AWS CLI Commands

Managing AWS from the command line.

S3

aws s3 cp

Copies files to, from, or between S3 buckets.

aws s3 sync

Synchronizes a local directory and an S3 bucket, uploading only changed files and optionally deleting removed ones.

aws s3 ls

Lists S3 buckets or the objects within a bucket/prefix.

EC2

aws ec2 describe-instances

Describes one or more EC2 instances and their current state.

aws ec2 start-instances

Starts one or more stopped EC2 instances.

aws ec2 stop-instances

Stops one or more running EC2 instances.

Setup

aws configure

Interactively sets up credentials, default region, and output format for the CLI.

aws sts get-caller-identity

Shows which AWS identity (account/user/role) the current credentials belong to — the fastest way to check what you're authenticated as.

CloudWatch

aws logs tail

Tails a CloudWatch Logs group, optionally following new events as they arrive.

CloudFront

aws cloudfront create-invalidation

Invalidates cached objects in a CloudFront distribution so the next request re-fetches them from the origin.
