Shell Script Issue can't find the total size

I have created a shell script that would read a text file and will find the size of the file. The problem is its not giving the total file size.

For example when I execute ./sushant7.sh I get:

Size is 4.0K    lesurvey1
Size is 4.0K    tbbsr11d1def
Size is 4.0K    tbbsr11d1def

I want to get 12k as total which I am not able to.

My script is

FILE1=/home/dev/sushanttest

cd $FILE1

while read file
do
    echo "Size is ` du -ha  $file`"

done < /home/dev/sushanttest/listing.txt

Perhaps you could make use of the -b switch as well to du to print out the size in bytes. For example:

$ du -cb FILE_GLOB | grep total | awk '{print $1}'

You can use this:

xargs du -ch < /home/dev/sushanttest/listing.txt | grep total

This gives all the files as an argument to a single du call. If you iterate yourself over the files, you'll have to sum up yourself.
