Shell Programming and Scripting

Hi

I try to run a command using bash script. The script should now look like this:
#!/bin/bash
case "$1" in

start)
sudo su - cispmgm -c "/usr/local/jdk/bin/java -Dworking.dir=/opt/ibm/cisp -Denvironment.target= -Xms512M -Xmx1024M -classpath /opt/ibm/cisp/:/opt/ibm/cisp/conf:/opt/ibm/cisp/lib/AIB-CispClient-1.2.0-SNAPSHOT.jar ch.coop.aib.v1.job.Run -d /opt/ibm/cisp --start">/opt/ibm/cisp/log/console.log 2>&1 &
;;
stop)
;;

restart)
$0 stop
sleep 30
$0 start
;;

*)

echo "usage: $0 (start|stop|restart)"

esac


If I start the script as a normal user with the following command: ./startcisp.sh start

If the command is executed twice in the script:

cispmgm 7404 1 0 10:43 pts/3 00:00:00 su - cispmgm -c /usr/local/jdk/bin/java -Dworking.dir=/opt/ibm/cisp -Denvironment.target= -Xms512M -Xmx1024M -classpath /opt/ibm/cisp/:/opt/ibm/cisp/conf:/opt/ibm/cisp/lib/AIB-CispClient-1.2.0-SNAPSHOT.jar ch.coop.aib.v1.job.Run -d /opt/ibm/cisp --start
cispmgm 7405 7404 11 10:43 ? 00:00:02 /usr/local/jdk/bin/java -Dworking.dir=/opt/ibm/cisp -Denvironment.target= -Xms512M -Xmx1024M -classpath /opt/ibm/cisp/:/opt/ibm/cisp/conf:/opt/ibm/cisp/lib/AIB-CispClient-1.2.0-SNAPSHOT.jar ch.coop.aib.v1.job.Run -d /opt/ibm/cisp --start

if I kille Task 7405 (the second), the first task is terminated automatically. If I but the task kille 7404, continues the second and the program also runs correctly.

What can I do so I do not get two tasks?
My system is a Linux.

Thanks for the help and greetings

One process is the su shell.
You can
exec /usr/local/jdk/bin/java ...
Or omit su, simply run
sudo -u cispmgm /usr/local/jdk/bin/java ...
