        try {
            process = Runtime.getRuntime().exec(cmd);
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line = null;
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(new String(line.getBytes(),"GBK"));

        String osName = props.getProperty("os.name"); // Operating system name 
        if(osName.toLowerCase().contains("linux")){
            return "/bin/sh -c";
        }else if(osName.toLowerCase().contains("windows")){
            return "cmd /c";
