+# What is the SharePoint Online Management Shell?
 
 The SharePoint Online Management Shell is a Windows PowerShell module that you can use to manage SharePoint Online users, sites, and site collections. Command-line operations in Windows PowerShell are composed of a series of commands. Each command uses a cmdlet and a set of settings known as parameters. For example, you use the **New-SPOSite** cmdlet for a command that creates a new SharePoint Online site collection with a specified title, URL, owner, storage quota, and template (the parameters).
 
 SharePoint Online PowerShell commands can be very efficient for batch operations — for example, creating a dozen new site collections or adding hundreds of new SharePoint Online users to a site. For more information, see [Why you need to use Office 365 PowerShell](https://technet.microsoft.com/library/dn568034.aspx).

 The set of SharePoint Online Management Shell commands differs from the set of Office 365 for professionals and small businesses PowerShell commands. SharePoint Online Management Shell commands manage SharePoint Online users and site collections, whereas Office 365 commands manage Office 365-level tasks such as users, licenses, organization information, and services. They both manage users and groups. However, Office 365 PowerShell commands manage users and groups for all of the Office 365 services. The  SharePoint Online commands manage users and groups only for SharePoint Online.
