# Manage object stores using the CLI

Using the CLI, you can perform the following actions:

* [View object stores](#view-object-stores)
* [Add an object store](#add-an-object-store-bucket)
* [View object store buckets](#view-object-store-buckets)
* [Add an object store bucket](#add-an-object-store-bucket)
* [Edit an object store bucket](#edit-an-object-store-bucket)
* [List recent operations of an object store bucket](#show-recent-operations-of-an-object-store-bucket)
* [Delete an object store bucket](#delete-an-object-store-bucket)

## View object stores

**Command:** `weka fs tier obs`

This command is used to view information on all the object stores configured to the WEKA system.

{% hint style="info" %}
**Note:** Using the GUI only object-store buckets are present. Adding an object-store bucket will add it to the only `local` or `remote` object-store present. If more than one is present (such as during the time recovering from a remote snapshot), the CLI should be used.
{% endhint %}

## Edit an object store

**Command:** `weka fs tier obs update`

Use the following command line to edit an object store:

`weka fs tier obs update <name> [--new-name new-name] [--site site] [--hostname=<hostname>] [--port=<port>] [--auth-method=<auth-method>] [--region=<region>] [--access-key-id=<access-key-id>] [--secret-key=<secret-key>] [--protocol=<protocol>] [--bandwidth=<bandwidth>] [--download-bandwidth=<download-bandwidth>] [--upload-bandwidth=<upload-bandwidth>] [--max-concurrent-downloads=<max-concurrent-downloads>] [--max-concurrent-uploads=<max-concurrent-uploads>] [--max-concurrent-removals=<max-concurrent-removals>] [--enable-upload-tags=<enable-upload-tags>]`

## Edit an object store bucket

**Command:** `weka fs tier s3 update`

Use the following command line to edit an object-store bucket:

`weka fs tier s3 update <name> [--new-name=<new-name>] [--new-obs-name new-obs-name] [--hostname=<hostname>] [--port=<port> [--bucket=<bucket>] [--auth-method=<auth-method>] [--region=<region>] [--access-key-id=<access-key-id>] [--secret-key=<secret-key>] [--protocol=<protocol>] [--bandwidth=<bandwidth>] [--download-bandwidth=<download-bandwidth>] [--upload-bandwidth=<upload-bandwidth>] [--errors-timeout=<errors-timeout>] [--prefetch-mib=<prefetch-mib>] [--enable-upload-tags=<enable-upload-tags>]`
