How to run a PowerShell script

Question

How do I run a PowerShell script?

• I have a script named myscript.ps1
• I have all the necessary frameworks installed
• I set that execution policy thing
• I have followed the instructions on this MSDN help page and am trying to run it like so: powershell.exe 'C:\my_path\yada_yada\run_import_script.ps1' (with or without --noexit)

which returns exactly nothing, except that the file name is output.

No error, no message, nothing. Oh, when I add -noexit, the same thing happens, but I remain within PowerShell and have to exit manually.

The .ps1 file is supposed to run a program and return the error level dependent on that program's output. But I'm quite sure I'm not even getting there yet.

What am I doing wrong?

Answer 1

1. Launch Windows PowerShell, and wait a moment for the PS command prompt to appear

2. Navigate to the directory where the script lives

   PS> cd C:\my_path\yada_yada\ (enter) 

3. Execute the script:

   PS> .\run_import_script.ps1 (enter) 

What am I missing??

Or: you can run the PowerShell script from cmd.exe like this:

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

according to this blog post here

Or you could even run your PowerShell script from your C# application :-)

Asynchronously execute PowerShell scripts from your C# application
