#!/bin/sh

 

if [ $# -ne 2 ] ; then
        echo  "Input: $(basename $0) path filename"
        exit -1
fi

 

find $1 -name "$2" -exec du -h {} \; | awk '{if($1~"G") {printf("%s\n",$1);gsub("G","");$1=$1*1000*1000} else if($1~"M") {printf("%s\n",$1);gsub("M","");$1=$1*1000} else if($1~"K") {printf("%s\n",$1); gsub("K","")};sum+=$1} END{printf("\nsum=%dM\n",sum/1000)}'

exit 0
