Subscribes the client to the given patterns.

Supported glob-style patterns:

* `h?llo` subscribes to `hello`, `hallo` and `hxllo`
* `h*llo` subscribes to `hllo` and `heeeello`
* `h[ae]llo` subscribes to `hello` and `hallo,` but not `hillo`

Use `\` to escape special characters if you want to match them verbatim.

Once the client enters the subscribed state it is not supposed to issue any other commands, except for additional [`SUBSCRIBE`](https://redis.io/docs/latest/commands/subscribe), [`SSUBSCRIBE`](https://redis.io/docs/latest/commands/ssubscribe), `PSUBSCRIBE`, [`UNSUBSCRIBE`](https://redis.io/docs/latest/commands/unsubscribe), [`SUNSUBSCRIBE`](https://redis.io/docs/latest/commands/sunsubscribe), [`PUNSUBSCRIBE`](https://redis.io/docs/latest/commands/punsubscribe), [`PING`](https://redis.io/docs/latest/commands/ping), [`RESET`](https://redis.io/docs/latest/commands/reset) and [`QUIT`](https://redis.io/docs/latest/commands/quit) commands.
However, if RESP3 is used (see [`HELLO`](https://redis.io/docs/latest/commands/hello)) it is possible for a client to issue any commands while in subscribed state.

For more information, see [Pub/sub](https://redis.io/docs/latest/develop/pubsub).

## Behavior change history

*   `>= 6.2.0`: [`RESET`](https://redis.io/docs/latest/commands/reset) can be called to exit subscribed state.

## Return information

{{< multitabs id="psubscribe-return-info" 
    tab1="RESP2"
