Get SharePoint Central Admin URL in PowerShell
In PowerShell script writing, I had to get the 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
