{{< note >}}
This command's behavior varies in clustered Redis environments. See the [multi-key operations]({{< relref "/develop/using-commands/multi-key-operations" >}}) page for more information.
{{< /note >}}


This command is equal to [`SINTER`]({{< relref "/commands/sinter" >}}), but instead of returning the resulting set,
it is stored in `destination`.

If `destination` already exists, it is overwritten.

## Examples

{{% redis-cli %}}
SADD key1 "a"
SADD key1 "b"
SADD key1 "c"
SADD key2 "c"
SADD key2 "d"
SADD key2 "e"
SINTERSTORE key key1 key2
SMEMBERS key
{{% /redis-cli %}}
