Demo Create Bucket using AWS CLI

In this guide, you’ll master using the AWS CLI to manage Amazon S3 buckets and objects. We’ll walk through listing buckets, creating buckets, copying and moving files, syncing directories, and cleaning up objects and buckets—all with practical examples.

Prerequisites

AWS CLI v2 installed and configured with appropriate IAM permissions.
Basic familiarity with your command-line interface (Windows, macOS, or Linux).

If you haven’t installed the AWS CLI, follow the official AWS CLI installation guide.

Quick Reference: Common S3 Commands

Operation	Command	Description
List all buckets	`aws s3 ls`	Show every S3 bucket in your AWS account
List bucket contents	`aws s3 ls s3://BUCKET_NAME`	Display objects in a specific bucket
Create a new bucket	`aws s3 mb s3://BUCKET_NAME`	Make a new bucket (region optional with `--region`)
Copy files	`aws s3 cp SOURCE DESTINATION`	Copy files between local and S3 or between buckets
Move files	`aws s3 mv SOURCE DESTINATION`	Move files (source deleted after successful copy)
Sync directories	`aws s3 sync SOURCE DESTINATION`	Mirror a directory (uploads only new or changed files)
Delete objects	`aws s3 rm s3://BUCKET_NAME/OBJECT`	Remove a single object
Delete a bucket	`aws s3 rb s3://BUCKET_NAME`	Remove a bucket (use `--force` to delete all objects first)

1. Listing Buckets and Contents

1.1 List All Buckets

aws s3 ls

Example output:

2023-04-05 19:01:36 kk-demo-117
2023-04-05 19:02:15 kk-demo-files
2023-04-05 18:51:39 kk-static-demo

1.2 List Objects in a Bucket

aws s3 ls s3://kk-static-demo

Sample:

2023-04-05 18:52:06     458  404.html
2023-04-05 18:52:07     414  index.css
2023-04-05 18:52:07    1136  index.html

1.3 Recursive Listing

aws s3 ls s3://kk-static-demo --recursive

This shows all objects, including those in nested “folders.”

2. Creating a Bucket

Use mb (make bucket) and specify a region if needed:

aws s3 mb s3://kk-cli-demo1 --region us-east-1

Output:

make_bucket: kk-cli-demo1

Verify by listing buckets again:

aws s3 ls

3. Copying Files with `cp`

3.1 Local → S3

Upload a single file:

aws s3 cp file1 s3://kk-cli-demo1

Rename while uploading:

aws s3 cp file2 s3://kk-cli-demo1/secondfile.txt

3.2 S3 → Local

Download an object to your current directory:

aws s3 cp s3://kk-cli-demo1/secondfile.txt .

3.3 Bucket-to-Bucket Copy

aws s3 cp s3://kk-cli-demo1/file1 s3://kk-static-demo/file1

4. Moving Files with `mv`

The mv command copies then deletes the source.

4.1 Local → S3

aws s3 mv file3 s3://kk-cli-demo1

4.2 S3 → Local

aws s3 mv s3://kk-cli-demo1/file3 .

5. Copying Directories Recursively

To upload an entire folder:

aws s3 cp media/ s3://kk-cli-demo1 --recursive

Verify the structure:

aws s3 ls s3://kk-cli-demo1 --recursive

6. Deleting Objects

Remove a single file:

aws s3 rm s3://kk-static-demo/file1

Deleting objects is irreversible. Double-check the object key before running aws s3 rm.

7. Syncing Directories

Make the destination mirror your source directory:

aws s3 sync . s3://kk-cli-demo1

Only new or updated files are transferred.

8. Deleting a Bucket

Attempt to delete an empty bucket:

aws s3 rb s3://kk-cli-demo1

If the bucket isn’t empty, use:

aws s3 rb s3://kk-cli-demo1 --force
