- Usage:
-
LPUSH 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:
- 1.0.0
Insert all the specified values at the head of the list stored at key.
If key does not exist, it is created as empty list before performing the push
operations.
When key holds a value that is not a list, an error is returned.
It is possible to push multiple elements using a single command call just
specifying multiple arguments at the end of the command.
Elements are inserted one after the other to the head of the list, from the
leftmost element to the rightmost element.
So for instance the command LPUSH mylist a b c will result into a list
containing c as first element, b as second element and a as third element.

127.0.0.1:6379> LPUSH mylist "hello"
(integer) 2
127.0.0.1:6379> LRANGE mylist 0 -1
1) "hello"
2) "world"
