Key Benefits

• Speed: Execute tasks in seconds with simple commands.
• Automation: Script repetitive tasks to save time.
• Flexibility: Access almost all AWS services through the CLI.
• Cross-Platform: Compatible with Windows, macOS, and Linux.

🔧 Installing and Configuring AWS CLI

Installation

For Windows, download the MSI installer from the AWS CLI official page. Run the installer and follow the prompts.

For macOS/Linux, use these commands:

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

unzip awscliv2.zip

sudo ./aws/install

Verify the installation with:

aws --version

Configuration

Set up IAM credentials in the AWS Management Console by creating a user with programmatic access. Save your Access Key ID and Secret Access Key, then run:

aws configure

Input the following:

1. Access Key ID
2. Secret Access Key
3. Default region (e.g., us-east-1)
4. Default output format (json, table, or text)

• List S3 buckets: aws s3 ls
• Start an EC2 instance: aws ec2 start-instances --instance-ids <instance-id>
• Stop an EC2 instance: aws ec2 stop-instances --instance-ids <instance-id>
• Upload a file to S3: aws s3 cp myfile.txt s3://<bucket-name>/myfile.txt
