# AWS CLI v2 Quick Reference

A unified tool to manage AWS services from the terminal. This guide focuses on CLI v2 features, practical examples, and advanced patterns for experienced developers.

## Quick Start

```bash
# Verify installation and version
aws --version

# Interactive configuration
aws configure                    # Access keys + region + output format
aws configure sso               # IAM Identity Center (SSO) - recommended

# Verify identity
aws sts get-caller-identity     # Shows Account, UserId, ARN

# Enable auto-prompt for command discovery
aws dynamodb --cli-auto-prompt
```

## Power User Tips

```bash
# See all waiter commands for a service
aws ec2 wait help

# Generate command skeleton (fill in the blanks)
aws lambda create-function --generate-cli-skeleton > create-fn.json

# Create CLI alias for common commands
aws configure set cli_alias.whoami "sts get-caller-identity"
aws whoami  # Now works!

# Disable pager for scripting
export AWS_PAGER=""
```
