How to run a PowerShell script

Solution 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

Solution 2:

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

Solution 3:

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>
