PowerShell command in a batch script

Question

I'm new, so apologies if I'm not asking correctly.

I'm selecting a part of a text file and generating a new one with just that part with this code:

Select-String -Path .\input_file.txt -Pattern '\b\d{1,2}\.\d{1,2}\b' -AllMatches | % { $_.Matches } | % { $_.Value } > .\output_file.txt

This works when I execute it on PowerShell but now I need to do the same with a bunch of files in a directory... Is there a way to do the same as a batch script?

I'm not able to figure it out :(

Many thanks in advance!

With Powershell, you can iterate through a list of files and execute a command afterwards.

For example:

# get all textfiles in a variable.
$files = get-childitem *.txt

# Loop collection and perform action on each iteration
$files | foreach-object {
    $filename = $_.name
    Select-String -Path $filename -Pattern '\b\d{1,2}\.\d{1,2}\b' -AllMatches | `
        % { $_.Matches } | % { $_.Value } >> .\output_file.txt

}
