How to run a PowerShell script

Prerequisites:

You need to be able to run PowerShell as an administrator

You need to set your PowerShell execution policy to a permissive value or be able to bypass it

Steps:

Launch Windows PowerShell as an Administrator, and wait for the PS> prompt to appear Navigate within PowerShell to the directory where the script lives: PS> cd C:\my_path\yada_yada\ (enter) Execute the script: PS> .\run_import_script.ps1 (enter)

Or: you can run the PowerShell script from the Command Prompt (cmd.exe) like this:

powershell -noexit "& ""C:\my_path\yada_yada\run_import_script.ps1""" (enter)

according to Invoking a PowerShell script from cmd.exe (or Start | Run) by Kirk Munro.

Or you could even run your PowerShell script asynchronously from your C# application.

---

If you are on PowerShell 2.0, use PowerShell.exe's -File parameter to invoke a script from another environment, like cmd.exe. For example:

Powershell.exe -File C:\my_path\yada_yada\run_import_script.ps1

---

If you want to run a script without modifying the default script execution policy, you can use the bypass switch when launching Windows PowerShell.

powershell [-noexit] -executionpolicy bypass -File <Filename>

---

Type:

powershell -executionpolicy bypass -File .\Test.ps1

NOTE: Here Test.ps1 is the PowerShell script.

---

I've had the same problem, and I tried and tried... Finally I used:

powershell.exe -noexit "& 'c:\Data\ScheduledScripts\ShutdownVM.ps1'"

And put this line in a batch-file, and this works.

---

If you only have PowerShell 1.0, this seems to do the trick well enough:

powershell -command - < c:\mypath\myscript.ps1

It pipes the script file to the PowerShell command line.

---

Pretty easy. Right click the .ps1 file in Windows and in the shell menu click on Run with PowerShell.

---

Using cmd (BAT) file:

@echo off
color 1F
echo.

C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File "PrepareEnvironment.ps1"

:EOF
echo Waiting seconds
timeout /t 10 /nobreak > NUL

If you need run as administrator:

Make a shortcut pointed to the command prompt (I named it Administrative Command Prompt) Open the shortcut's properties and go to the Compatibility tab Under the Privilege Level section, make sure the checkbox next to "Run this program as an administrator" is checked

---

An easy way is to use PowerShell ISE, open script, run and invoke your script, function...

I have a very simple answer which works:

Open PowerShell in administrator mode Run: set-executionpolicy unrestricted Open a regular PowerShell window and run your script.

I found this solution following the link that was given as part of error message: About Execution Policies

Edit: Make sure to run set-ExecutionPolicy default once you're done, or you will be exposed to seurity risks (thanks Anonymous user).

---

If your script is named with the .ps1 extension and you're in a PowerShell window, you just run ./myscript.ps1 (assuming the file is in your working directory).

This is true for me anyway on Windows 10 with PowerShell version 5.1 anyway, and I don't think I've done anything to make it possible.

---

In case you want to run a PowerShell script with Windows Task Scheduler, please follow the steps below:

Create a task Set Program/Script to Powershell.exe Set Arguments to -File "C:\xxx.ps1"

It's from another answer, How do I execute a PowerShell script automatically using Windows task scheduler?.

---

Give the path of the script, that is, path setting by cmd: $> . c:\program file\prog.ps1

Run the entry point function of PowerShell: For example, $> add or entry_func or main

---

You can run from cmd like this:

type "script_path" | powershell.exe -c -

---

Use the -File parameter in front of the filename. The quotes make PowerShell think it is a string of commands.

---

With the appropriate execution policy, you should just be able to call the file directly and Windows will associate it with PowerShell

C:\my_path\yada_yada\run_import_script.ps1

That does not do so well with arguments. The real answer to your question is that you are missing the & to say "execute this"

powershell.exe '& C:\my_path\yada_yada\run_import_script.ps1'

---

Open Power-shell Move the folder where the .ps1 file available ex. cd c:\users\ Now type your powershell file name ex.testfile.ps1 Press Enter

This should execute your simple powershell script.

---

I've just found the method what Microsoft do when we right click on a ps1 script and click on "Run with PowerShell" :

"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & 'C:\Users\USERNAME\Desktop\MYSCRIPT.ps1'"
