Get SharePoint Central Admin URL in PowerShell

In a PowerShell script writing, I had to get central admin URL of the SharePoint farm. Tried various approaches and found the below to get SharePoint 2010/SharePoint 2013 Central Administration site URL using PowerShell:

#sharepoint 2010 powershell get central admin url
Get-SPWebApplication -includecentraladministration | where `
  {$_.IsAdministrationWebApplication} | Select -ExpandProperty URL

Alternatively,  you can use:

[Microsoft.SharePoint.Administration.SPAdministrationWebApplication]::Local.URL
