使用Powershell将计算机从csv文件移动到正确的OU

Question

Keep getting "Move-ADObject : Cannot validate argument on parameter 'TargetPath'. The argument is null or empty." when trying to move computers to their respective OU.

Tried these set of codes to achieve it but it doesn't work:

PS C:\temp> cat .\OUs.csv
OUName,Server
AD-DNS,AD-DNS-Server
Apps,App-Server
DBs,DB-Server1
DBs,DB-Server2
Utilities-Servers,Utils-Server
PS C:\temp>
PS C:\temp> $CSVFile = Import-Csv ".\OUs.csv"
PS C:\temp> foreach ($item in $CSVFile){
>> $computer = (Get-ADComputer $item.Server).DistinguishedName
>> $targetOU = (Get-ADOrganizationalUnit -filter "name -eq '$item.OUName'")
>>     Move-ADObject -Identity $computer -TargetPath $targetOU.DistinguishedName -Confirm:$false
>>     Write-Host "Computer $computer has been moved successfully to $targetOU"
>> }

But if I change

$targetOU = (Get-ADOrganizationalUnit -filter "name -eq '$item.OUName'")

to a specific OU, like this:

$targetOU = (Get-ADOrganizationalUnit -filter "name -eq 'AD-DNS'")

all the computers go to AD-DNS OU. Here's a session capture when I executed the code:

PS C:\temp>
PS C:\temp> cat .\OUs.csv
OUName,Server
AD-DNS,AD-DNS-Server
Apps,App-Server
DBs,DB-Server1
DBs,DB-Server2
Utilities-Servers,Utils-Server
PS C:\temp>
PS C:\temp> $CSVFile = Import-Csv ".\OUs.csv"
PS C:\temp> foreach ($item in $CSVFile){
>> $computer = (Get-ADComputer $item.Server).DistinguishedName
>> $targetOU = (Get-ADOrganizationalUnit -filter "name -eq '$item.OUName'")
>>     Move-ADObject -Identity $computer -TargetPath $targetOU.DistinguishedName -Confirm:$false
>>     Write-Host "Computer $computer has been moved successfully to $targetOU"
>> }

Expectation is that Server should get moved to it's corresponding OU .

Appreciate your help! Thank you.

Update1: I tried changing the code to the following:

$CSVFile = Import-Csv ".\OUs.csv"
foreach ($item in $CSVFile){
$computer = (Get-ADComputer $item.Server).DistinguishedName
$targetOU = (Get-ADOrganizationalUnit -filter "name -eq '$item.OUName'").DistinguishedName
    Move-ADObject -Identity $computer -TargetPath $targetOU -Confirm:$false
    Write-Host "Computer $computer has been moved successfully to $targetOU"
}

still got the same error.

Update 2: This works:

$CSVFile = Import-Csv ".\OUs.csv"
foreach ($item in $CSVFile){
    $computer = (Get-ADComputer $item.Server).DistinguishedName
    $targetOU = Get-ADObject -Filter "Name -eq '$($item.OUName)'"
    Move-ADObject -Identity $computer -TargetPath $targetOU.DistinguishedName -Confirm:$false
    Write-Host "Computer $computer has been moved successfully to $targetOU"
}

Answer 1

When accessing a property in a variable inside a quoted string, you have to escape it with $(...) to have it evaluated as an expression . So your code becomes:

$targetOU = (Get-ADOrganizationalUnit -filter "name -eq '$($item.OUName)'")
