AWS Resource Listing Shell Script

A Bash script that lists AWS resources using the AWS CLI. The script accepts an AWS region and a service name as input and displays the corresponding AWS resources in a formatted table.

This project demonstrates Linux shell scripting, AWS CLI usage, conditional statements, argument validation, and AWS resource management.

---

Features

• Lists resources from multiple AWS services
• Accepts AWS Region and Service Name as command-line arguments
• Validates user input
• Checks whether AWS CLI is installed
• Checks whether AWS CLI is configured
• Displays output in a readable table format
• Easy to extend with additional AWS services

---

Technologies Used

• Bash Shell Scripting
• AWS CLI v2
• Ubuntu Linux (EC2)
• Amazon EC2
• Git & GitHub
