PowerShell 如何抑制错误消息

Question

每当我运行 Update-Help 时，都会出现大量错误。 我已经放弃尝试解决这些问题，这就是 PowerShell 的工作方式，一些帮助文件定义总是无法更新（但如果有人知道如何解决这些问题，我会很感兴趣尝试）。

所以，我想抑制每个月更新这些东西的脚本中的错误。

我试过Update-Help -EA silent和Update-Help -EA silent | Out-Null Update-Help -EA silent | Out-Null但在这两种情况下，错误消息仍然以红色喷洒在屏幕上。

有谁知道热压制这些？

Answer 1

这将帮助您：

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

不要忘记存在WarningAction 。

我不确定它是否适用于您，但我试图抑制 Checkpoint-Computer 的“SystemRestorePointCreationFrequency”输出，这是一个警告——而不是一个错误。 以下将抑制该警告：

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