Removes the first count occurrences of elements equal to value from the list stored at key. The count argument influences the operation in the following ways:

  • count > 0: Remove elements equal to value moving from head to tail.
  • count < 0: Remove elements equal to value moving from tail to head.
  • count = 0: Remove all elements equal to value.

For example, LREM list -2 "hello" will remove the last two occurrences of "hello" in the list stored at list.

Note that non-existing keys are treated like empty lists, so when key does not exist, the command will always return 0.

@return

@integer-reply: the number of removed elements.

@examples

RPUSH mylist "hello"
RPUSH mylist "hello"
RPUSH mylist "foo"
RPUSH mylist "hello"
LREM mylist -2 "hello"
LRANGE mylist 0 -1
