Get-ADuser并导出到多个CSV文件

Question

I'm using the following command to grab users from an OU and export to csv file:

Get-ADUser -Filter * -SearchBase 'OU=Contoso Users,OU=Contoso,DC=domain,DC=local' -Properties * | Select UserPrincipalName, EmailAddress | Sort UserPrincipalName | Export-CSV $UsersToMigrate -NoTypeInformation -Force

Is there anyway to export to multiple csv files of 10 users per file?

Answer 1

Append to the respective output file in a loop and use a counter and integer division to determine the actual filename.

$i = 0
... | Sort UserPrincipalName | ForEach-Object {
    $csv = "C:\path\to\output_$([Math]::Floor([int]$i/[int]10)).csv"
    $_ | Export-Csv $csv -NoType -Append
    $i++
}

Answer 2

$Users = Get-ADUser -Filter * -SearchBase 'OU=Contoso Users,OU=Contoso,DC=domain,DC=local' -Properties * | Select UserPrincipalName, EmailAddress | Sort UserPrincipalName
$Users | ForEach-Object -Begin {$i = 1} {
     $_ | Export-CSV "$UsersToMigrate-$([Math]::Ceiling($i++ / 10)).csv" -NoTypeInformation -Append
}

Explanation

• Iterates through the collection of users with ForEach-Object , initialising a counter variable $i as 1 in a Begin block first.
• Divides the counter by 10 and rounds up to the nearest integer. Uses this as part of the CSV name and exports to the CSV with the -Append switch (requires PSv3+ I believe).
