## What is the AWS Command Line Interface?

<br>

* An **open source tool** that allows you to interact with AWS services using the command-line shell
* With AWS CLI, you can run commands with **minimal configuration** from your desired terminal program that implement the same functionality provided by the browser-based AWS Management Console
  * `Linux shells`
    * Run commands on **Linux** or **MacOS** using common shell programs like **bash**, **zsh**, **tcsh**
  * `Windows command line`
    * On Windows, run commands using **PowerShell** or **Windows command prompt**
  * `Remotely`
    * Run commands on **EC2** instances through remote terminal programs like **PuTTY**, **SSH**, or **AWS Systems Manager**
