md5.sh

declare -r dir="$1"
declare -r md5txt="${dir}"/md5txt
for file_name in ${dir}/*
do
    md5=`md5sum $file_name | cut -d ' ' -f1`
    txt="\"${file_name}\":${md5}"
    echo ${txt} >> md5txt
done

declare -r sha512txt="${dir}"/sha512txt
for file_name in ${dir}/*
do
    sha512=`sha512sum $file_name | cut -d ' ' -f1`
    txt="\"${file_name}\":${sha512}"
    echo ${txt} >> sha512txt
done

运行：
bash ./md5.sh ./

结果：
