HELP ME CRACK THIS PLEASE!

I've got an assignment and one of the module is shell scripting

I had no idea abt bash, but thanks to chatgpt I did most of it

But there's one q. It got an access.log file

Analyze log file, count HTTP status code 200,404,408,503 , save each count with the specific message into seperate files (and display them). And create NoErrors only if none are found

Can someone help me solve this in my dms I've tried 3 diff ways But I think the key is to understand the data format in log file?
