSERS(1)

NAME

     rusers -- who is logged in to machines on local network

SYNOPSIS

     rusers [-al] [host ...]

DESCRIPTION

     The rusers command produces output similar to who, but for the list of hosts or all machines on the local network. For each host responding
     to the rusers query, the hostname with the names of the users currently logged on is printed on each line. The rusers command will wait for
     one minute to catch late responders.

     The following options are available:

     -a      Print all machines responding even if no one is currently logged in.

     -l      Print a long format listing. This includes the user name, host name, tty that the user is logged in to, the date and time the user
	     logged in, the amount of time since the user typed on the keyboard, and the remote host they logged in from (if applicable).

DIAGNOSTICS

     rusers: RPC: Program not registered
	     The rpc.rusersd(8) daemon has not been started on the remote host.

     rusers: RPC: Timed out
	     A communication error occurred.  Either the network is excessively congested, or the rpc.rusersd(8) daemon has terminated on the
	     remote host.

     rusers: RPC: Port mapper failure - RPC: Timed out
	     The remote host is not running the portmapper (see portmap(8) ), and cannot accomodate any RPC-based services.  The host may be down.

SEE ALSO

     rwho(1) users(1), who(1), portmap(8), rpc.rusersd(8)

HISTORY

     The rusers command appeared in SunOS.

BUGS

     The sorting options are not implemented.
