bashANYawss3download
bash
aws s3 cp s3://my-bucket/backups/db.dump ./db.dumpDownloads a single object to a local path.
bashANYawss3recursive
bash
aws s3 cp ./dist s3://my-bucket/site/ --recursiveFrequently used for static site and artifact uploads.
bashANYawss3sync
bash
aws s3 sync ./public s3://my-bucket/public/Sync compares source and destination to transfer only needed changes.
bashANYawss3syncdanger

bashANYawss3move
bash
aws s3 mv s3://my-bucket/tmp/file.txt s3://my-bucket/archive/file.txtUnder the hood this is effectively copy plus delete.

Low-level bucket management with `aws s3api`.
bashANYawss3apibucket
bash
aws s3api create-bucket --bucket my-bucket --region us-west-2 --create-bucket-configuration LocationConstraint=us-west-2Use `s3api` when you need explicit API-level control.
bashANYawss3apibuckethead
bash
aws s3api head-bucket --bucket my-bucketCommon in scripts that verify access or existence.
bashANYawss3apibucketregion
bash
aws s3api get-bucket-location --bucket my-bucketUseful when troubleshooting region mismatch issues.
bashANYawss3apiversioning
bash
aws s3api put-bucket-versioning --bucket my-bucket --versioning-configuration Status=EnabledVersioning protects against accidental overwrites and deletes.
bashANYawss3apiversioning
bash
aws s3api get-bucket-versioning --bucket my-bucketUse this to confirm whether versioning is enabled or suspended.
bashANYawss3apiencryption
bash
aws s3api put-bucket-encryption --bucket my-bucket --server-side-encryption-configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}'Sets default encryption so new uploads inherit the policy automatically.
bashANYawss3apiencryption
bash
aws s3api get-bucket-encryption --bucket my-bucketUseful in compliance and audit scripts.
bashANYawss3apisecurity
bash
aws s3api put-public-access-block --bucket my-bucket --public-access-block-configuration BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=trueCommon baseline security setting for private buckets.

bash
aws s3api put-bucket-policy --bucket my-bucket --policy file://bucket-policy.jsonUse policy files for maintainable, reviewable access control.
bashANYawss3apibucketdelete
bash
aws s3api delete-bucket --bucket my-bucketThe bucket must be empty before deletion succeeds.
S3API Object Commands
Low-level object inspection and manipulation.
bashANYawss3apiput-object
bash
aws s3api put-object --bucket my-bucket --key docs/readme.txt --body ./README.mdUseful when you need API-level options not exposed in high-level `aws s3` commands.
bashANYawss3apiget-object
bash
aws s3api get-object --bucket my-bucket --key backups/db.dump ./db.dumpCan expose metadata and range options in low-level workflows.
bashANYawss3apihead-object
bash
aws s3api head-object --bucket my-bucket --key backups/db.dumpA very common way to confirm size, etag, storage class, and metadata.
bashANYawss3apicopy-object
bash
aws s3api copy-object --bucket my-bucket --copy-source source-bucket/path/file.txt --key copies/file.txtUseful when you need metadata directives or encryption options.
bashANYawss3apidelete-object
bash
aws s3api delete-object --bucket my-bucket --key tmp/file.txtUseful in scripts that already use low-level S3 API commands.
bashANYawss3apiversions
bash
aws s3api list-object-versions --bucket my-bucket --prefix app/Useful when recovering or auditing previous object states.
bashANYawss3apiversionsdelete
bash
aws s3api delete-object --bucket my-bucket --key app/config.json --version-id 3Lg..exampleTargets one specific version instead of the current latest version only.
bashANYawss3presign
