Powershell start process

The Start-Service cmdlet sends a start message to the Windows Service Controller for each of the specified services. If a service is already running, the message is ignored without error. You can specify the services by their service names or display names, or you can use the InputObject parameter to supply a service object that represents the services that you want to start.

This example starts the EventLog service on the local computer. The Name parameter identifies the service by its service name. This example shows what would occur if you started the services that have a display name that includes "remote".

The DisplayName parameter identifies the services by their display name instead of their service name. The WhatIf parameter causes the cmdlet to display what would happen when you run the command but does not make changes. This example starts the Windows Management Instrumentation WMI service on the computer and adds a record of the action to the services. Next, we start the service. Without the PassThru parameter, Start-Service does not create any output. The pipeline operator passes the object output by Start-Service to the Format-List cmdlet to format the object as a list of its properties.

The output is added to the end of the existing file. This example shows how to start a service when the start type of the service is Disabled. The first attempt to start the Telnet service tlntsvr fails. The Set-Service cmdlet changes the start type to Manual.

Now, we can resubmit the Start-Service command. This time, the command succeeds. To verify that the command succeeded, run Get-Service. Specifies services that this cmdlet omits. The value of this parameter qualifies the Name parameter.

Wildcard characters are permitted. Specifies services that this cmdlet starts. Specifies ServiceController objects representing the services to be started. Enter a variable that contains the objects, or type a command or expression that gets the objects.

The parameter name is optional.PowerShell is an advanced form of command prompt. It is extended with a huge set of ready-to-use cmdlets and comes with the ability to use. Today, I will show you how to start a process elevated from the PowerShell prompt.

So, it is a good idea to learn this useful trick which can be performed from the PowerShell console and save your time. For this task, we'll use the Start-Process cmdlet. It supports a number of optionsone of them is -Verb.

If you specify -Verb as "RunAs", the process you are going to start will be opened elevated. A UAC prompt will appear. Confirm it: The Notepad app will be opened elevated.

You can ensure this using the Task Manager.

See the article: How to check if a process is running as administrator elevated in Windows Note: If you press the "No" button at the UAC prompt, the PowerShell console will print out an error message "The operation was canceled by the user.

This is expected. Tip: You can run an app elevated with the help of PowerShell directly without opening its console first. For example, you can create a shortcut or type the following command in the Run dialog:.

The result will be the same. The Powershell window will flash for a moment and then the app will be opened elevated. If you need to pass some arguments also known as switches or parameters to a process that you are going to start elevated from PowerShell, use the -Argument switch of the Start-Process cmdlet.

Argument specified there will be passed to the target executable file. Here are modified examples with Notepad. Enclose the paths that have spaces in quotes. If you need to pass more than more argument, separate them with commas and use ArgumentList:.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Is there a way I can pass parameters to MSBuild using start-process? I'm open to not using start-process, the only reason I used it was I needed to have the "command" as a variable.

If you run PowerShell from a cmd. I discovered this when my C Explorer program is used to open a cmd. It appears that any PowerShell which is a 'win32 job' of cmd.

I've found using cmd works well as an alternative, especially when you need to pipe the output from the called application espeically when it doesn't have built in logging, unlike msbuild.

Thanks jeffamaphone, this was some good reference info also. Keep in mind that Start-Process is a new feature in V2. The information in that post is very good but some of it is not really necessary anymore in V2.

Start-Process itself is new to V2? Can you elaborate a little? I don't have any machine with V1 installed to test.The Wait-Process cmdlet waits for one or more running processes to be stopped before accepting input. In the PowerShell console, this cmdlet suppresses the command prompt until the processes are stopped. This example stops the Notepad process and then waits for the process to be stopped before it continues with the next command.

The third command uses Wait-Process to wait until the Notepad process is stopped. It uses the Id parameter of Wait-Process to identify the process. These commands show three different methods of specifying a process to Wait-Process. The second command uses the Id parameter, the third command uses the Name parameter, and the fourth command uses the InputObject parameter.

powershell start process

This command waits 30 seconds for the Outlook and Winword processes to stop. If both processes are not stopped, the cmdlet displays a non-terminating error and the command prompt.

Specifies the process IDs of the processes. To specify multiple IDs, use commas to separate the IDs. Specifies the processes by submitting process objects. Enter a variable that contains the process objects, or type a command or expression that gets the process objects, such as the Get-Process cmdlet.

Specifies the process names of the processes. To specify multiple names, use commas to separate the names. Wildcard characters are not supported. Specifies the maximum time, in seconds, that this cmdlet waits for the specified processes to stop.

When this interval expires, the command displays a non-terminating error that lists the processes that are still running, and ends the wait.

By default, there is no time-out. This cmdlet uses the WaitForExit method of the System. Process class. For more information about this method, see the Microsoft. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode.

Stop-Process works only on processes running on the local computer. On Windows Vista and later versions of the Windows operating system, to stop a process that is not owned by the current user, you must start PowerShell by using the Run as administrator option.

Also, you are not prompted for confirmation unless you specify the Confirm parameter. This command stops all instances of the Notepad process on the computer. Each instance of Notepad runs in its own process. It uses the Name parameter to specify the processes, all of which have the same name. If you were to use the Id parameter to stop the same processes, you would have to list the process IDs of each instance of Notepad.

This command stops a particular instance of the Notepad process. It uses the process ID,to identify the process. The Confirm parameter directs PowerShell to prompt you before it stops the process. Because the prompt includes the process namein addition to its ID, this is best practice. The PassThru parameter passes the process object to the formatter for display. Without this parameter, there would be no display after a Stop-Process command.

This series of commands starts and stops the Calc process, and then detects processes that have stopped. The third command stops the Calc process. It uses the InputObject parameter to pass the object to Stop-Process. The last command gets all of the processes on the computer that were running but that are now stopped. It uses Get-Process to get all of the processes on the computer. HasExited is just one property of process objects.

To find all the properties, type Get-Process Get-Member. These commands show the effect of using Force to stop a process that is not owned by the user. The first command uses Get-Process to get the Lsass process. A pipeline operator sends the process to Stop-Process to stop it.

As shown in the sample output, the first command fails with an Access denied message, because this process can be stopped only by a member of the Administrator group on the computer. When PowerShell is opened by using the Run as administrator option, and the command is repeated, PowerShell prompts you for confirmation.

The second command specifies Force to suppress the prompt. As a result, the process is stopped without confirmation. Stops the specified processes without prompting for confirmation.

By default, Stop-Process prompts for confirmation before stopping any process that is not owned by the current user. Specifies the process IDs of the processes to stop. To specify multiple IDs, use commas to separate the IDs. Specifies the process objects to stop. Enter a variable that contains the objects, or type a command or expression that gets the objects.We can start a process in PowerShell many different ways. The most common way is to use Start-Process because it's probably the most intuitive.

PowerShell is known for it's intuitive approach to command naming and Start-Process is an excellent choice. However, that command is limited. To understand why Start-Process and all of these other commands are limited you first have to understand how a typical EXE file works. When an EXE file is run, it performs whatever action it was designed to do; it pings something pingstarts a software installer setuplooks up some DNS record nslookupwhatever.

For this part, Start-Process and other commands to start a process work great. It's simple. The limitation comes when that EXE returns some output. An EXE file like many other executable files not limited to Windows has a concept of standard streams. Standard streams are how executable files return output. These streams come in three flavors; stdin, stdout, and stderr.

Stdin is the stream that can get passed into the executable which we won't be focusing on here. Stdout is the stream that the executable uses to send normal non-error output. In PowerShell terms, think of stdout as what Write-Output returns. When an error occurs depending on if the developer of the executable wrote it correctlythe executable should return output via stderr. This is a stream that's set aside for returning any error information. These streams allow users of these executable files to differentiate between what's typical output and what's an error.

Streams have been around for decades and Windows thus PowerShell know all about them and have adopted their own. An exit code, return code or result code is another age-old concept that executable files follow as well. An exit code is an integer that allows the executable to signal a status to the user when it exits. There are some standard exit codes that programs are supposed to follow like if the exit code is 0, everything is fine, exit code means it needs a reboot and so on.

Exit codes are another method that the executable file communicates to the user. Now that you understand what we're working with let's use an example.The Start-Process cmdlet starts one or more processes on the local computer.

To specify the program that runs in the process, enter an executable file or script file, or a file that can be opened by using a program on the computer. If you specify a non-executable file, Start-Process starts the program that is associated with the file, similar to the Invoke-Item cmdlet.

You can use the parameters of Start-Process to specify options, such as loading a user profile, starting the process in a new window, or using alternate credentials. This example starts a process that uses the Sort.

The command uses all of the default values, including the default window style, working folder, and credentials. This example starts a process that sorts items in the Testsort. Any errors are written to the SortError. The UseNewEnvironment parameter specifies that the process runs with its own environment variables. This example starts the Notepad.

It maximizes the window and retains the window until the process completes. This example shows how to find the verbs that can be used when starting a process. The available verbs are determined by the filename extension of the file that runs in the process. The example uses New-Object to create a System. ProcessStartInfo object for PowerShell. Both commands start the Windows command interpreter, issuing a dir command on the 'Program Files' folder.

Because this foldername contains a space, the value needs surrounded with escaped quotes. Note that the first command specifies a string as ArgumentList. The second command a string array. Specifies parameters or parameter values to use when this cmdlet starts the process. If parameters or parameter values contain a space, they need surrounded with escaped double quotes.

Specifies a user account that has permission to perform this action.

powershell start process

By default, the cmdlet uses the credentials of the current user. If you type a user name, you're prompted to enter the password. Specifies the optional path and filename of the program that runs in the process. Enter the name of an executable file or of a document, such as a.
