if you don't pass as argument the path where you want to download the files the script will run at the current directory:
bash htb-preview-downloader.sh
Otherwise:
bash htb-preview-downloader.sh /home/johndoe/htb
Since modern browser can not display the content of the preview lessons you have to use lynx:
lynx introduction-to-htb.html
And search for module overview
