java執行系統命令

之前一直在用

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

後來發現有的時候好像不那麼好用，嘗試使用下面的方式感覺更好用一些。

import java.io.*;

public class ProcessTest {

    public static void main(String[] args) {
        String[] command1 = new String[]{"/bin/sh", "-c", "ls -l /tmp"};
        test1(command1);
    }

    public static void test1(String[] cmd) {
        try {
            ProcessBuilder builder = new ProcessBuilder(cmd);
            Process process = builder.start();
            InputStream is = process.getInputStream();
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String content = br.readLine();
            while (content != null) {
                System.out.println(content);
                content = br.readLine();
            }
            System.out.println(content);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}
