Redis

LINDEX key index

Returns the element at index index in the list stored at key. The index is zero-based, so 0 means the first element, 1 the second element and so on. Negative indices can be used to designate elements starting at the tail of the list. Here, -1 means the last element, -2 means the penultimate and so forth.

When the value at key is not a list, an error is returned.

Return value

Bulk string reply: the requested element, or nil when index is out of range.

Examples

(integer) 1
redis>  LPUSH mylist "Hello"
(integer) 2
redis>  LINDEX mylist 0
"Hello"
redis>  LINDEX mylist -1
