How to Start And Stop Processes In Powershell?

To start a process in PowerShell, you can use the Start-Process cmdlet followed by the name of the program or script you want to execute. For example, to start Notepad, you would type Start-Process notepad.exe.

To stop a process in PowerShell, you can use the Stop-Process cmdlet followed by the process ID (PID) or name of the process you want to terminate. For example, to stop the Notepad process, you could type Stop-Process -Name notepad.

You can also use the Get-Process cmdlet to retrieve information about running processes, including their names, IDs, and resource usage. This can be helpful when identifying which processes you want to start or stop.

How to stop multiple processes at once in PowerShell?

To stop multiple processes at once in PowerShell, you can use the following command:

1

Get-Process | Where-Object {$_.Name -eq "process_name"} | Stop-Process -Force

Replace "process_name" with the name of the processes you want to stop. This command will get all processes with the specified name and then stop them using the Stop-Process cmdlet with the -Force parameter to forcefully stop the processes.

Alternatively, you can stop multiple processes at once by their process IDs. You can use the following command:

1

Stop-Process -Id process_id1, process_id2, process_id3 -Force

Replace "process_id1", "process_id2", and "process_id3" with the process IDs of the processes you want to stop. This command will stop the processes with the specified process IDs using the Stop-Process cmdlet with the -Force parameter to forcefully stop the processes.

What is the proper way to pass arguments to a process in PowerShell?

In PowerShell, the proper way to pass arguments to a process is by using the Start-Process cmdlet. Here is an example of how to pass arguments to a process using Start-Process:

1

Start-Process -FilePath "C:\Path\To\Program.exe" -ArgumentList "arg1", "arg2", "arg3"

In this example, we are starting a process with the executable Program.exe located at "C:\Path\To" and passing three arguments "arg1", "arg2", "arg3" to the process.

You can pass multiple arguments by separating them with commas within the ArgumentList parameter of the Start-Process cmdlet.

What is the syntax to terminate a process in PowerShell?

To terminate a process in PowerShell, you can use the Stop-Process cmdlet. The syntax is as follows:

1

Stop-Process -Name <process_name>

Replace <process_name> with the name of the process you want to terminate. You can also use the following syntax to terminate a process by its process ID:

1

Stop-Process -ID <process_id>

Replace <process_id> with the process ID of the process you want to terminate.

How to set a process priority in PowerShell?

To set a process priority in PowerShell, you can use the Get-WmiObject cmdlet to retrieve the process object and then use the Win32_Process class to change the priority of the process. Here's an example of how you can set the priority of a process to "High" using PowerShell:

1. Open PowerShell as an administrator.
2. Use the Get-WmiObject cmdlet to retrieve the process object by specifying the process name or ID. For example, to retrieve the process object for "notepad.exe", you can use the following command:

1

$process = Get-WmiObject -Class Win32_Process -Filter "Name='notepad.exe'"

1. Once you have the process object, you can set the priority of the process to "High" by using the SetPriority method with a value of 128 (which corresponds to "High" priority). Here's how you can set the priority to "High":

1

$process.SetPriority(128)

1. After running the above command, the priority of the process should be set to "High".

Note: Changing the priority of a process can impact system performance and stability, so use this feature with caution.
