Add Top Link Bar Inheritance using PowerShell for SharePoint 2010

I would like to kick off the New Year with perhaps my shortest blog entry for 2012!

I had a client that created several subsites without selecting to use the same navigation as its parent. The decision was later made to add this back in order to provide some consistency throughout the environment. To easily resolve this, open up the SharePoint 2010 Management Shell and perform the following:

For one site:

$web = Get-SPWeb -Identity http://portal.company.com

$web.Navigation.UseShared = $true

For every site in the Site Collection:

Get-SPSite -Identity http://portal.company.com | Get-SPWeb -Limit All | %{$_.Navigation.UseShared=$true}

Yes, it’s THAT simple!
