Question

如果我使用ls命令在PowerShell中对磁盘进行完全递归搜索，并将ErrorAction设置为SilentlyContinue，当它遇到无法访问的文件夹时仍会发生炸弹。< / p>

我可以将呼叫包裹在try catch中，但这不会阻止搜索终止，它只会吞下错误。

示例：

ls -Include msdeploy.exe -Recurse -ErrorAction SilentlyContinue;

结果：

PS C:\> ls msdeploy.exe -Recurse -ErrorAction SilentlyContinue

我会尝试全局变量，我认为还有另一种方式。

Answer 1

尝试设置$ErrorActionPreference = "silentlycontinue"而不是使用参数-ErrorAction SilentlyContinue。很久以前有人提到-EA有时可能会起作用。

Answer 2

所以Ansgar能够使错误无声，但在脚本中错误有效地默默地停止了执行。

我无处可去，心情不好。

我今天早上回到RDP到Windows Server 2008 R2虚拟机并且看不到它已经从Windows Update运行重新启动了。更令人惊奇的是，这个问题神秘地消失了！

时机令人难以置信。这些是更新：

但是，应该注意的是，它可能是重新启动的行为（这是一个服务器），它可能已经取代了很久以前安装更新中待处理的DLL。

ls -Recurse -ErrorAction SilentlyContinue不起作用
