这听起来像是一个糟糕的笑话，但显然来自 MS 的天才无法使超级复杂 - 排除 gci 参数工作。通过“天才”设计，它仅适用于文件，而不适用于整个路径。那么如何让它发挥作用。例如如何排除路径包含“Windows”子字符串的所有文件？天真
gci -exclude "*Windows*" -rec
不起作用

编辑：谷歌搜索/想通了这个：

 | where {$_.DirectoryName -notmatch ".*abcdef.*" }

如果有人知道更好的解决方案，请分享。如果没有，将关闭问题。

解决方案是这样的：

 gci ./ |Where{ $_.PSPath -notmatch ".*Windows.*"}

顺便说一句，对于猜测此类问题的解决方案很有用的是知道当前对象有哪些方法，为此我使用了 Get-Member。示例输出：

PS C:\Users\jh> gci ./ | Get-Member
