Hi Yoda,

I have finally been able to solve it Smilie, by using below code...
And yes I was calling this function from the mail script. Regarding the echo 0 part, yes I had added it later on, just to check whats the value chaging from & to.
Thanks for you help though....
Code:
while read line
        do
                if [ "$Name" = "$line" ]
                then
                        tempvar=`expr $tempvar + 1`
                        echo $tempvar
                        exit
                fi
        done < $dirUser/names.txt > file.txt
        
newvar=`cat file.txt | head -1`

        if [ $newvar -eq 0 ]
        then
                echo "This is not a valid name... Exiting"
                exit
else
echo "valid"
        fi

& I am getting valid this time finally Smilie

Even though it is working, what you did is not a good programming practice. I highly recommend implementing the suggestion posted by Don Cragun in his previous post.

No. No. No. If you find a matching name in names.txt, this script exits before it gets to the echo "valid".

Something else is going on that you are not showing us.

This one works:
Code:
 while read line
        do
                if [ "$Name" = "$line" ]
                then
                        tempvar=`expr $tempvar + 1`
                        echo $tempvar
                        exit
                fi
        done < $dirUser/names.txt > file.txt
        
newvar=`cat file.txt | head -1`
        if [ $newvar -eq 0 ]
        then
                echo "This is not a valid name... Exiting"
                exit
else
echo "valid value"
        fi

& the value is finally valid outside the loop...
Thanks everyone for your help, though Smilie
