Nginx Log Analyser

The goal of this project is to help you practice some basic shell scripting skills. You will write a simple tool to analyze logs from the command line.

Requirements

Download the sample nginx access log file from here. The log file contains the following fields:

• IP address
• Date and time
• Request method and path
• Response status code
• Response size
• Referrer
• User agent

You are required to create a shell script that reads the log file and provides the following information:

1. Top 5 IP addresses with the most requests
2. Top 5 most requested paths
3. Top 5 response status codes
4. Top 5 user agents

Here is an example of what the output should look like:

Top 5 IP addresses with the most requests:
45.76.135.253 - 1000 requests
142.93.143.8 - 600 requests
178.128.94.113 - 50 requests
43.224.43.187 - 30 requests
178.128.94.113 - 20 requests

Top 5 most requested paths:
/api/v1/users - 1000 requests
/api/v1/products - 600 requests
/api/v1/orders - 50 requests
/api/v1/payments - 30 requests
/api/v1/reviews - 20 requests

Top 5 response status codes:
200 - 1000 requests
404 - 600 requests
500 - 50 requests
401 - 30 requests
304 - 20 requests

There are multiple ways to solve this challenge. Do some research on awk, sort, uniq, head, grep, and sed commands. Stretch goal is to come up with multiple solutions for the above problem. For example, instead of using awk, you can use grep and sed to filter and count the requests.
