RPOP key [count]

Available since 1.0.0.

Time complexity: O(N) where N is the number of elements returned

Removes and returns the last elements of the list stored at key.

By default, the command pops a single element from the end of the list. When provided with the optional count argument, the reply will consist of up to count elements, depending on the list's length.

*Return value

When called without the count argument:

Bulk string reply: the value of the last element, or nil when key does not exist.

When called with the count argument:

Array reply: the values of the last elements, or nil when key does not exist.

*History

  • >= 6.2: Added the count argument.
