bash - filter folders by name with "@" at beggining : I do have folder with folders

    my_folders
        @folder1
        @next_one
        some_folder_without_at
        @third
        some_file.txt

I got so far adding all folders

    for /d %%i in ("C:\my\path\to\my_folders\*") do (
    	call :setfolders %%i
    )

Goal: I want to filter result and add **only folders with @ at beggining**
