What is AWS CLI

AWS CLI (Command Line Interface) is a unified tool provided by Amazon Web Services (AWS) that allows developers, system administrators, and other users to interact with various AWS services from the command line. It provides a consistent and efficient way to interact with AWS services, allowing users to automate tasks, build scripts, and integrate AWS functionality into their workflows and applications. It supports features like authentication and access control, output formatting options, and extensive documentation for each command.

How to Configure the AWS CLI

To configure the AWS CLI, follow these steps:

Verify AWS CLI installation:

To ensure the AWS CLI is installed correctly, open a terminal or command prompt and run:
```
 aws --version

```
It should display the version of the AWS CLI installed on your system.
