解決方法圍繞設計破解Powershell gci -exclude

Question

這聽起來像一個壞笑話，但顯然來自MS的天才arent能夠使uber複雜 - 排除gci參數的工作。通過「genious」設計，它僅適用於文件，而不是整個路徑。所以如何讓它工作。 例如如何排除路徑中包含「Windows」子字符串的所有文件？ 天真
gci -exclude "*Windows*" -rec
不工作

編輯：Google搜索/想通了這一點：

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

如果有人知道更好的解決方案，請分享。如果不會關閉問題。

Answer 1

解決的辦法是這樣的：

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

的猜測解決這樣的問題BTW有用的東西是要知道什麼樣的方法當前對象有，對於我用獲取會員。示例輸出：

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