AWS CLI: Controlling AWS from Your Terminal

The AWS Command Line Interface turns complex console clicks into simple commands. When I first installed the CLI, I felt like a power user. You can launch instances, upload files to S3, and manage almost any service from your terminal. Setup involves installing the CLI, creating an IAM user with programmatic access, and running `aws configure` to set your credentials. The `--dry-run` option is your friend—it checks permissions without executing. You can also use `--query` and `--output` to format results. It's essential for automation and scripting.
