# RPOPLPUSH

> Pop from tail and push to head.

<Warning>
  Prefer [`LMOVE`](/docs/redis/commands/list/lmove) with `RIGHT` and `LEFT` in new code: `LMOVE <source> <destination> RIGHT LEFT`.
</Warning>

Use `RPOPLPUSH` to atomically move an element from the tail of one list to the head of another, returning the element.

If the source is empty nothing happens and the reply is null. Source and destination may be the same key, which rotates the list: the tail element becomes the new head, so repeated calls cycle through a list of items forever, a handy pattern for round-robin scheduling.

[`LMOVE`](/docs/redis/commands/list/lmove) does the same thing but lets you choose both ends, and [`BRPOPLPUSH`](/docs/redis/commands/list/brpoplpush) is the blocking form.

## Syntax

```redis theme={"system"}
RPOPLPUSH <source> <destination>
```

## Arguments

| Argument        | Required | Repeatable | Description                    |
| --------------- | -------- | ---------- | ------------------------------ |
| `<source>`      | Yes      | No         | Redis key used as source.      |
| `<destination>` | Yes      | No         | Redis key used as destination. |

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply                                         |
| -------- | --------------------------------------------- |
| RESP2    | Bulk string or Null bulk string or null array |
| RESP3    | Bulk string or Null                           |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
</Note>

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
