Say that on the server we start the Xclock app (as an example) for

$ Xclock -update 1 -display <IP address of client_1> &

$ Xclock -update 1 -display <IP address of client_3> &

ps output shows 3 Xclock process then 2 when one user close the app.
This is fine but we cannot tell which user has close the app.



#!/bin/sh

USERS="user1 user2 user3"
SLEEPTIME=600

while true
do
for i in $USERS
do
PID="`pgrep -U $i Xclock`"
if [ $? -ne 0 ]
then
echo run program to start $i
fi
done
sleep $SLEEPTIME
done

This works when you have 3 users issuing each the xclock start command.
But it fails if only one user(at the server) is issuing it 3 time (to
display xclock on each ThinClient)
as if we had USERS="UniqueUser" in above script. That's the problem we try
to solve.
Anyway, thanks for your interest.
