The `tctl cluster` command enables [Temporal Cluster](/temporal-service) operations.

- [tctl cluster health](#health)

## get-search-attributes

The `tctl cluster get-search-attributes` command lists all [Search Attributes](/search-attribute) that can be used in the `--query` modifier of the [`tctl workflow list`](/tctl-v1/workflow#list) command and the `--search_attr_key` and `--search_attr_value` modifiers of the [`tctl workflow run`](/tctl-v1/workflow#run) and [`tctl workflow start`](/tctl-v1/workflow#start) commands.

**Example:**

```bash
tctl cluster get-search-attributes
```

The command has no modifiers.
