Returns all the members of the set value stored at `key`.

This has the same effect as running [`SINTER`]({{< relref "/commands/sinter" >}}) with one argument `key`.

## Examples

{{< clients-example set="cmds_set" step="smembers" description="Foundational: Retrieve all members of a set using SMEMBERS (returns unordered collection, useful for iterating all set members)" difficulty="beginner" >}}
redis> SADD myset "Hello"
(integer) 1
redis> SADD myset "World"
(integer) 1
redis> SMEMBERS myset
1) "Hello"
2) "World"
{{< /clients-example >}}

Give these commands a try in the interactive console:

{{% redis-cli %}}
SADD myset "Hello"
SADD myset "World"
SMEMBERS myset
{{% /redis-cli %}}
