Enumerate all event receivers attached to Sharepoint list via PowerShell

Sometimes we need to enumerate all event receivers attached to specific Sharepoint list. The simplest way to do that is to use PowerShell. The following PowerShell script shows all event receivers attached to specified list:

param( 
    [string]$url,
    [string]$listName
)

$web = Get-SPWeb $url
$list = $web.Lists[$listName]

foreach($eventReceiverDef in $list.EventReceivers)
{
    $eventInfo = $eventReceiverDef.Class + ", " + $eventReceiverDef.Assembly + " – " + $eventReceiverDef.Type
    Write-Host $eventInfo -ForegroundColor green
}

In order to run it specify url of the web site which contains the list and list title:

check.ps1 http://example.com MyList

Here is example of running this script for standard Discussino board list:
