function GetHelp() {

$HelpText = @"

$HelpText

[system.enum]::getnames([System.Security.AccessControl.FileSystemRights])

}

function CreateFolder ([string]$Path) {

    # Check if the folder Exists

    if (Test-Path $Path) {
        Write-Host "Folder: $Path Already Exists" -ForeGroundColor Yellow
    } else {
        Write-Host "Creating $Path" -Foregroundcolor Green
        New-Item -Path $Path -type directory | Out-Null
    }
}

function SetAcl ([string]$Path, [string]$Access, [string]$Permission) {

    # Get ACL on FOlder

    $GetACL = Get-Acl $Path

    # Set up AccessRule

    $Allinherit = [system.security.accesscontrol.InheritanceFlags]"ContainerInherit, ObjectInherit"
    $Allpropagation = [system.security.accesscontrol.PropagationFlags]"None"
    $AccessRule = New-Object system.security.AccessControl.FileSystemAccessRule($Access, $Permission, $AllInherit, $Allpropagation, "Allow")

    # Check if Access Already Exists

    if ($GetACL.Access | Where { $_.IdentityReference -eq $Access}) {

        Write-Host "Modifying Permissions For: $Access" -ForeGroundColor Yellow

        $AccessModification = New-Object system.security.AccessControl.AccessControlModification
        $AccessModification.value__ = 2
        $Modification = $False
        $GetACL.ModifyAccessRule($AccessModification, $AccessRule, [ref]$Modification) | Out-Null
    } else {

        Write-Host "Adding Permission: $Permission For: $Access"

        $GetACL.AddAccessRule($AccessRule)
    }

    Set-Acl -aclobject $GetACL -Path $Path

    Write-Host "Permission: $Permission Set For: $Access" -ForeGroundColor Green
}

if ($help) { GetHelp }

if ($Path -AND $Access -AND $Permission) { 
    CreateFolder $Path 
    SetAcl $Path $Access $Permission
}

To run this script I use this command. ./SetFolderPermission.ps1 -Path E:\TestFolder\UsernameX -Access Domain\UsernameX -Permission modify

How can I make it so that i can just use one command and call it to create the folders from a CSV file?
