SharePoint 2010 + PowerShell: Delete Site Content Type

So first, you have to delete all of the content type’s children or you’ll receive the error “Error: content type in use.” Once the dependencies are gone, you can delete the custom site content type itself.

$sitename = $args[0]
$contentType = $args[1]

$web = Get-SPWeb $sitename
$ct = $web.ContentTypes[$contentType]

if ($ct) {
$ctusage = [Microsoft.SharePoint.SPContentTypeUsage]::GetUsages($ct)
      foreach ($ctuse in $ctusage) {
        $list = $web.GetList($ctuse.Url)
        $contentTypeCollection = $list.ContentTypes;
        Write-host "Deleted $contentType content type from $ctuse.Url"
Write-host "Deleted $contentType from site."

} else { Write-host "Nothing to delete." }

    @ Jesse: You can also "hard code" the name of your site, instead of passing it as an argument.
    There are also other ways to retrieve the site you want, which is well documented.
    The more important coding parts in this post, is after the retrieval of the site.
