How to read/search specific content in a webpage using shell scripting

Question

I'm a beginner in shell scripting.

I'm trying to write a script in which a part of it involves reading the value from a webpage. In this case, The shell script tries to fetch the IMDB rating of a movie by going to the movie's IMDB page.

Can someone suggest me how i can achieve this & also what are the topics i need to learn ?

Thank you.

You can use wget and curl to get the page. Then you'll need to use regex or some other string manipulation to get the information you need from that. It would be a lot easier to use a library to do some of these things for you.
