Without parameters, this cmdlet gets all of the processes on the local computer. You can also specify a particular process by process name or process ID PID or pass a process object through the pipeline to this cmdlet. By default, this cmdlet returns a process object that has detailed information about the process and supports methods that let you start and stop the process.
You can also use the parameters of the Get-Process cmdlet to get file version information for the program that runs in the process and to get the modules that the process loaded. This command gets a list of all active processes running on the local computer. For a definition of each column, see the Notes section. This command gets all available data about the Winword and Explorer processes on the computer.
It uses the Name parameter to specify the processes, but it omits the optional parameter name. You can also identify the processes by their process IDs. For instance, Get-Process -Id This command gets all processes that have a working set greater than 20 MB.
It uses the Get-Process cmdlet to get all running processes. The pipeline operator passes the process objects to the Where-Object cmdlet, which selects only the object with a value greater than 20, bytes for the WorkingSet property. WorkingSet is one of many properties of process objects. To see all of the properties, type Get-Process Get-Member. By default, the values of all amount properties are in bytes, even though the default display lists them in kilobytes and megabytes.
These commands list the processes on the computer in groups based on their priority class. This example provides a Format-Table command that adds the MachineName property to the standard Get-Process output display. This command uses the FileVersionInfo parameter to get the version information for the pwsh. To run this command with processes that you do not own on Windows Vista and later versions of Windows, you must open PowerShell with the Run as administrator option.
This command uses the Module parameter to get the modules that have been loaded by the process. This command gets the modules for the processes that have names that begin with SQL.
To run this command on Windows Vista and later versions of Windows with processes that you do not own, you must start PowerShell with the Run as administrator option.
This command shows how to find the owner of a process. You can use this method to distinguish the host process from other PowerShell processes that you might want to stop or close. This command gets all the processes that have a main window title, and it displays them in a table with the process ID and the process name.
The mainWindowTitle property is just one of many useful properties of the Process object that Get-Process returns. Indicates that this cmdlet gets the file version information for the program that runs in the process. On Windows Vista and later versions of Windows, you must open PowerShell with the Run as administrator option to use this parameter on processes that you do not own. To get file version information for a process on a remote computer, use the Invoke-Command cmdlet. Using this parameter is equivalent to getting the MainModule.
FileVersionInfo property of each process object.Sends the specified objects to the next command in the pipeline. If the command is the last command in the pipeline, the objects are displayed in the console. The Write-Output cmdlet sends the specified object down the pipeline to the next command. If the command is the last command in the pipeline, the object is displayed in the console.
Write-Output sends objects down the primary pipeline, also known as the "output stream" or the "success pipeline.
This cmdlet is typically used in scripts to display strings and other objects on the console. One of the built-in aliases for Write-Output is echo and similar to other shells that use echothe default behavior is to display the output at the end of a pipeline.
In PowerShell, it is generally not necessary to use the cmdlet in instances where the output is displayed by default. By default, Write-Output enumerates through collections provided to the cmdlet.
However, Write-Output can also be used to pass collections down the pipeline as a single object with the NoEnumerate parameter. This command pipes the "test output" string to the Get-Member cmdlet, which displays the members of the System. String class, demonstrating that the string was passed along the pipeline. This command adds the NoEnumerate parameter to treat a collection or array as a single object through the pipeline.
Specifies the objects to send down the pipeline. Enter a variable that contains the objects, or type a command or expression that gets the objects. By default, the Write-Output cmdlet always enumerates its output.
The NoEnumerate parameter suppresses the default behavior, and prevents Write-Output from enumerating output. The NoEnumerate parameter has no effect if the command is wrapped in parentheses, because the parentheses force enumeration. For example, Write-Output 1,2,3 still enumerates the array. This switch only works correctly with PowerShell Core 6. On older versions of PowerShell Core, the collection is still enumerated even with use of this switch. Skip to main content.

Using Get-Command on its own is admittedly not very useful as its just going to spit out every command that PowerShell has. But from this we can see that that objects that PowerShell outputs have both a Name and a ModuleName property.
Using this information we can fine grain our search, by searching for cmdlets that contain certain terms. As you can see we still get quite a few results, our next option is to search within a specific module. Once you have found the cmdlet you are looking for using Get-Command, you are going to want to know the syntax and how you can use that specific cmdlet. This is where Get-Help comes in, if you have ever used the command line in Windows you probably did something like this:.
So instead we use Get-Help and pass a cmdlets name to Get-Help as a parameter. Get-Member allows us to get information about the objects that a cmdlets returns.
The first problem is that, while those are the properties you might be looking for most of the time, there are still more of them.
To see the methods and properties we can pipe our output to Get-Member, like so:. While it may mean nothing to you right now, you will sooner or later need to use Get-Member, and the sooner you learn to use it the better.
As an example, using the information from the output we could do something like:. Start-Process notepad. WaitForExit Start-Process calc. While not exactly a cmdlet, it is one of the most used special variables in PowerShell.
It is used in script blocks, filters, the process clause of functions, where-object, foreach-object and switches. However it is easier to explain with an example, which brings us to our next and final cmdlet, Where-Object. Where-Object does exactly what it sounds like, it selects an object based on whether it meets a certain criteria.
To demonstrate this, we will pipe the output of Get-Process into the Where-Object cmdlet. The Best Tech Newsletter Anywhere.

How-To Geek is where you turn when you want experts to explain technology.The Get-Command cmdlet gets all commands that are installed on the computer, including cmdlets, aliases, functions, filters, scripts, and applications. Get-Command gets the commands from PowerShell modules and commands that were imported from other sessions. To get only commands that have been imported into the current session, use the ListImported parameter. Without parameters, Get-Command gets all of the cmdlets, functions, and aliases installed on the computer.
Get-Command that uses the exact name of the command, without wildcard characters, automatically imports the module that contains the command so that you can use the command immediately. Get-Command gets its data directly from the command code, unlike Get-Helpwhich gets its information from help topics.
Starting in Windows PowerShell 5. A new Version property has been added to the CommandInfo class. This command gets the PowerShell cmdlets, functions, and aliases that are installed on the computer. This command uses the ListImported parameter to get only the commands in the current session.
This command gets all of the cmdlets, sorts them alphabetically by the noun in the cmdlet name, and then displays them in noun-based groups.
This display can help you find the cmdlets for a task. This command uses the Module parameter to get the commands in the Microsoft. Security and Microsoft.
Utility modules. This command gets information about the Get-AppLockerPolicy cmdlet. It also imports the AppLocker module, which adds all of the commands in the AppLocker module to the current session.
When a module is imported automatically, the effect is the same as using the Import-Module cmdlet. The module can add commands, types and formatting files, and run scripts in the session. This command uses the ArgumentList and Syntax parameters to get the syntax of the Get-ChildItem cmdlet when it is used in the Cert: drive.
When you compare the syntax displayed in the output with the syntax that is displayed when you omit the Args ArgumentList parameter, you'll see that the Certificate provider adds a dynamic parameter, CodeSigningCertto the Get-ChildItem cmdlet.
The command in the example uses the Get-DynamicParameters function to get the dynamic parameters that the Certificate provider adds to the Get-ChildItem cmdlet when it is used in the Cert: drive. The Get-DynamicParameters function in this example gets the dynamic parameters of a cmdlet.
This is an alternative to the method used in the previous example. Dynamic parameter can be added to a cmdlet by another cmdlet or a provider. It returns an ApplicationInfo object System.
ApplicationInfo for each file, not a FileInfo object System. This command gets cmdlets that have a parameter whose name includes Auth and whose type is AuthenticationMechanism.By default each Azure PowerShell cmdlet formats output to be easy to read.
PowerShell allows you to convert or format cmdlet output by piping to one of the following cmdlets:. Formatting is used for display in a PowerShell terminal, and conversion is used for generating data to be consumed by other scripts or programs. By default, Azure PowerShell cmdlets output in the table format. This format doesn't display all information of the requested resource:.
The amount of data displayed by Format-Table can be affected by the width of your PowerShell session window. To restrict the output to specific properties and order them, property names can be provided as arguments to Format-Table :. List output format produces two columns, property names followed by the value. For complex objects, the type of the object is displayed instead. Wide output format produces only one property name per query.
Which property is displayed can be controlled by giving a property as an argument. The Custom-Format output type is meant for formatting custom objects. Without any arguments, it behaves like Format-List but displays the property names of custom classes. To get only some properties from the Azure PowerShell results, use the Select-Object command in a pipe before performing the conversion.
The following examples demonstrate the different kinds of output that each conversion produces. JSON output doesn't expand all properties by default. To change the depth of properties expanded, use the -Depth argument.
By default, the expansion depth is 2. Rendering of the HTML will depend on your browser behavior for rendering tables which contain no width information.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am trying a few things in Powershell and what I don't manage to achieve is the following in Exchange :. If anyone has an answer, I have searched the web but with no success as I've had difficulties explaining it in a few words. Create new object with properties from both objects.
I don't know if it is the best or optimal solution, but you certainly do it by saving actual user to variable in foreach:. The first step saving users into separate variable is required only when working with Exchange cmdlets - as mentioned hereyou cannot nest Exchange cmdlets in foreach This error is caused when executing the Exchange cmdlets through PowerShell remoting, which do not support more than one pipeline running at the same time.

You may see this error when you pipe the output from a cmdlet to foreach-object, which then runs another cmdlet within its scriptblock. I've had to add a specific field in input of Get-MailboxStatistics because remotely, I was having:.
For some reason the Identity parameter doesn't take pipelne input by value, only by property name. So in order to get it to work you can change the name of piped in data to match the parameter name of Identity. Then Get-MailboxStatistics finally knows how to treat the data your feeding it via the pipeline. Learn more.

Hi Shay, I'm having the same issue whith your code: Pipeline not executed because a pipeline is already executing. Pipelines cannot be executed concurrently. May 14 '12 at PowerShell has a set of cmdlets that allow you to control how properties are displayed for particular objects. The names of all the cmdlets begin with the verb Format.
They let you select which properties you want to show. Each object type in PowerShell has default properties that are used when you don't specify which properties to display. Each cmdlet also uses the same Property parameter to specify which properties you want to display. Because Format-Wide only shows a single property, its Property parameter only takes a single value, but the property parameters of Format-List and Format-Table accept a list of property names.
In this example, the default output of Get-Process cmdlet shows that we have two instances of Internet Explorer running. The Format-Wide cmdlet, by default, displays only the default property of an object. The information associated with each object is displayed in a single column:. With the Format-Wide cmdlet, you can only display a single property at a time.
This makes it useful for displaying large lists in multiple columns. The Format-List cmdlet displays an object in the form of a listing, with each property labeled and displayed on a separate line:. The Format-List cmdlet lets you use a wildcard as the value of its Property parameter. This lets you display detailed information.
Often, objects include more information than you need, which is why PowerShell doesn't show all property values by default. The following command generates over 60 lines of output for a single process:. Although the Format-List command is useful for showing detail, if you want an overview of output that includes many items, a simpler tabular view is often more useful. If you use the Format-Table cmdlet with no property names specified to format the output of the Get-Process command, you get exactly the same output as you do without a Format cmdlet.
By default, PowerShell displays Process objects in a tabular format. Although a tabular view is useful for displaying lots of information, it may be difficult to interpret if the display is too narrow for the data.
In the previous example, the output is truncated. If you specify the AutoSize parameter when you run the Format-Table command, PowerShell calculates column widths based on the actual data displayed.
