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

How to write a condition in Bourne shell

[Olivier Nicole]

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?

TIA,

Olivier
