Write script to update extensionAttribute2 field multiple users

I need to write a script that will pull in a CSV list of AD users and update the extensionAttribute2 field for said users.  I know the basics and I'll need to use the set-aduser command but I'm not sure exactly how to do the rest.  Please help!

Hey there,
The procedure is quite simple:
 First, you need to import the csv into a variable , here we took "usercsv"   .
Second, we will provide filters as required and update fields respectively using Get and Set attribute commands :
Consider this example for deeper understanding -
#$userscsv = import-csv D:\home\test.csv            
$users = Import-Csv -Path D:\Scripts\test.csv            

foreach ($user in $users) {            
#Search in specified OU and Update existing attributes            
 Get-ADUser -Filter "SamAccountName -eq '$($user.samaccountname)'" -Properties * -SearchBase "cn=Users,DC=manticore,DC=org" |            
  Set-ADUser -City $($user.City) -Office $($user.Office) -Division $($user.Division)

I hope this resolves your query

Following code will do it..
Import-Csv C:\USER.CSV | %{
Set-ADUser -Identity $_.Name -replace @{extensionAttribute2="myValue"}

Open in new window

The solution you gave me works perfectly.  One additional question...how would I add a field to it?  If I wanted to update the Organization AD field with data in the second column of the CSV...is that possible?

Yes it is possible.. Please open a new question for additional requests.. :-)
