Powershell Tips Series Part 1 : Script to get Sile collection details and sites with unique permission in SharePoint Online

As of now, I am more and more involved into automation of regular SharePoint activities into PowerShell scripts. Not all things are that easy to find out in MSDN and technet. I would be sharing scripts to the community through this series that would make the life easier to keep track of the scripts that would be essential for SharePoint development and administration activities

Script to fetch all the site collection details in SharePoint online

 Import-Module Microsoft.Online.SharePoint.PowerShell -DisableNameChecking -ErrorAction SilentlyContinue
 
 Connect-SPOService -Url "https://XXXX-admin.sharepoint.com" -Credential userid@example.com
 
 Get-SPOSite –Detailed | Export-CSV –LiteralPath “Path/filename.csv” –NoTypeInformation
