How to generate URL+title from URL list automatically? (using bash or other tool)

Question

Using Linux Bash, how can one turn a text file with:

http://example.org/
https://en.wikipedia.org/wiki/Main_Page
https://www.youtube.com/watch?v=mGQFZxIuURE

into:

http://example.org/ Example Domain
https://en.wikipedia.org/wiki/Main_Page Wikipedia, the free encyclopedia

?

How can one

1. pull a URL from a list of URLs in a file,
2. load the page,
3. extract its page title,
4. add that page title following that URL on the same line as the URL or on the line immediately following, then

perform those steps 1-4 for each subsequent URL in that list?

If not using Linux Bash, what other way is there?

Answer 1

With curl and pup:

while IFS= read -r url
do
   printf "%s " "$url"
   curl -sL "$url" | # fetch the page
       pup 'head title:first-of-type text{}' # get the text of the first title tag in head
done < input
