Shows the actual size of files in Thunar. Thunar has a strange problem of not reporting the correct size of files.

file-size.sh

#! /bin/bash

kb=$((2**10))
mb=$((2**20))

for file in $@; do
        if [ ! -e $file ]; then
                continue
        fi
     b1=`ls -l $file | cut -d" " -f5`
     let "b += b1"
done
     k=`echo -e "scale=2; $b/$kb" | bc`
     m=`echo -e "scale=2; $b/$mb" | bc`
