PowerShell 如何抑制錯誤消息

Question

每當我運行 Update-Help 時，都會出現大量錯誤。 我已經放棄嘗試解決這些問題，這就是 PowerShell 的工作方式，一些幫助文件定義總是無法更新（但如果有人知道如何解決這些問題，我會很感興趣嘗試）。

所以，我想抑制每個月更新這些東西的腳本中的錯誤。

我試過Update-Help -EA silent和Update-Help -EA silent | Out-Null Update-Help -EA silent | Out-Null但在這兩種情況下，錯誤消息仍然以紅色噴灑在屏幕上。

有誰知道熱壓制這些？

Answer 1

這將幫助您：

Update-Help -ErrorAction SilentlyContinue

或者

Try {
  Update-Help -ErrorAction Stop
  # Use this method only if you want to halt script on errors
}
Catch {
  # Place action on error here
}

Answer 2

不要忘記存在WarningAction 。

我不確定它是否適用於您，但我試圖抑制 Checkpoint-Computer 的“SystemRestorePointCreationFrequency”輸出，這是一個警告——而不是一個錯誤。 以下將抑制該警告：

Checkpoint-Computer -Description "my description" -RestorePointType "MODIFY_SETTINGS" -WarningAction SilentlyContinue
