What is the Command-line interface (CLI) and AWS (CLI)?

A command-line interface processes commands to a computer program in the form of lines of text. The program which handles the interface is called a command-line interpreter or command-line processor. Similarly, The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

Why we use AWS CLI?

AWS CLI gives you the ability to automate the entire process of controlling and managing AWS services through scripts. These scripts make it easy for users to fully automate cloud infrastructure. Prior to AWS CLI, users needed a dedicated CLI tool for just the EC2 service.
