    public static void main(String[] args) {

        try {
            Process pro = Runtime.getRuntime().exec("/Users/hdwang/test.sh");
            InputStream in = pro.getInputStream();
            BufferedReader read = new BufferedReader(new InputStreamReader(in));
            String line = null;
            while((line = read.readLine())!=null){
                System.out.println(line);
            }

            pro.waitFor();

        } catch (Exception e) {
            e.printStackTrace();
