A positional parameter cannot be found that accepts argument '\'

Question

I am trying to get the meta data from a directory and I am getting an error that A positional parameter cannot be found that accepts argument '\'. Not sure how to correct this?

$FileMetadata = Get-FileMetaData -folder (Get-childitem $Folder1 + "\" + $System.Name + "\Test" -Recurse -Directory).FullName

Answer 1

You need to do the concatenation in a subexpression:

$FileMetadata = Get-FileMetaData -folder (Get-childitem ($Folder1 + "\" + $System.Name + "\Test") -Recurse -Directory).FullName

or embed the variables in a string like this:

$FileMetadata = Get-FileMetaData -folder (Get-childitem "$Folder1\$($System.Name)\Test" -Recurse -Directory).FullName

Answer 2

The most robust way in Powershell to build a path when parts of the path are stored in variables is to use the cmdlet Join-Path.

This also eliminate the need to use "\".

So in your case, it would be :

$FoldersPath = Join-Path -Path $Folder1 -ChildPath "$System.Name\Test"

$FileMetadata = Get-FileMetaData -folder (Get-ChildItem $FoldersPath -Recurse -Directory).FullName
