Vista - Pipe Yes or No to cmdlet

I am trying to schedule via windows scheduler the execution of the following
script:

-------------------Begin SCRIPT-------------------
param ([string] $DPMServerName, [string] $LibraryName)

if (!(Get-PSSnapin microsoft.dataprotectionmanager.powershell))
{write-host "Adding PS Snapin for DPM..." -Fore Green
add-PSSnapin Microsoft.DataProtectionManager.PowerShell}

if(("-?","-help") -contains $args[0])
{
Write-Host "Usage: UnlockLibrary.ps1 [[-DPMServerName] <Name of the DPM
server>] [-LibraryName] <Name of the library>"
Write-Host "Example: UnlockLibrary.ps1 -DPMServerName
MyDPMServer.domain.local -LibraryName "My library""
exit 0
}

if (!$DPMServerName)
{
$DPMServerName = Read-Host "DPM server name: "
if (!$DPMServerName)
{
Write-Error "Dpm server name not specified."
exit 1
}
}

if (!$LibraryName)
{
$LibraryName = Read-Host "Library name: "
if (!$LibraryName)
{
Write-Error "Library name not specified."
exit 1
}
}

if (!(Connect-DPMServer $DPMServerName))
{
Write-Error "Failed to connect To DPM server $DPMServerName"
exit 1
}

$library = Get-DPMLibrary $DPMServerName | where {$_.UserFriendlyName -eq
$LibraryName}

if (!$library)
{
Write-Error "Failed to find library with user friendly name $LibraryName"
exit 1
}

Unlock-DPMLibraryDoor -DPMLibrary $library

-------------------END SCRIPT-------------------

The problem is Unlock-DPMLibraryDoor prompts for a Yes or No to continue and
MS DPM Team has not provided a parameter to specify this. How can I
effectively echo the response to the console like you would in a dos cmd
(echo Y | Unlock-DPM....)

Any help would be greatly appreaciated.

done their homework. I don't have the snapin to try it out myself.

Unlock-DPMLibraryDoor -DPMLibrary $library -Confirm:$false

Let us know how it goes. If this does not work, we really need to push back to
that team so that they implement this common powershell convention.

Hi Hal,

Thanks for your response. Unfortunately the DPM team has not included the
common convention and does not work.

Perhaps Marco's link will help in the meantime.
