            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();
