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

Add the param declation at the top of ps1 file

test.ps1

param(
  # Our preferred encoding
  [parameter(Mandatory=$false)]
  [ValidateSet("UTF8","Unicode","UTF7","ASCII","UTF32","BigEndianUnicode")]
  [string]$Encoding = "UTF8"
)

write ("Encoding : {0}" -f $Encoding)

result

C:\temp> .\test.ps1 -Encoding ASCII
Encoding : ASCII

Change your code to the following    Function Foo  directory                echo  directory            if   args Length -eq 0                echo  Usage  Foo  lt directory gt             else               Foo  string    args          And then invoke it as      powershell -ExecutionPolicy RemoteSigned -File  c  foo ps1   c  Documents and Settings   c  test

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  amp  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   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
