我有一个包含以下形式数据的文件：

我想以这种方式退出： 日期、Hour_Start、Hour_End、Windows_APP
例如：
7/26/2018,12:15:51.512,12:52:48.681,LARTVERT31RT3111C
7/26/2018,14:00:51.512,14:52:48.681,LAPEVEBIOMBIOM03C
7/26/2018,15:00:51.512,15:22:48.681,LAPEVEPE27PE2701C
7/26/2018,15:00:51.512,15:22:48.681,LARTVEIT29IT2901C
我停在这里，因为他们开始重复 LAPEVEPE27PE2701C、LAPEVEBIOMBIOM03C、LARTVERT31RT3111C 和 LAESVEES03ES0301C（从这里开始）
包含此数据的文件大约重 3.5Mb。而且有很多行
有人可以帮助我如何使用 awk 或类似工具（perl 或 bash）进行操作

抱歉，这不是 StackOverflow 的工作方式。 “我想做 X，请给我提示和/或示例代码”形式的问题被认为是题外话。请访问help center并阅读How to Ask，尤其是阅读Why is “Can someone help me?” not an actual question?

grymoire.com/Unix/Awk.html 是学习 awk 和做文本处理的好地方..
