java中使用Process执行linux命令

代码如下

                   　　  BufferedReader reader = null;
                    　　 String cmd = "netstat -anp|grep :8080";//命令中有管道符 | 需要如下执行命令
                        Process process = Runtime.getRuntime().exec(new String[]{"sh", "-c", cmd});
                        reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
                        String line = null;
                        while ((line = reader.readLine()) != null) {
                            System.out.println("***   " + line);
                        }
