LPUSHX

Usage:

LPUSHX key element [ element ...]

Complexity:

O(1) for each element added, so O(N) to add N elements when the command is called with multiple arguments.

Since:

2.2.0

Inserts specified values at the head of the list stored at key, only if key already exists and holds a list. In contrary to LPUSH, no operation will be performed when key does not yet exist.

Examples

LPUSH mylist "World"
LPUSHX mylist "Hello"
LPUSHX myotherlist "Hello"
LRANGE mylist 0 -1
LRANGE myotherlist 0 -1
