Day #5: AWS CLI

Day #5: AWS CLI

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.

The command line is really really powerful tool.It enables you to interact with the AWB as a platform anywhere in the world so you can interact directly with the platform with your laptop using the command line so you can go in and provision things like easy to create instances or S3 Buckets without using the AWS console.

Can be directly downloaded from AWS CLI to use AWS: CLI you need to have programatic command line access while creating your user and can work with

1. Linux shells– bash, zsh, and tcsh to run commands in Linux or macOS.
2. Windows command line – Powershell.
3. Remotely -Remote terminal, ssh, putty.

Benefits of CLI

1. More control
2. Saves times
3. Scripting
4. Support all AWS service

After downloading first aws command that can configure and set up your system is aws configure Some basics AWS Commands
