Microsoft’s command-line interface, PowerShell, has seen a surge of popularity in recent years. This is due to its ease of use and cross platform compatibility with Windows/Linux/MacOS platforms. In this blog post we will give an overview on the basics of PowerShell commands and go over some common examples to get you started!.

The “powershell group-object multiple properties” is a command that allows you to view the membership of a group.

Understanding the PowerShell Group Object Command

When working with PowerShell, you’ll sometimes need to interact with data sets. We deal with a large number of data, user accounts, virtual computers, and other things. When you show these different things in the console, they will scroll down the screen one by one, regardless of how you want them to appear. But it’s something that can be fixed! You may group items together using the PowerShell Group-Object cmdlet. This cmdlet works in the same way as the SQL GROUP BY command.

The Powershell Group Object cmdlet allows you to summarize items based on their attributes. This cmdlet gives the scripter a bird’s eye view of several object attributes in groups at once.

Let’s make a number of objects that are of the same kind. Any sort of object may be used. However, I’ll utilize System.ServiceProcess in this example. The Get-Service cmdlet returns ServiceController objects.

Make sure you’re only grouping items of the same type for Group-Object to behave properly. It’s critical that all items have the same characteristics.

PS51> $services = Get-Service PS51> $services Status Name DisplayName —— —- ———– Stopped AdtAgent Microsoft Monitoring Agent Audit Fo… Stopped AJRouter AllJoyn Router Service Stopped ALG Application Layer Gateway Service –snip–

There are no parameters in a group-object.

All services on my local computer are returned by Get-Service. Because there are so many services here, I can’t tell you their status, startup type, or anything else. I’d want to categorize these services based on their current condition. I’ll pipe all service objects to PowerShell’s Group-Object cmdlet and utilize the Status attribute to group these services.

PS51> $services | Group-Object Count Name Group —– —- —– 272 AdtAgent {AdtAgent, AJRouter, ALG, AppHostSvc…}

You may acquire the count by feeding all services to a Powershell Group Object. It’s a big thing, but it’s also beneficial.

Organizing things based on a single characteristic

To group them by a certain attribute (in this example, status), I must inform Group-Object that I want to group them by that property. The Property argument on Group-Object is used to do this.

PS51> $services | Group-Object -Property Status Count Name Grou —– —- —– 160 Stopped {AdtAgent, AJRouter, ALG, AppIDSvc…} 112 Running {AppHostSvc, Appinfo, Appveyor.Server, AudioEndpointBuilder…}

Now we’re having a conversation! I can now check how many services are started and halted at the same time. I’m sure I can do the same for StartType.

PS51> $services | Group-Object -Property StartType Count Name Group —– —- —– 9 Disabled {AdtAgent, AppVClient, NetTcpPortSharing, RemoteAccess…} 184 Manual {AJRouter, ALG, AppIDSvc, Appinfo…} 79 Automatic {AppHostSvc, Appveyor.Server, AudioEndpointBuilder, Audiosrv…}

Filtering Output from Group-Objects

Perhaps I’d want to go further and see the real services provided by one or more of these organizations. These items may be found by inspecting the Group property supplied by the Powershell group object command. All of the services with the grouped by object attribute value are stored in the Group object. If I’m grouping based on service status, I can filter the services by the status of Stopped and then expand the Group object to see all of the stopped services.

PS51> $services | Group-Object -Property Status | Where {$_.Name -eq ‘Stopped’} | Select -ExpandProperty Group Status Name DisplayName —— —- ———– Stopped AdtAgent Microsoft Monitoring Agent Audit Fo… Stopped AJRouter AllJoyn Router Service Stopped ALG Application Layer Gateway Service Stopped AppIDSvc Application Identity Stopped AppMgmt Application Management Stopped AppReadiness App Readiness –snip–

Objects are grouped based on several attributes.

You may group items like this not just on a single property, but you can also group them on several properties. You may want to look at all of the services depending on their status and start type. To do so, I just need to add another property name to Group-Property Object’s argument.

PS51> $services | Group-Object -Property Status,StartType Count Name Group —– —- —– 9 Stopped, Disabled {AdtAgent, AppVClient, NetTcpPortSharing, RemoteAccess…} 145 Stopped, Manual {AJRouter, ALG, AppIDSvc, AppMgmt…} 73 Running, Automatic {AppHostSvc, Appveyor.Server, AudioEndpointBuilder, Audiosrv…} 39 Running, Manual {Appinfo, camsvc, CertPropSvc, ClipSVC…} 6 Stopped, Automatic {gpsvc, MapsBroker, sppsvc, TrustedInstaller…}

As you can see, by adding another property, you can effectively generate a lot of “and” situations and group them on as many properties as you need!

Summary

The Group-Object cmdlet allows you to group similar items together based on a shared attribute. Organizing items in this manner is useful in a variety of ways. I hope that by understanding how the Group-Object cmdlet works, you’ll be able to come up with new ways to enhance and develop better PowerShell scripts!

If you’re just starting started with PowerShell, I recommend taking a look at my PowerShell tool-building mini-course!

The “powershell group array of objects” is a command that allows users to list the members of a group. It can be used in conjunction with other commands, such as Get-ADGroupMember and Remove-ADGroupMember.

Frequently Asked Questions

What is group-object in PowerShell?

A: It is a type of object that has members that are accessible as an array. For example, the following script will list all groups on your computer:
List-Group -computers localhost

How do you use group objects?

A: In order to use group objects you have to select them. Theres a button on the left of the group that says select. Once its selected, move your controller over that object and press X or Circle if youre playing with an Xbox one or PlayStation 4 respectively. If youre using Beat Saber for PSVR then just move your tracker over the grouped object and hold down on trackpad A/B to activate it.
