Introduction

In this article, we will provide a step-by-step guide on how to list S3 buckets using the AWS Command Line Interface (CLI). The AWS CLI offers a command-line interface that allows you to interact with various AWS services, including Amazon S3. By following the instructions outlined below, you will be able to efficiently list all your S3 buckets.

Throughout this guide, we will also highlight additional options and parameters that can be utilized to further customize and enhance your S3 bucket listing experience. Feel free to refer to the AWS CLI documentation for a comprehensive list of available options.

By the end of this guide, you will have the knowledge and tools necessary to efficiently manage your S3 buckets from the command line interface, empowering you to streamline your workflow and effectively leverage the power of AWS CLI.

Prerequisites

Before we start listing S3 buckets using AWS CLI, ensure that you have the following prerequisites in place:

  1. AWS CLI Installation: Make sure you have AWS CLI installed and configured on your local machine. If you haven’t done this yet, refer to the official AWS CLI documentation for installation instructions specific to your operating system.
  2. AWS Access Key and Secret Access Key: Obtain your AWS Access Key and Secret Access Key. These credentials will be used for authentication and authorization while accessing AWS services, including S3. If you don’t have these credentials yet, you can generate them from the AWS Management Console.

Listing S3 Buckets using AWS CLI

Now, let’s dive into the steps to list S3 buckets using the AWS CLI:

  1. Open your preferred terminal or command prompt window.
  2. Run the following command to list all S3 buckets:
 aws s3 ls

This command will query the AWS CLI to retrieve a list of all S3 buckets associated with your AWS account. The output will display the bucket names, creation dates, and other relevant information.

(Optional) Filter buckets based on specific criteria

Filter buckets by a particular region

Use the --region parameter followed by the desired region. For example:

aws s3 ls --region us-east-1

Filter buckets based on a specific profile configured in your AWS CLI

Use the --profile parameter followed by the profile name. For example:

aws s3 ls --profile myprofile

Filter buckets by a specific prefix

Use the --prefix parameter followed by the prefix value. For example:

aws s3 ls --prefix myfolder/

Filter buckets based on a specific delimiter

Use the --delimiter parameter followed by the delimiter value. For example:

aws s3 ls --delimiter /

Sorting the bucket list

If you want to sort the list of S3 buckets in a specific order, you can use the --query parameter along with the sort_by() function. For example:

aws s3 ls --query "sort_by(Contents, &Key)"

This command will sort the list of S3 buckets based on the bucket names in ascending order.

Displaying a limited number of results

If you have a large number of S3 buckets and you only want to display a limited number of results, you can use the --page-size parameter followed by the desired number of results. For example:

aws s3 ls --page-size 10

This command will display only the first 10 S3 buckets in the list.

Filtering buckets by creation date

If you want to filter the S3 buckets based on their creation date, you can use the --query parameter along with a specific date range. For example, to list buckets created after a certain date:

aws s3 ls --query "Buckets[?CreationDate >=2-01-01']"

The aws s3 ls command also accepts other options and parameters for advanced filtering and customization. Refer to the AWS CLI documentation for a comprehensive list of available options.
