Shell - 对比两个文件MD5值函数封装

#!/bin/bash

file1="/opt/test1"
file2="/opt/test2"


# 函数内的exit,可以退出整个sh脚本,不再执行后续的步骤
compareMD5() {
    file1="$1"
    file2="$2"

    md5_1=$(md5sum "$file1" | awk '{print $1}')
    md5_2=$(md5sum "$file2" | awk '{print $1}')

    if [ "$md5_1" = "$md5_2" ]; then
        echo "MD5 values are the same"
    else
        echo "MD5 values are different"
	      exit 1  
    fi
}

compareMD5 $file1 $file2

echo "------ end ------"
