Mac issue with service restart

[dracoyinyang]

In this part of the .sh file

status=$(launchctl list | grep com.labtechsoftware.LTSvc)
if [ -z "$status" ]; then
launchctl stop com.labtechsoftware.LTSvc
launchctl start com.labtechsoftware.LTSvc
status=$(launchctl list | grep com.labtechsoftware.LTSvc)
if [ -z "$status" ]; then
statusName="Stopped"
else
statusName="Running"
fi
else
statusName="Running"
fi

It appears that the service gets restarted.

problem is on all the macs I have I have to run the restart of the service manually before it will even notice the service has been upgrade.
