 #### 第二步： 运行你的批处理脚本
 
-通过`-b`开启批处理模式， `-f`执行脚本文件， 批处理脚本默认会输出到标准输出中，可以将结果重定向到文件中。

 * Commands such as `watch`/`tt`/`trace`/`monitor`/`stack` should include `-n` option to ensure the script can be able to quit.
 * Also consider to use `async` (for example: `watch c.t.X test returnObj > &`) to put commands run at background and get the output from the log file, see more from [asynchronous job](async.md)
 
 #### Step 2: Run the script
 
-Use `-b` to turn on batch mode, and use `-f` to specify the script file. By default the result will be output to the standard output, but you can redirect the output to the file like this:
