There is an existing question of how to run a ps1 file when you double click found here. However I want to know if there is a solution that does not require 2 separate files.

One method is to embed the Powershell script into a .bat file with a combination of echos and comments:

echo `
REM | Out-Null <#
powershell.exe -ExecutionPolicy Bypass -Command "iex ((Get-Content \"%~f0\") -join \"`n\") | Out-Null"
goto :eof
#>

(powershell script here)

<#
:eof
::#>

This results in some artifacts in the console output but the script is successfully run embedded in a bat file. This works without errors because "echo" is both a Windows Command Line command as well as a Powershell command.

EDIT: Here I am years later with an improved version:

@powershell.exe -ExecutionPolicy Bypass -Command "$_=((Get-Content \"%~f0\") -join \"`n\");iex $_.Substring($_.IndexOf(\"goto :\"+\"EOF\")+9)"
@goto :EOF

(powershell script here)

Improvements:

  • Only requires a 2 line file header (I didn't know about :EOF)
  • No console output unless you do so from the script
  • Compatible with Write-Output due to only passing the actual script content to powershell.exe

An enhancement: instead @goto :EOF, I'm using exit %ERRORLEVEL% and $_.IndexOf('exit' + ' ') to allow propagation of exit code.
