Powershell: Disable AD User from csv and append Description

The file should contain the samaccountnames and looks like:

user1
user2
user3

Script:

$logfile = "C:\admin\VacationUsers.csv"
get-content $logfile |get-aduser -Properties Description | ForEach-Object { Set-ADUser $_ -enabled $false -Description "$($_.Description) DISABLED as requested by HR" }

How it works:
- Define file path
- Just get the users from csv
- Use get-aduser to get description
- do this for each user and...
- Set description


We keep the old Description with $($_.Description) and all that follows will be appended. In my example it is DISABLED as requested by HR.
