AWS S3 CLI Commands Cheat Sheet: Complete Guide

Working with AWS S3 can be daunting, especially when it comes to managing your buckets and objects from the command line. Fortunately, the AWS S3 CLI provides a range of commands to help you do just that.

The AWS S3 CLI is a powerful tool that allows you to perform a variety of tasks, including creating and deleting buckets, uploading and downloading files, and setting permissions.

To get started, you'll need to install the AWS CLI on your machine. Once installed, you can use the `aws s3` command to access the S3 CLI.

The S3 CLI commands are organized into several categories, including bucket operations, object operations, and bucket policy operations.

AWS S3 CLI is a powerful tool for managing your S3 bucket and objects. It's essential to understand the basic terms and syntax before diving into the CLI commands.

A bucket is the top-level container where you store your objects. Objects can be any item, such as files or folders, stored in your S3 bucket.

You can create and manage your S3 bucket and objects using the aws s3 CLI command. The basic syntax is quite simple, and you can add multiple arguments like –region, –recursive, and –profile to customize your commands.

Here are some basic CLI commands you can use with S3: cp (copy)ls (list)mb (make bucket)mv (move)presign (generate presigned URL)rb (remove bucket)rm (remove object)sync (sync objects)website (enable website hosting)

You can use these commands on a single object or all objects under a bucket or prefix by using the –recursive option.

The AWS S3 CLI Commands Cheat Sheet is a must-have for anyone working with Amazon S3. It's a collection of essential commands that can be used to perform various tasks, from creating and listing buckets to uploading and downloading files.

To create a bucket, you can use the `aws s3 mb` command, which creates a bucket in the default region. For example, `aws s3 mb s3://madhu-cli-test-bucket` creates a bucket named `madhu-cli-test-bucket`.

Here's a list of some of the most commonly used AWS S3 CLI commands:

To list all buckets, use the `aws s3 ls` command. To list the objects in a specific bucket, use the `aws s3 ls` command followed by the bucket name, like `aws s3 ls s3://madhue-portfolio.com`.

To upload a file to a bucket, use the `aws s3 cp` command, followed by the source file path and the destination bucket path. For example, `aws s3 cp index.html s3://madhu-cli-test-bucket`.

To download a file from a bucket, use the `aws s3 cp` command, followed by the source bucket path and the destination file path. For example, `aws s3 cp s3://madhu-cli-test-bucket/index.html test.html`.

You can also use the `aws s3 presign` command to generate a presigned URL for an object, which can be used to grant access to the object without sharing the access key. For example, `aws s3 presign s3://website-test-cli/index.html` generates a presigned URL for the `index.html` object in the `website-test-cli` bucket.

To copy files to S3, you can use the s3 cp command, which allows you to copy one object or multiple files to and from an S3 bucket.

You can use s3 cp to copy objects from one S3 bucket to another, or from a local file system to an S3 bucket.

The s3 cp command is very versatile and can be used to copy all objects in a specific bucket, such as s3://bucket-name/example, into another bucket.

Ideally, you can make your own combination of source and destination and copy objects to or from an S3 bucket using the s3 cp command.

To move an object or file, you can use the s3 mv command, which moves a local file or S3 object to another location locally or in S3.

Managing files in S3 is a breeze with the right commands. You can copy files to and from an S3 bucket using the s3 cp command.

To move files, use the s3 mv command, which moves a local file or S3 object to another location locally or in S3. This is a great way to reorganize your files without having to download and reupload them.

Deleting files is also straightforward. Use the s3 rm command to delete a file from an S3 bucket. If you want to delete all files, including those in subfolders, add the –recursive option.

You can copy multiple objects from one S3 bucket to another using the s3 cp command.

To copy all objects in a specific bucket, you can use the s3 cp command with the source and destination buckets specified.

Ideally, you can make your own combination of source and destination and copy objects to or from an S3 bucket.

This flexibility allows you to customize your file transfers according to your needs.

You can use the s3 cp command to copy objects from one S3 bucket to another, or even from an S3 bucket to a local directory.

In fact, you can copy multiple objects from one S3 bucket to another using the s3 cp command, making it a convenient way to manage your files in S3.

To delete a file from an S3 bucket, you can use the s3 rm command. This command is straightforward and easy to use.

You can delete a file from an S3 bucket using the s3 rm command. The syntax looks like this: s3 rm command.

You can delete all files from a bucket using the s3 rm command with the –recursive option. This will delete all objects, even those in subfolders.

The –recursive option allows you to delete all objects in a bucket, including those in subfolders. This is useful when you need to clean up a large bucket quickly.

To delete all files from a bucket, simply use the s3 rm command with the –recursive option, and AWS will take care of the rest.

To configure the S3 CLI, you'll need to set up your AWS credentials. This can be done using the AWS CLI configuration command, aws configure.

The aws configure command will prompt you to enter your AWS access key ID, secret access key, default region name, and default output format.

You can also specify a profile name to use for your AWS credentials. This is useful if you have multiple AWS accounts or want to use different credentials for different projects.

Make sure to store your AWS credentials securely, as they grant access to your AWS account.

The AWS S3 CLI is a powerful tool, and once you've mastered the basics, it's time to take it to the next level with some advanced tasks.

You can use the `aws s3 sync` command to synchronize files and directories between your local machine and an S3 bucket, but did you know you can also use it to synchronize files across multiple buckets?

Synchronizing files across multiple buckets can be a huge time-saver, especially if you have a lot of data to manage.

To use `aws s3 sync` with multiple buckets, simply specify the source and destination buckets using the `--source` and `--destination` options.

The `aws s3 cp` command is another powerful tool for transferring files between your local machine and an S3 bucket, and it also supports the `--recursive` option to transfer entire directories.

The `--recursive` option can save you a lot of time and effort when transferring large directories.

You can also use the `aws s3 ls` command to list the objects in an S3 bucket, and the `--human-readable` option to display the object sizes in a more readable format.

The `--human-readable` option is especially useful when you have a lot of large objects in your bucket.

The `aws s3 rm` command can be used to delete objects from an S3 bucket, but be careful when using it, as it permanently deletes the objects and can't be undone.

Make sure to specify the correct bucket and object names when using `aws s3 rm` to avoid deleting the wrong objects.

Before diving into the S3 CLI commands, it's essential to understand some crucial terms.

You need to know what S3 CLI is, which stands for Amazon S3 Command Line Interface.

The S3 CLI is a tool that allows you to interact with Amazon S3 using commands in your terminal.

To use the S3 CLI, you need to have the AWS CLI installed on your MacOS, as it's MacOS specific.
