#!/bin/bash

# 参数校验，必须输入目录
if [ $# -eq 0 ];then
    echo "usage: $0 <folder> "
    exit 0
fi

# 刨除目录末尾的/
folder=${1%/}
# 判断目录是否为空
if [ ! -d $folder ];then
    echo "$(date) [INFO] $folder isn't a directory"
    exit 127
fi

# 遍历目录下所有的文件
for file in `find ${folder} -type f`; do
    md5sum $file | sed 's#'${folder}'/##g' 
done
