Pops one or more elements from the first non-empty list key from the list of provided key names.

`LMPOP` and [`BLMPOP`](https://redis.io/docs/latest/commands/blmpop) are similar to the following, more limited, commands:

- [`LPOP`](https://redis.io/docs/latest/commands/lpop) or [`RPOP`](https://redis.io/docs/latest/commands/rpop) which take only one key, and can return multiple elements.
- [`BLPOP`](https://redis.io/docs/latest/commands/blpop) or [`BRPOP`](https://redis.io/docs/latest/commands/brpop) which take multiple keys, but return only one element from just one key.

See [`BLMPOP`](https://redis.io/docs/latest/commands/blmpop) for the blocking variant of this command.

Elements are popped from either the left or right of the first non-empty list based on the passed argument.
The number of returned elements is limited to the lower between the non-empty list's length, and the count argument (which defaults to 1).

## Examples


LMPOP 2 non1 non2 LEFT COUNT 10
LPUSH mylist "one" "two" "three" "four" "five"
LMPOP 1 mylist LEFT
LRANGE mylist 0 -1
LMPOP 1 mylist RIGHT COUNT 10
LPUSH mylist "one" "two" "three" "four" "five"
LPUSH mylist2 "a" "b" "c" "d" "e"
LMPOP 2 mylist mylist2 right count 3
LRANGE mylist 0 -1
LMPOP 2 mylist mylist2 right count 5
LMPOP 2 mylist mylist2 right count 10
EXISTS mylist mylist2

One of the following:
