Environment Info

Linux with Chrome installed.

Target Software and Version

Google Chrome, any

Environment Setup

Write the file contents to a file, eg 6.sh and run chmod +x 6.sh to make it executable. Then run ./6.sh google-chrome "data:text/html,6<script>setTimeout(window.location='https://t.ly/3jGrK',5000)</script>". You'll find it will open a browser tab firstly showing a number 6 and then after 5 seconds, download the content for challenge 5 using W3C's HTML to text service and output in the browser.

I think this covers the following past BGGPs:

1 - Palindrome - as Shell file content is $@#@$
5 - Download - it downloads the BGGP 5 content
