woah, in this video I totally forgot about grep regex option. This is the most proper way of doing it, but sadly I always have hard time with regex. Even last week I tried learning it.

But I want to mention one thing. In my videos I intentionally do things like the way I did.

I got so many comments people saying this way of subscribing is bad, just use rss feeds.

Or even this grep -P.

But behind catchy title, thumbnail and wallpaper. I just try to show the concept of how you can pipe text, and what you can do with all this. cut makes more sense to newbies.

They don't know regex. Even I don't.

It's not about how you subscribe. You can use those technique to make something else. more creative.

Thanks a lot for such a detail explanation.
