Powershell - Export-CSV and Append

Question

I have a script such as the following:

$in_file = \"C:\\Data\\Need-Info.csv\"
$out_file = \"C:\\Data\\Need-Info_Updated.csv\"
$list = Import-Csv $in_file 
Fo         


        

Answer 1

Convert the foreach loop into a foreach-object and move the export-csv to outside the outter foreach object so that you can pipe all the objects to the export-csv.

Something like this (untested):

$list | ForEach {
$zID = $_.zID
ForEach-Object { Get-QADUser -Service 'domain.local' -SearchRoot 'OU=Users,DC=domain,DC=local' -SizeLimit 75000 -LdapFilter "(&(objectCategory=person)(objectClass=user)(PersonzID=$zID))" |
Select-Object DisplayName,samAccountName,@{Name="zID";expression={$zID}} | 

}
} |Export-Csv $out_file -NoTypeInformation -Force
