LINDEX

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

redis> LPUSH mylist "World" (integer) 1 redis> LPUSH mylist "Hello" (integer) 2 redis> LINDEX mylist 0 "Hello" redis> LINDEX mylist -1 "World" redis> LINDEX mylist 3 (nil)
