关于使用java执行shell脚本获取centos的硬盘序列号和mac地址

1.获取硬盘序列号:

新建shell脚本文件: identifier.sh, 内容为:

 diskdata=`fdisk -l`
 diskleft=${diskdata#*"identifier: "}
 identifier=${diskleft%%" Device Boot"*}
 echo ${identifier}

调整identifier.sh的权限:

 chmod +x identifier.sh

使用Java代码去调用该shell脚本获取结果

 private static String getIdentifier() throws Exception {
     String path = "/usr/local/webapp/identifier.sh";
     Process process = Runtime.getRuntime().exec(path);
     process.waitFor();

     BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
     StringBuffer sb = new StringBuffer();
     String line;
     while ((line = br.readLine()) != null){
         sb.append(line);
     }
     String str = sb.toString();
     return str;
 }

2. 获取MAC地址:

新建shell脚本文件: macAddress.sh, 内容为:

 macAddress=`ifconfig | awk -F'[ :]+' '!NF{if(eth!=""&&ip=="")print eth;eth=ip4=""}/^[^ ]/{eth=$1}/inet addr:/{ip=$4}'`
 ifconfig ${macAddress[]} | grep "ether" | awk '{print $2}'

调整macAddress.sh的权限:

 chmod +x macAddress.sh

使用Java代码去调用该shell脚本获取结果

 private static String getMACAddress() throws Exception {
     String path = "/usr/local/webapp/macAddress.sh";
     Process process = Runtime.getRuntime().exec(path);
     process.waitFor();

     BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
     StringBuffer sb = new StringBuffer();
     String line;
     while ((line = br.readLine()) != null){
         sb.append(line);
     }
     String str = sb.toString();
     return str;
 }

===============================================

测试:

 public static void main(String[] args) throws Exception {

     System.out.println("==========kaishi==========");
     String macAddress = getMACAddress();
     System.out.println("macAddress is: " + macAddress);

     String identifier = getIdentifier();
     System.out.println("identifier is: " + identifier);

     String uniquelyID = macAddress + "_" + identifier;
     System.out.println("uniquelyID is: " + uniquelyID);
     System.out.println("==========jieshu==========");

 }

===============================================

输出:

==========kaishi==========
macAddress is: **:**:**:**:**:**
identifier is: *x********
uniquelyID is: **:**:**:**:**:**_*x********
==========jieshu==========

使用java代码执行Linux命令:

1. 执行 "ifconfig" 命令

     private static String getMacAddress() throws Exception {
         String[] cmd = {"ifconfig"};

         Process process = Runtime.getRuntime().exec(cmd);
         process.waitFor();

         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
         StringBuffer sb = new StringBuffer();
         String line;
         while ((line = br.readLine()) != null) {
             sb.append(line);
         }

         return str1;
     }

2. 执行 "fdisk -l" 命令

     private static String getIdentifier() throws Exception {
         String[] cmd = {"fdisk", "-l"};

         Process process = Runtime.getRuntime().exec(cmd);
         process.waitFor();

         BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
         StringBuffer sb = new StringBuffer();
         String line;
         while ((line = br.readLine()) != null) {
             sb.append(line);
         }

         String str1 = sb.toString();

         return str1;
     }
