Test-Path : Zugriff verweigert In K:\access\access.ps1:15 Zeichen:6 + If ((Test-Path $Db) -eq $false) { + ~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (K:\ss.mdb:String) [Test-Path], UnauthorizedAccessException + FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.TestPathCommand |
Answer:
Somewhat confusingly Test-Path actually generates an error in a number of cases. Set the standard ErrorAction parameter to SilentlyContinue to ignore it.
