[VanshGarg06]

Describe the bug

There are some chapters missing on the listing on the homepage which should be added so that the viewer and users know what is inside the book. There are several topics which are missing like Adding the menu after Create an interactive menu in bash, Script requirements before Sending emails with bash and smtp, Password generator Bash script after Sending emails with bash and smtp, Redirection in Bash ,piping , HereDocument, HereString, Automatic wordpress ... , Prerequisites, Planning the functionality, the script and the full script before wrap up.

To Reproduce

1. Go to Website
2. Download the book
3. Compare Index and listing on the website
4. See Error

Expected behavior

The listing on the homepage is missing some of the elements of the book that are present in the book as i have downloaded the book and most of the topics of the books are not mentioned in the listing of the Homepage. The listing should match with the index of the book so that users could know what book will be including.

Additional context

Please assign this issue to me as i wanted to make the listing as same as the book downloaded from the website as if users could know that what all are included it will create the impact on users to download the book.
