Delete a list of User Profiles - powershell

Question

(I am a newbie to PS who has mostly used VBS and Batch so I am still working on following PS scripts)
I need to delete most (but not all) domain accounts off of all 500 of our systems.
Some of these are from a specific list.
Some follow a generic format *21, *19, etc...
I can find scripts that will let me delete a specific user account but I can't figure out how to pass it the long list or use the wildcards...
This one seems promising if I can figure out how to get the values need in it...
:: This Script taken from https://www.nextofwindows.com/delete-user-profiles-on-a-remote-computer-in-powershell
$Computer = Read-Host "Please Enter Computer Name: "
$user = Read-Host "Enter User ID: "
Invoke-Command -ComputerName $computer -ScriptBlock {
param($user)
$localpath = 'c:\users\' + $user
Get-WmiObject -Class Win32_UserProfile | Where-Object {$_.LocalPath -eq $localpath} |
Remove-WmiObject
} -ArgumentList $user

It sounds like you are most of the way there. Just use some pipelines and a foreach loop or two.
This will attempt to remove all users in the list from all computers in the list:
# define function that takes user list from pipeline
function Remove-User {
[cmdletBinding()]
param(
[Parameter(ValueFromPipeline=$true,Mandatory=$true)]
[string]
$user,
[Parameter(Mandatory=$true)]
[string]
$computer
)
process {
# copied from question
Invoke-Command -ComputerName $computer -ScriptBlock {
Get-WmiObject -Class Win32_UserProfile |
Where-Object { $_.LocalPath -eq "c:\users\${$user}" } |
Remove-WmiObject
} -ArgumentList $user
}
}
# get your lists whatever way makes sense
$userList = Import-Csv -Path "users.csv" -Delimiter ','
$computerList = Import-Csv -Path "computers.csv" -Delimiter ','
# call function to remove all users for each computer
$computerList | ForEach-Object {
$userList | Remove-User -computer $_
}
I'm not sure where you get your list from, but I used a csv just because.
*note: This is going off the assumption that the Invoke-Command portion of code from nextOfWindows does what it says
