Application : quiet install command with powershell command

Question

Hi,

I would like to create a standard Application with powershell commands.
I make it with a script, in the Quiet install commad I strike : powershell.exe -ExectutionPolicy ByPass .\myScript.ps1
And it works fine.
But if I strike : powershell.exe -noExit -noProfile -Command '& {'& {$Env:ProgramFiles;Copy-Item .* "$Env:ProgramFiles\WindowsPowerShell\Modules" -Recurse -Force -WhatIf;Read-Host "Wait !!!"}'
I got in my powershell console just the string, not the execution of the string.

What is the right expression to use ?

Thank you for your help.

Ludovic.

Answer 1

powershell.exe /? help me !!!

Pour écrire une chaîne qui exécute une commande Windows PowerShell,
utilisez le format :
    "& {<commande>}"
où les guillemets indiquent une chaîne et l’opérateur d’appel (&)
entraîne l’exécution de la commande.

I change my ' by " and adapt my " by ' and it works fine now.
