This blog is for the total beginner or someone who just started to learn AWS and Linux and doesn't have prior knowledge working with AWS CLI Let me start with what is CLI<command line interface> A short brief: I will tell you what is AWS CLI and how to install it Trust me, it will be a game-changer for you to know why you use AWS CLI.

CLI is a text-based interface used to interact with our operating system (OS) by typing commands on the terminal. Users can interact with OS or software by writing commands onto the command prompt or terminal.

a user can use it for many things, such as resource efficiency, automation, scripting, etc. If you are familiar with commands, there are many examples of command-line interfaces such as Unix/Linux, windows command prompt, PowerShell, MacOS Terminal, etc.

The AWS CLI (Command Line Interface) is a sophisticated tool that allows users to connect with Amazon Web Services (AWS) via the command line. Here are several instances in which you may utilize the AWS CLI:

Automating Tasks

Managing Resources

Integration with Other Tools

Access Control and Security

Monitoring and Logging

Cost Management

Let's discuss the prerequisites needed before the installation of AWS CLI.

AWS Account and IAM credentials

IAM credentials are very easy to create; you can follow through AWS documentation, and many YouTube videos are there too.

Steps to Install AWS CLI into Your OS :

make sure you always install the latest version of aws cli for up-to-date packages. if you have aws cli v1 and want to install aws cli v2 then remove the older AWS CLI so that you can reinstall it with a newer version.

sudo yum remove awscli

...

Install AWS CLI on EC2 instances

You must have a nat<network access translation> or internet gateway for an internet connection.

for Linux OS users

• Linux x86 (64-bit)

  sudo curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" unzip awscliv2.zip sudo ./aws/install

If your Linux distribution does not provide a built-in unzip command, you can use an equivalent or install it. The following command unzips the package and creates the aws directory in the current directory.

unzip awscliv2.zip

if your Linux OS throws the error 'unzip' command not found, then install it through these commands

sudo apt install unzip

or check your Linux distro and use the command accordingly, AWS CLI might not get Installed if you do not have the unzip command installed, which means it will be there but not properly installed Check if it is installed or not by running these commands

aws configure

If it shows something like 'AWS access key ID [none]', it means it's there. you need to enter the IAM credentials [access key + secret key] combination of these two and regions. You can add or leave it as it is if you want.
