Hi All,

I am having a powershell code to replace the value of the files in the specified path. i am not understanding how to convert the powershell script to batch script.
Please help me. In our environment we don't have access to powershell and i am new to scripting.

$files = Get-ChildItem -path C:\DATA\Files -filter *.txt
foreach ($file in $files)
{
    $content = Get-Content $file
    if ($content -match "99999999")
    {
        $content = $content -replace "99999999", $file.BaseName
        Set-Content $file $content
    }
}
