<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>
