PowerShell自定義函數的參數沒有具體的命名規則，那么怎么做才能讓參數的命名更加科學可持續。

我們應該怎么來命名函數的參數名稱呢？有沒有一個可供參考的列表？當然微軟沒有給出來。但是我們可以來理一個列表出來。微軟自帶了大量的cmdlet，這些cmdlet使用的參數有什么規律呢？我們用下面一段命令來統計一下。

復制代碼代碼如下:

Get-Command -CommandType Cmdlet |
ForEach-Object { $_.Parameters } |
ForEach-Object { $_.Keys } |
Group-Object -NoElement |
Sort-Object Count, Name -Descending |
Select-Object -Skip 11 |
Where-Object { $_.Count -gt 1 }

這段代碼的作用就是把所有的cmdlet使用的參數名稱來做一個統計，看看哪些名稱的參數用得比較多，然后按從多到少的順序做一個列表。小編這邊運行后的結果如下：

復制代碼代碼如下:
