一、Runtime.getRuntime().exec()執行命令情況：
       Runtime.getRuntime().exec("cmd /c your command")//2000
       Runtime.getRuntime().exec("command /c your command")//98
       Runtime.getRuntime().exec("sh/ your command")//linux

二、執行.sh檔案的情況：
      1、把命令寫成a.sh ；執行命令的時候
           Process child = Runtime.getRuntime().exec("bash a.sh,null,new File("//usr/local/mysql/bin/"));
           child.waitFor();
           ........
       2、Process child = Runtime.getRuntime().

                                          exec(new String[] {"/bin/sh","-c","mysqldump -u root -p7788919 axtic_cg" },

                                                   null,
                                                   new File("/usr/local/mysql/bin/"));
            child.waitFor();

            註：waitFor()等待操作完成
