          Use the -B1 parameter to du:



          du -s -B1 foldername



          $ man 1 du
          -B, --block-size=SIZE
          use SIZE-byte blocks



          You could also try the --apparent-size flag

              This gives a different number - did you actually try?

            du - estimate file space usage



            -B, --block-size=SIZE
            scale sizes by SIZE before printing them. E.g., '-BM' prints sizes in units of 1,048,576 bytes. See SIZE format below.

            -b, --bytes
            equivalent to '--apparent-size --block-size=1'


            For Example,



            user$ du -B1 filename
