Manipulating windows ACL with PowerShell

[YourSurrogateGod]

Hey guys, long time no post, since like 2009

Anyways, here's my question. Sorry if this is the wrong forum, I had no idea where else to post it.

I have a file full of last-names separated by commas and then first-names.
Smith,Bob
Chicken,Ronald
Car,Anastasia

gc permissions.csv|% {$_.split(",")[0]}

I'd like to grab the first character of the first name and then pre-pend it to the string of the last name. The general idea is to find the user ID that's stored in Active Directory, in my company it's the first letter of the first name and then the last name.

Then I'm trying to add these users as read-only on a specific directory. Thoughts?

Do you have the AD plug-in? It makes it easier
