 Hi,

 I am a lame Bourne sheel programmer, how to write:

 while [ ( $? -ne 0 ) -a ( $retry -gt 0 ) ] ; do

 that should execute as long as $? is not null and $retry is greater
 than 0?

Try something like...

retry=0
done=-0
while [ $done -eq 0 ]  [ $retry -lt 10 ]; do

run_some_other_stuff_here

if [ $? -eq 0 ]; then
done=1
fi
done

if [ $done -eq 0 ]; then
echo Failed after $retry attempts.
fi
