{title:Description}

    {pstd}{cmd:open2} is a versatile command that opens files, directories, or executes system commands. It automatically detects the operating system (Windows, macOS, or others) and applies the appropriate logic to handle the request.

    {phang}{opt cd}
        Opens the current working directory in the system's file explorer.
