I’ve used the grep command many times but haven’t written an article to learn about grep. It seems like a good idea to do so so I can reference this article. That’s something that’s considered a good thing.
The thing is, I’ve tried to write this article before and it just came out terrible. That article never got published. It just wasn’t good enough. As you’ve seen the quality of some of these articles, tells you how bad that attempt went.
You won’t need to install anything for this article. If you’re using a desktop or a server, you have grep. I’d expect to find grep in embedded systems because it’s just a useful tool. I suppose some companies might have ripped it out of their devices to save space and stop you from rooting around and messing with things.
So, I decided I’d do what I’d done before. I reached out to my buddy ChatGPT and asked them to write an article. Sure enough, ChatGPT did a fine job at it. This doesn’t save me much time. I still need to do all the formatting and that takes more time than you might expect.
