How to run a Powershell script from the command line and pass a directory as a parameter

try this:

powershell "C:\Dummy Directory 1\Foo.ps1 'C:\Dummy Directory 2\File.txt'"

you are calling a script file not a command so you have to use -file eg :

powershell -executionPolicy bypass -noexit -file "c:\temp\test.ps1" "c:\test with space"

for PS V2

powershell.exe -noexit &'c:\my scripts\test.ps1'

(check bottom of this technet page http://technet.microsoft.com/en-us/library/ee176949.aspx )

Using the flag -Command you can execute your entire powershell line as if it was a command in the PowerShell prompt:

powershell -Command "& '<PATH_TO_PS1_FILE>' '<ARG_1>' '<ARG_2>' ... '<ARG_N>'"

This solved my issue with running PowerShell commands in Visual Studio Post-Build and Pre-Build events.
