PHP scope of a Variable inside shell script
hi all,

i'm using the following script,
Code:
Status=1
Function_do ()
{
while read line;
do
    if [ ` echo $line | grep 'symbol not found:' | wc -l` -eq 1 ]; then
        #echo $line
        if [ ! `echo $line | grep 'kxdfhei1' | wc -l ` -eq 1  -o  ! `echo $line | grep 'main' | wc -l ` -eq 1 ]; then
            Status=0
            echo " LINKINK ERROR "
        fi
    fi
done < ldd.log
}

Function_do
echo " Status = $Status "

OUTPUT:
Code:
LINKINK ERROR
Status = 1

What happen to the value of Status=0 that i set inside If condition? What happens if use while? the same script if i use for loop it is giving proper output.. status=0. I'm not able to understand the logic behind it. Can any one help me in this?


Regards,
Vijay
