Write-Output inside Invoke-Command scriptblock - powershell

Question

Below is a script I'm working on to get all SQL-jobs into a CSV-file.
The script itself is working great but I have trouble with the error-handling.
I can't figure out how to get the Out-File inside the Catch-block to print to the file on my local machine instead of the remote machine I'm running the Invoke-Command to.
How do I accomplish this?
Thanks
PS. The script is written out fully as much as possible for non experienced co-workers convenience
$sqlServers = #("TEST1","TEST2")
$filePath = [Environment]::GetFolderPath("Desktop")
$dateToday = Get-Date -Format “yyMMdd HH:mm"
$dateTodayFile = Get-Date -Format “yyMMdd"
Write-Output "$dateToday $sqlServers" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append
$output = Invoke-Command -ComputerName $sqlServers -ScriptBlock{
Try
{
Import-Module sqlserver -ErrorAction Stop
}
Catch
{
Write-Output "$dateToday ERROR $env:computername" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append
Exit
}
$instances = $env:computername | Foreach-Object {Get-ChildItem -Path "SQLSERVER:\SQL\$_"}
ForEach ($instance in $instances){
Try
{
$instanceName = $instance.InstanceName
Get-SqlAgentJob -ServerInstance "$env:computername\$instanceName" -ErrorAction Stop |
Where-Object {$_.IsEnabled -eq "True" -and $_.LastRunDate -gt [DateTime]::Today.AddDays(-2) -and $_.OwnerLoginName -match "TEST"} |
Select-Object #{Name=‘Job name‘;Expression={$_.Name}},
#{Name=‘Description‘;Expression={$_.Description}},
#{Name=‘Instance‘;Expression={$_.Parent -Replace '[][]'}},
#{Name=‘Run outcome‘;Expression={$_.LastRunOutcome}},
#{Name=‘Run date‘;Expression={$_.LastRunDate}},
#{Name=‘Run duration‘;Expression={$_.LastRunDuration}},
#{Name=‘Job creator‘;Expression={$_.OwnerLoginName}},
#{Name=‘Runs on a schedule‘;Expression={$_.HasSchedule}},
#{Name='Schedule Type';Expression={$_.JobSchedules -join ','}}
}
Catch
{
Write-Output "$dateToday ERROR $env:computername\$instanceName" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append
Exit
}
}
}
$output | Select-Object -Property * -ExcludeProperty PSComputerName,RunSpaceID,PSShowComputerName |
Sort-Object "Job name" |
Export-Csv $filePath\SQLJobInvent$dateTodayFile.csv -NoTypeInformation -Delimiter ";" -Encoding UTF8
Write-Output "$dateToday $filePath" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append
Write-Output "----------------------------------------" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append

Your primary issue is scope.
The $dateToday, $filePath and $dateTodayFile are all declared on the local machine, but you're trying to use them on the remote computer (script block) where they are undefined.
There are a few ways to get your variables passed to the remote computer, below are two:
# Add desired variable to ArgumentList and define it as a parameter
Invoke-Command -ComputerName $sqlServers -ArgumentList $dateToday,$filePath,$dateTodayFile -ScriptBlock {
param(
$folderPath,
$filePath,
$dateTodayFile
)
# Do something with our injected variables
Write-Output "$dateToday ERROR $env:computername" |
Out-File "$filePath\Log$dateTodayFile.txt" -Append
}
OR
# In PS ver >= 3.0 we can use 'using'
Invoke-Command -ComputerName $serverName -ScriptBlock {Write-Output $using:dateToday}
