Javascript tool built in NodeJS to automatically get body's content from HTTP/HTTPS request and concatenate to a file.

npm install -g chupa-cabra 

Just run the chupa-cabra and when it asks for the URL you can:

https://www.google.com.br/search?q=test&start=[0,100,10]

It means from 0 to 100 incremented by 10. All the 10 pages will be dumped into a text file, in this case, as HTML.

http://api.example.com/resource?page=[0,1000,100]

In this case from 0 to 1000 incremented by 100. The JSON result will be appended into a txt file.

https://www.google.com

Gets the HTML content for just this page.
