# aws CLI

**Last reviewed:**  almost 4 years ago 

You must [generate an Access Key](https://developers.cloudflare.com/r2/api/tokens/) before getting started. All examples will utilize `access_key_id` and `access_key_secret` variables which represent the **Access Key ID** and **Secret Access Key** values you generated.

  
With the [aws ↗](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) CLI installed, you may run [aws configure ↗](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html#cli-configure-quickstart-config) to configure a new profile. You will be prompted with a series of questions for the new profile's details.

Terminal window

```

aws configure


```

```

AWS Access Key ID [None]: <ACCESS_KEY_ID>

AWS Secret Access Key [None]: <SECRET_ACCESS_KEY>

Default region name [None]: auto

Default output format [None]: json


```

The `region` value can be set to `auto` since it is required by the SDK but not used by R2.

You may then use the `aws` CLI for any of your normal workflows.

Terminal window

```

# Provide your Cloudflare account ID

aws s3api list-buckets --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com

# {

#     "Buckets": [

#         {

#             "Name": "my-bucket",

#             "CreationDate": "2022-05-18T17:19:59.645000+00:00"

#         }

#     ],

#     "Owner": {

#         "DisplayName": "134a5a2c0ba47b38eada4b9c8ead10b6",

#         "ID": "134a5a2c0ba47b38eada4b9c8ead10b6"

#     }

# }


aws s3api list-objects-v2 --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com --bucket my-bucket

# {

#     "Contents": [

#         {

#             "Key": "ferriswasm.png",

#             "LastModified": "2022-05-18T17:20:21.670000+00:00",

#             "ETag": "\"eb2b891dc67b81755d2b726d9110af16\"",

#             "Size": 87671,

#             "StorageClass": "STANDARD"

#         }

#     ]

# }


```

## Generate presigned URLs

You can also generate presigned links which allow you to share public access to a file temporarily.

Terminal window

```

# You can pass the --expires-in flag to determine how long the presigned link is valid.

aws s3 presign --endpoint-url https://<ACCOUNT_ID>.r2.cloudflarestorage.com  s3://my-bucket/ferriswasm.png --expires-in 3600

# https://<ACCOUNT_ID>.r2.cloudflarestorage.com/my-bucket/ferriswasm.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=<credential>&X-Amz-Date=<timestamp>&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=<signature>
