bulk update extension attribute in AD

New Contributor
I have written below script to update the extension attribute and after updating I want the report in CSV. If I run till update it is working fine but when I am adding select-object to take the entries in CSV it is throwing an error.
Import-Csv -path c:\temp\SetExtAtt1.csv |ForEach-Object {
Set-ADComputer $_.samAccountName -replace @{
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"|Select-Object @{Label = "Name";Expression = {$_.samAccountName}},
@{Label = "Attribute4";Expression = {$_.extensionAttribute4}},
@{Label = "Attribute6";Expression = {$_.extensionAttribute6}}|Export-Csv C:\Temp\OwnerTest2.csv -Append -NoTypeInformation
}
}

To Export the Hash table you will need to use the GetEnumerator()

https://tommymaynard.com/hash-table-to-csv-2018/

I recommend that you replace the hash table with PSObject

I have made the below changes but each iteration of foreach loop saves to $Output. It overwriting what was there previously, i.e., the previous iteration. Which means that only the very last iteration is saved to $Output and exported.

 

Import-Csv -path c:\temp\SetExtAtt1.csv |ForEach-Object {
$Output = @()
Set-ADComputer $_.samAccountName -replace @{
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"}
$Output =New-Object -TypeName PSObject -Property @{
samAccountName = "$($_.samAccountName)"
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"
}
}
$Output | Export-Csv C:\Temp\OwnerTest2.csv -NoTypeInformation -Encoding UTF8 -Append

Yes, sure as the $Output=@() is inside the loop and is being reset everytime, a very quick fix will be to add a new variable at the top

and once the $output have the result, add it to the variable

try the code below and get the result from $allresult variable.

$allresult=@()
Import-Csv -path C:\123\EXDB1.csv |ForEach-Object {
$Output = @()
Set-ADComputer $_.samAccountName -replace @{
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"}
$Output =New-Object -TypeName PSObject -Property @{
samAccountName = "$($_.samAccountName)"
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"
$allresult=$output
}
}
$Output | Export-Csv C:\Temp\OwnerTest2.csv -NoTypeInformation -Encoding UTF8 -Append

Still last iteration is saved to $Output and exported, I am not getting all the results.

@Sushantjha 

Yes, becuase I forget to update the last line, as the CSV exporting the output not the $allreasult.

Check the updated

 

 

$allresult=@()
Import-Csv -path C:\123\EXDB1.csv |ForEach-Object {
$Output = @()
Set-ADComputer $_.samAccountName -replace @{
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"}
$Output =New-Object -TypeName PSObject -Property @{
samAccountName = "$($_.samAccountName)"
ExtensionAttribute4 = "$($_.ExtensionAttribute4)"
ExtensionAttribute6 = "$($_.ExtensionAttribute6)"
}
$allresult+=$output
}
$allresult | Export-Csv C:\Temp\OwnerTest2.csv -NoTypeInformation -Encoding UTF8 -Append
