Hi,
We utilize New-PSUSchedule in one of our workflows.
As sometimes - especially during testing / development - I have to run the workflow multiple times, it creates a lot of identical schedules.
In order to prevent this I put in the workflow a step to delete similarly named schedules. however the Remove-PSUSchedule commandlet does not seem to work.
To test this, I wrote a small function, and I can confirm deleting does not happen.
function Delete-PSUScheduleMatches {
[CmdletBinding(SupportsShouldProcess=$true, ConfirmImpact='High')]
param(
[Parameter(Mandatory=$false)]
[string]$ComputerName = 'localhost',
[Parameter(Mandatory=$true)]
[string]$AppToken,
[Parameter(Mandatory=$true)]
[string]$ScheduleNamePattern
)
Write-Verbose "Attempting to delete schedules matching '$ScheduleNamePattern' on $ComputerName."
try {
# Get the schedules that match the pattern
# The 'Where-Object' filters the *full* objects before piping
# to Remove-PSUSchedule.
$schedulesToDelete = Get-PSUSchedule -ComputerName $ComputerName -AppToken $AppToken `
| Where-Object { $_.Name -like $ScheduleNamePattern }
if ($null -ne $schedulesToDelete) {
Write-Verbose "Found $($schedulesToDelete.Count) schedule(s) matching '$ScheduleNamePattern'."
foreach ($schedule in $schedulesToDelete) {
if ($PSCmdlet.ShouldProcess("Schedule '$($schedule.Name)' (ID: $($schedule.Id))", "Delete schedule")) {
Write-Verbose "Deleting schedule: $($schedule.Name) (ID: $($schedule.Id))"
# Explicitly pass the ID of the schedule to Remove-PSUSchedule for direct deletion.
# This avoids potential issues with full object pipeline binding if the cmdlet doesn't support it directly.
Remove-PSUSchedule -Id $schedule.Id -Verbose -ComputerName $ComputerName -AppToken $AppToken -TrustCertificate
}
}
} else {
Write-Warning "No schedules found matching '$ScheduleNamePattern' on $ComputerName."
}
}
catch {
Write-Error "An error occurred during schedule deletion: $($_.Exception.Message)"
Write-Error "Error details: $($_.Exception | Format-List -Force | Out-String)"
}
finally {
Write-Verbose "Verifying remaining schedules matching '$ScheduleNamePattern'."
# Re-fetch and output the schedules to confirm deletion status
Get-PSUSchedule -ComputerName $ComputerName -AppToken $AppToken `
| Where-Object { $_.Name -like $ScheduleNamePattern } | Select-Object Name, Id
}
}
# Example Usage (Uncomment to run)
# Replace "YOUR_APP_TOKEN_HERE" with your actual PowerShell Universal App Token
# Delete-PSUScheduleMatches -AppToken "YOUR_APP_TOKEN_HERE" -ScheduleNamePattern "*gandalf*" -Confirm:$false
