How to pass parameters from cmd to a string array parameter in powershell-CodePudding

I have a cmd file which calls a powershell script which displays the input.

The input to the cmd is a list of filenames which it forwards it to the powershellscript which accepts a string array.

When trying it out, the whole list of filenames goes as one parameter.

I tried the answers at the link here and here but no luck.

Below is the output when I run the cmd.

C:\Users\User1>C:\Sample.cmd "C:\file1.txt C:\file2.txt"
Processing file - C:\file1.txt C:\file2.txt

Unfortunately the input to the cmd(list of files) are received from an external program that invokes it.

The powershell script goes like this:

param
(
    [Parameter(Position = 0, Mandatory = $true)]
    [string[]] $sourceFiles
)

Function Sample_function
{
Param
    (
        [Parameter(Position = 0, Mandatory = $true)]
        [string[]] $sourceFiles
    )
    
    foreach($file in $sourceFiles)
    {
        Write-Host "Processing file - $file"        
        
    }
}

Sample_function $sourceFiles

And the cmd goes like this:

@echo off

set PS_File="C:\Sample.ps1"

powershell -FILE "%PS_File%" %*

CodePudding user response：

In order to make an array parameter work with %*, use the ValueFromRemainingArguments setting:

param
(
    [Parameter(Position = 0, Mandatory = $true, ValueFromRemainingArguments = $true)]
    [string[]] $sourceFiles
)

Now PowerShell will correctly bind all expanded argument values to $sourceFiles even though they're separated by space and not ,
