How to Remove a Quick Launch Item using PowerShell

I was recently asked to remove a Quick Launch item in all quick launch menus across an entire web application.  The following PowerShell will iterate over all webs in all sites in a web application searching for the menu item labelled “BAD Quick Launch Item” and will delete that node from each location.

$FindString = “BAD Quick Launch Item”

Get-SPWebApplication “http://webapplication.company.com” | Get-SPSite -Limit ALL | Get-SPWeb -Limit ALL | ForEach-Object {
    $web = $_
    $_.Navigation.QuickLaunch | ForEach-Object {
        $_.Children | ForEach-Object {
            if($_.title -eq $FindString){
                $node = $_
                $node.delete()
                Write-Host “Deleted node from ” $web “-” $web.url
            }
        }
    }
}

Hopefully this helps anyone else in the same situation.
