# S3cmd S3cmd is a free command line tool and client for loading, retrieving, and managing data in S3. It has over 60 command line options, including multipart uploads, encryption, incremental backup, S3 sync, ACL and metadata management, bucket size, and bucket policies (Linux, macOS). ### Configuration Install 3cmd for your distribution: * on CentOS/RHEL and Fedora: `sudo dnf install s3cmd` * on Ubuntu/Debian: `sudo apt-get install s3cmd` * on macOS using [**Brew**](https://brew.sh/): `brew install s3cmd` You can also install the latest version from [**SourceForge**](https://s3tools.org/download). ### Configuration steps Run the following command in a terminal: `s3cmd --configure`. This will guide you through the interactive installation process: 1. Enter your Access Key and Secret key. To get them, [log in to the DCD](https://docs.ionos.com/cloud/getting-started/basic-tutorials/log-in-dcd), go to **Menu** > **Storage** > **IONOS S3 Object Storage** > **Key management**. {% hint style="info" %} **Note:** Your credentials are not tied to a specific region or bucket. {% endhint %} 2. Specify the region of your bucket for `Default Region`. Example: `eu-central-2`. Please refer to the [**list of available regions**](https://docs.ionos.com/cloud/~/revisions/bM7yG7XCmGE9IxWqMpBu/managed-services/s3-object-storage/s3-endpoints). 3. Specify the endpoint for the selected region for `S3 Endpoint` from the same list. For example, `s3-eu-central-2.ionoscloud.com`. 4. Insert the same endpoint again for `DNS-style bucket+hostname:port template`. 5. Specify or skip password (press Enter) for `Encryption password`. 6. Press Enter for `Path to GPG program`. 7. Press Enter for `Use HTTPS protocol`. 8. Press Enter for `HTTP Proxy server name`. 9. Press Enter for `Test access with supplied credentials? [Y/n]`. 10. S3cmd will try to test the connection. If everything went well, save the configuration by typing `y` and pressing Enter. The configuration will be saved in the `.s3cfg` file. If you need to work with more than one region or with different providers, there is a way to set up multiple configurations. Use `s3cmd -configure --config=ionos-fra` to save the configuration for a specific location or provider. Run s3cmd with the `-c` option to override the default configuration file. For example, list the object in the bucket: ``` s3cmd -c ionos-fra ls s3://my-bucket ``` You can also specify an endpoint directly on the command line to override the default setting. The Access Key and Secret key are region-independent, so s3cmd can take them from the default configuration: ``` s3cmd --host s3-eu-south-2.ionoscloud.com ls s3://my-bucket ``` Or even specify it with an Access Key and the Secret Key: ``` s3cmd --access_key=YOUR_ACCESS_KEY --secret_key=SECRET_KEY --host s3-eu-south-2.ionoscloud.com ls s3://my-bucket ``` ### Using s3cmd with IONOS S3 Object Storage Please refer to the [**list of available endpoints**](https://docs.ionos.com/cloud/~/revisions/bM7yG7XCmGE9IxWqMpBu/managed-services/s3-object-storage/s3-endpoints) for the `--host` option. You can skip this option if you are only using the region from the configuration file. #### Sample usage * List buckets (even buckets from other regions will be listed): ``` s3cmd ls ``` * Create a bucket (the name must be unique for the whole IONOS S3 Object Storage). You need to explicitly use the `--region` option, otherwise a bucket will be created in the default `de` region: * Create the bucket `my-bucket` in the region `de` (Frankfurt, Germany): ``` s3cmd --host s3-eu-cental-1.ionoscloud.com --region=de mb s3://my-bucket ``` * Create the bucket `my-bucket` in the region `eu-cental-2` (Berlin, Germany): ``` s3cmd --host s3-eu-cental-2.ionoscloud.com --region=eu-central-2 mb s3://my-bucket ``` * Create the bucket `my-bucket` in the region `eu-south-2` (Logrono, Spain): ``` s3cmd --host s3-eu-south-2.ionoscloud.com --region=eu-south-2 mb s3://my-bucket ``` * List objects of the bucket `my-bucket`: ``` s3cmd ls s3://my-bucket ``` * Upload **filename.txt** from the current directory to the bucket `my-bucket`: ``` s3cmd put filename.txt s3://my-bucket ``` * Copy the contents of local directory `my-dir` to the bucket `my-bucket` with prefix `my-dir`: ``` s3cmd my-dir s3://my-bucket --recursive ``` * Copy all objects from `my-source-bucket` to `my-dest-bucket` excluding .zip files (or use `mv` to move objects). The command doesn’t support cross-region copying for IONOS S3 Object Storage, use [**rclone utility**](https://docs.ionos.com/cloud/~/revisions/bM7yG7XCmGE9IxWqMpBu/managed-services/s3-object-storage/s3-tools/rclone) for cross-region copying: ``` s3cmd cp s3://my-source-bucket s3://my-dest-bucket --recursive ``` * Download all the objects from the `my-bucket` bucket to the local directory `my-dir` (the directory should exist): ``` s3cmd get s3://my-bucket my-dir --recursive ``` * Synchronize a directory to S3 (checks files using size and md5 checksum): ``` s3cmd sync my-dir s3://my-bucket/ ``` * Get Cross-Origin Resource Sharing (CORS) configuration: ``` s3cmd info s3://my-bucket ``` * Set up Cross-Origin Resource Sharing (CORS) configuration: ``` s3cmd cors_rules.xml s3://my-bucket ``` **cors\_rules.xml**: ```xml http://www.MY-DOMAIN.com http://MY-DOMAIN.COM PUT POST DELETE * 3000 ETag ``` * Delete CORS from the bucket: ``` s3cmd delcors s3://my-bucket ``` * Get information about buckets or objects: * `s3cmd info s3://my-bucket` * `s3cmd info s3://my-bucket/my-object` * Generate a public URL for download that will be available for 10 minutes (600 seconds): ``` s3cmd signurl s3://my-bucket/filename.txt +600 ``` * Set up a lifetime policy for a bucket (delete objects older than 1 day): ``` s3cmd setlifecycle detete-after-one-day.xml s3://my-bucket ``` **detete-after-one-day.xml**: ```xml Delete older than 1 day Enabled 1 ``` * Encrypt and upload files. This option allows you to encrypt files before uploading, but in order to use it, you have to run `s3cmd --configure` and fill out the path to the GPG utility and the encryption password. There is no need to use special parameters to decrypt the file on downloading with `get` option as this is done automatically using the data from the configuration file. * Add or modify user-defined metadata. Use headers starting with `x-amz-meta-` and store data in the set of key-value pairs. The user-defined metadata is limited to 2 KB in size. The size of the user-defined metadata is measured by taking the sum of the number of bytes in the UTF-8 encoding of each key and value. * `s3cmd modify --add-header x-amz-meta-my_key:my_value s3://my-bucket/prefix/filename.txt` * Check the changes: ``` s3cmd info s3://my-bucket/prefix/filename.txt ``` * Delete metadata: ``` s3cmd modify --remove-header x-amz-meta-my_key s3://my-bucket/prefix/filename.txt ``` For more information, visit [**S3cmd usage**](https://s3tools.org/usage) and [**S3cmd FAQ**](https://s3tools.org/kb/index.htm).
