What is

The CLI tool "cls3" is to CLear Amazon S3 Buckets(AWS).

It empties (so deletes all objects and versions/delete-markers in) S3 Buckets or deletes the buckets themselves.

This tool allows you to search for bucket names and empty or delete multiple buckets.

Features

Bucket deletion option

Initially, the tool was intended to "empty the bucket", but since I was going to go through the trouble, I also added an option (-f|--force) to "delete the bucket as well".

Search for bucket names and delete multiple buckets

As described below (Interactive Mode), you can search for bucket names and delete or empty multiple buckets at once.

Cross-region

In deleting multiple buckets, you can delete them all at once, even if they are in multiple regions.

Versioning

Even if versioning is turned on, you can empty it just as if it were turned off. Therefore, you can use it without being aware of the versioning settings.

Deletion of old version objects only

The -o | --oldVersionsOnly option allows you to delete only old versions and all delete-markers without new versions and a bucket itself.

So you can retain the latest version objects only.

This option cannot be specified with the -f | --force option.

Number of objects that can be deleted

The delete-objects API provided by the CLI and SDK has a limit of "the number of objects that can be deleted in one command is limited to 1000", but This tool has no limit on the number.

Retry on 503 error

When there are tens of thousands of objects, a SlowDown error (503 error) may occur on the S3 api side in rare cases when deleting them all at once using the CLI or SDK.

When this occurs, cls3 responds by adding a mechanism that waits a few seconds and retries automatically several times.

Interactive Mode

BucketName Selection

In the interactive mode(-i option), you can search bucket names and select buckets.

It is designed to be searchable and deletable across regions, so it can be used without being region-aware.

It can be empty.

❯ cls3 -i
Filter a keyword of bucket names: test-goto

Then you select bucket names in the UI.

? Select buckets.
  [Use arrows to move, space to select, <right> to all, <left> to none, type to filter]
