 public static String excuteCommand(String command){
        Runtime runtime = Runtime.getRuntime();
        try {
            Process process = runtime.exec(command);
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream(), Charset.forName("GBK")));
            StringBuffer sb = new StringBuffer();
            String inline;
            while(null != (inline = bufferedReader.readLine())){
                sb.append(inline).append("\n");
            }
            return sb.toString();
        } catch (IOException e) {
            e.printStackTrace();
