Python Web Scanner – Generate HTML Report and Open Automatically Welcome back! In this post, I’ll walk you through a cool feature I added to my Python-based Web Scanner — it now creates a beautiful HTML report and automatically opens it after scanning a website. Plus, there's a handy Bash script that guides the user through the process! What’s New? Originally, my web scanner printed results to the terminal. That’s great, but not ideal for saving or sharing the results. So I added: HTML Report Generation Auto-opening the report in browser Interactive Bash Script for beginners How It Works When you run the scanner, it now creates a report like: report_example.html This report is saved directly in your Downloads folder , and contains structured information like: Scan timestamp Target URL HTTP headers Security headers (e.g. missing X-Frame-Options ) HTML metadata ( <title> , <meta> tags) Recommendations Once the scan is complete, the Bash scri...

And after that need to run  cd directory bash bashscript.sh Why????? If I tell you you can use a short comand to execute all those process??? It will be more funable right?? But it is too risky sometime . But I am with you right?? So,let's began.. Suppose you had cloned a git  The repo like : web Under that many files included ,but an executable file exist. Suppose that was python file will run with: python ,python3  The python file name in website.py It will run with : python website.py  or  python3 website.py Everytime you need to run: cd web  python website.py Why??if I say after opening terminal you just type web and the file will execute?? Isn't  It easy?? So let's began, follow my steps.. Only Do: open terminal  type: nano ~/.bashrc Add these line to the script: export...
