This repository contains shell scripts to manage Amazon S3 buckets and objects using AWS CLI.

Source Code: https://github.com/SarinHem/AWS-Lab.git

Scripts cover bucket creation, deletion, uploading files, listing buckets/objects, syncing files, and backup file renaming.

---

Prerequisites

• AWS CLI installed and configured (aws configure) with appropriate IAM permissions.
• Bash shell environment (Linux, macOS, WSL).
• Network access to AWS.

Usage Details

Create Bucket

./create-bucket <bucket-name>

Delete Bucket

./delete-bucket <bucket-name> [--force]

--force empties the bucket before deleting.

Upload File (Put Object)

./put-object <bucket-name> <local-file> [s3-key]

Uploads file to S3 bucket. If s3-key is omitted, filename is used.

List Buckets

./list-bucket

List Objects

./list-object <bucket-name> [prefix]

Sync Directory to S3

./sync <local-dir> <bucket-name> [s3-prefix]

Syncs local folder to bucket and deletes extra files in S3.

Backup File Rename

./backup/file_got_rename

Refer to script comments for details.

Notes

• All scripts assume AWS region ap-southeast-1 (Singapore). Adjust inside scripts if needed.
• Make sure scripts have execute permission:

  chmod +x ./create-bucket ./delete-bucket ./put-object ./list-bucket ./list-object ./sync ./backup/file_got_rename
  

• Ensure your AWS CLI credentials have required permissions.

---

Troubleshooting

• Test AWS credentials:

  aws sts get-caller-identity
  

• Use --dryrun option inside sync script if supported for preview.
• Bucket names must be globally unique.
