【目的】筛选出只有注册表项的行，筛选条件：行中没有逗号
【代码1】

type "C:\Users\Administrator\Desktop\要删除的趋势注册表信息\officescan.txt"|sed -n "/,/!p"
复制代码

【结果】正确，结果如下：

============
【代码2】

Setlocal enabledelayedexpansion
type "C:\Users\Administrator\Desktop\要删除的趋势注册表信息\officescan.txt"|sed -n "/,/!p"
复制代码

【结果】错误，结果把所有内容全部显示出来了
===========
【疑惑】为什么Setlocal enabledelayedexpansion会导致结果出错呢？根本原因在哪里？

WHY

开启变量延迟扩展以后，感叹符成为变量的引用符，未封闭的（单独的）感叹符在预处理时被丢弃
sed -n "/,/!p" 变成了 sed -n "/,/p"
把感叹符转义就好了，^!p

谢谢，已经解决
