Search File Paths Based on File Name Array

Question

I have two string arrays in my PowerShell script:

$search = @('File1', 'File2');
$paths = @('C:\Foo\File1.pdf', 'C:\Foo\Bar.doc', 'C:\Foo\File2.txt');

How can I get all file paths which contain the file names from the search array? Can this be done in a pipeline?

Answer 1

If you need to do partial matches you could do something like this:

$paths | Where-Object {
  $filename = Split-Path $_ -Leaf
  $search | Where-Object { $filename -like "*$_*" }
}

Answer 2

You could use the GetFileNameWithoutExtension method to retrieve the filename of the path and use -in to filter them:

$paths | ? { [System.IO.Path]::GetFileNameWithoutExtension($_) -in $search }
