PowerShell Function To Add Filesystem Permissions

Recently wrote a simple function to add permission to filesystem resources. It defaults to modify permissions, but can also be another basic permission for instance: Read, Write or FullControl.

function fnAddFilesystemPermissions()
{
  param (
    [string]$sPath,
	[string]$sUserName,
	[string]$sPermission = "Modify"
  )

  # Add write permissions to a file using powershell...
  $accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule($sUserName,$sPermission,"Allow")
  $acl = Get-ACL -Path $sPath
  $acl.SetAccessRule($accessRule)
  $acl | Set-Acl -Path $sPath

  # Return permissions...
  return (Get-ACL -Path $sPath).Access | Format-Table 
}

PS> fnAddFilesystemPermissions -sPath “C:\Path\To\Resource” -sUserName “User-Principle-Name” [-sPermission “FullControl“]
