LINDEX
Syntax
LINDEX key index
- Available since:
- Redis Open Source 1.0.0
- Time complexity:
- O(N) where N is the number of elements to traverse to get to the element at index. This makes asking for the first or the last element of the list O(1).
- ACL categories:
-
@read,@list,@slow, - Compatibility:
- Redis Software and Redis Cloud compatibility
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.
