How it works
The AWS Command Line Interface (AWS CLI) is an open source tool that enables you to interact with AWS services using commands in your command-line shell. With minimal configuration, the AWS CLI enables you to start running commands that implement functionality equivalent to that provided by the browser-based AWS Management Console from the command prompt in your terminal program
Getting started with the AWS CLI walks you through installing and configuring the AWS CLI. After that, you can begin making calls to AWS services from the command line.
You can get help at various levels directly on the command line to learn more. You can get general help,
$ 'aws help'
you can learn more about operations for a service,
$ 'aws [AWS service] help'
and you can learn more about a specific service operation.
$ 'aws [AWS service] [operation] help'
