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

Question

PowerShell -Command   Foo ps1    Foo ps1   Function Foo  directory        echo  directory    if   args Length -eq 0        echo  Usage  Foo  lt directory gt     else       Foo  args 0       Despite Foo ps1 being in the directory from where I am calling Powershell  this results in   The term    Foo ps1  is not recognized as the name of a cmdlet  function  script file  or operable program   Check the spelling of the name  or if a path was included  verify that the path is correct and try again     EDIT  Wasn t working because PowerShell was changing directory due to profile ps1 containing cd C       I then tried to call it specifying the full path to the script file  but no matter what I try  I can t get it to work  I believe I have to quote the path because it contains whitespaces  as does the file name I need to pass in an argument to the script    Best guess so far   PowerShell -Command   C  Dummy Directory 1 Foo ps1   C  Dummy Directory 2 File txt     Outputs error    Unexpected token  C  Dummy Directory 2 File txt  in expression or statement   At line 1 char 136

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'

Using the flag -Command you can execute your entire powershell line as if it was a command in the PowerShell prompt   powershell -Command   amp    lt PATH TO PS1 FILE gt     lt ARG 1 gt     lt ARG 2 gt         lt ARG N gt      This solved my issue with running PowerShell commands in Visual Studio Post-Build and Pre-Build events
