In this guide, we'll explore essential Amazon S3 operations—listing, creating, deleting buckets, and managing objects—using the AWS CLI. Automate your workflows and integrate these commands into scripts for seamless infrastructure management. ## Prerequisites * AWS CLI installed and configured (`aws configure`) * IAM permissions to list, create, and delete S3 buckets and objects * Unique bucket names (globally unique across AWS) Before creating a bucket, verify the name’s availability. Bucket names must be globally unique and compliant with DNS naming conventions. ## Quick Reference: Common S3 CLI Commands | Operation | Command | Description | | ---------------- | --------------------------------------------- | -------------------------------------------- | | List Buckets | `aws s3 ls` | Display all S3 buckets in the account | | Create Bucket | `aws s3 mb s3:// --region ...` | Make a new bucket in a specified region | | Delete Bucket | `aws s3 rb s3:// [--force]` | Remove an empty bucket or delete recursively | | List Objects | `aws s3 ls s3://` | Show top-level objects and prefixes | | Copy Files/Dirs | `aws s3 cp [--recursive]` | Copy files between local and S3 | | Move Files/Dirs | `aws s3 mv [--recursive]` | Move files between local and S3 | | Sync Directories | `aws s3 sync s3://` | Sync only new or changed files | | Delete Objects | `aws s3 rm s3:/// [--recursive]` | Remove objects or entire prefixes | *** ## 1. Listing S3 Buckets Retrieve all buckets in your AWS account: ```bash theme={null} $ aws s3 ls 2023-03-29 00:51:27 bucket1 2023-03-28 02:22:48 bucket2 2023-03-28 02:20:43 bucket3 ``` *** ## 2. Creating a New Bucket Use the **make bucket** command and specify a region: ```bash theme={null} $ aws s3 mb s3://newbucket --region us-east-1 make_bucket: newbucket ``` *** ## 3. Deleting a Bucket Remove an **empty** bucket: ```bash theme={null} $ aws s3 rb s3://newbucket remove_bucket: newbucket ``` To delete a bucket and all its contents, add `--force`: ```bash theme={null} $ aws s3 rb s3://newbucket --force remove_bucket: newbucket ``` Using `--force` is irreversible. All objects in the bucket will be permanently deleted. *** ## 4. Listing Objects Inside a Bucket ### 4.1 Top-Level Listing List prefixes (folders) and files at the root of the bucket: ```bash theme={null} $ aws s3 ls s3://newbucket PRE logs/ PRE media/ 2023-03-29 01:38:08 0 file1.txt 2023-03-29 01:38:09 0 file2.txt ``` ### 4.2 Recursive Listing Show every object under the bucket: ```bash theme={null} $ aws s3 ls s3://newbucket --recursive 2023-03-29 01:38:08 0 file1.txt 2023-03-29 01:38:09 0 file2.txt 2023-03-29 01:38:09 0 logs/log1 2023-03-29 01:38:09 0 logs/log2 2023-03-29 01:38:10 24599 media/images/image1.png 2023-03-29 01:38:10 21420 media/images/image2.png ``` *** ## 5. Copying Files ### 5.1 Local → S3 Upload a file without deleting the source: ```bash theme={null} $ aws s3 cp file1.txt s3://newbucket upload: ./file1.txt to s3://newbucket/file1.txt ``` ### 5.2 S3 → Local Download an object to a local directory: ```bash theme={null} $ aws s3 cp s3://newbucket/file1.txt /tmp/ download: s3://newbucket/file1.txt to ./tmp/file1.txt ``` ### 5.3 S3 → S3 Copy between two buckets: ```bash theme={null} $ aws s3 cp s3://bucket1/file1.txt s3://bucket2/ copy: s3://bucket1/file1.txt to s3://bucket2/file1.txt ``` *** ## 6. Deleting Objects ### 6.1 Single Object ```bash theme={null} $ aws s3 rm s3://bucket/404.html delete: s3://bucket/404.html ``` ### 6.2 Multiple Objects (Recursive) ```bash theme={null} $ aws s3 rm s3://bucket/logs/ --recursive delete: s3://bucket/logs/log1 delete: s3://bucket/logs/log2 ``` *** ## 7. Directory Operations Most S3 CLI commands support `--recursive` to process all files under a directory or prefix. ### 7.1 Copy an Entire Directory ```bash theme={null} $ aws s3 cp media/ s3://newbucket --recursive ``` ### 7.2 Move Files and Directories Use `mv` to transfer and remove the source: ```bash theme={null} # Local → S3 $ aws s3 mv file1.txt s3://newbucket move: ./file1.txt to s3://newbucket/file1.txt # S3 → Local $ aws s3 mv s3://newbucket/file1.txt /tmp/ move: s3://newbucket/file1.txt to ./tmp/file1.txt # Recursive Move $ aws s3 mv media/ s3://newbucket --recursive ``` *** ## 8. Synchronizing Directories Keep a local folder and an S3 prefix in sync. Only new or updated files transfer: ```bash theme={null} $ aws s3 sync /path/to/local/dir s3://bucket upload: home/bob to s3://bucket/home/bob upload: var/log to s3://bucket/var/log ``` Adding new files (for example, `etc/ssh`) and rerunning uploads only those: ```bash theme={null} $ aws s3 sync /path/to/local/dir s3://bucket upload: etc/ssh to s3://bucket/etc/ssh ``` *** ## Next Steps You’ve mastered the core AWS S3 CLI commands for bucket and object management. Apply these operations in scripts or CI/CD pipelines to automate your workflows. *** ## Links and References * [AWS CLI S3 Command Reference](https://docs.aws.amazon.com/cli/latest/reference/s3/) * [Amazon S3 Documentation](https://docs.aws.amazon.com/s3/) * [AWS CLI Installation Guide](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html)
