could any one tell me why i m not getting the value of variable i outside the
while loop in file reading
cat filename | while read line
do
i=2
done
echo $i
here it is not showing the value of i . what i have to do if i want to persist the value of
i outside the while loop
thanks
In this case, the pipe spawns a sub-shell and assigns i=2. When it comes out of the subshell, it does retain the value of i. Think scoping and you will understand.
Do this and you will get what you are looking for
