Not sure what the problem is here...

Why can't you do something like rc=$? after you do whatever it is you are trying to do then check, if [[ $rc -eq 0 ]]; then ... fi

Hi,

For example, the return value from database is

data->> (return status = 0)
0

but i just wan to get "0" to assign into another new declaration.
if i do like this : rc=$data

rc will still get (return status = 0)
0

i just wan to get the specific "0", remove the others.

Thank you

Not sure if I understand totally but I think you want the '0' after the words "return status = "? Maybe this will give you some direction...

Assuming data="(return status = 0)"

rc=`echo $data|cut -d"=" -f2|cut -c1-2`
echo data=$data
echo $rc

----
output:
data=(return status = 0)
0

Thank you giannicello... the way u teach me is working fine... but i did change a bit,
Thank you so much....

The command show below is the way i changed... coz some return value is -1 or -2 or 0, and i have to get the number value is outside the branket... Thank you so much..

rc=`echo $result|cut -d")" -f2|cut -c1-3|cut -d" " -f2`
rc=-1

done...
