Have you tried to write a function for it !!

for instance: after the code that you have wrote you can check its return value by
echo $?
if the output was zero, so the command has executed properly,
if output was 1 thats mean the command didnt work properly

try to write if for it, like

if ((echo $?==0 ))
then
break;
fi

I hope to be what you are looking for
