<para>The OpenStack Object Storage service provides the
|
|
<command>swift</command> client, which is a command-line
|
|
interface (CLI). Use this client to list objects and containers,
|
|
upload objects to containers, and download or delete objects from
|
|
containers. You can also gather statistics and update metadata for
|
|
accounts, containers, and objects.</para>
|
|
<para>This client is based on the native swift client library,
|
|
<literal>client.py</literal>, which seamlessly re-authenticates
|
|
if the current token expires during processing, retries operations
|
|
multiple times, and provides a processing concurrency of
|
|
10.</para>
