You can also use negative indices, where -1 represents the last element of the list, -2 represents the second-to-last element, and so on. ### Syntax The basic syntax for the Redis Ltrim command is: redis 127.0.0.1:6379> LTRIM KEY_NAME START STOP ### Available Since >= 1.0.0 ### Return Value Returns OK if the command was executed successfully. ### Example redis 127.0.0.1:6379> RPUSH mylist "hello"(integer) 1 redis 127.0.0.1:6379> RPUSH mylist "hello"(integer) 2 redis 127.0.0.1:6379> RPUSH mylist "foo"(integer) 3 redis 127.0.0.1:6379> RPUSH mylist "bar"(integer) 4 redis 127.0.0.1:6379> LTRIM mylist 1 -1 OK redis 127.0.0.1:6379> LRANGE mylist 0 -11) "hello"2) "foo"3) "bar" [!(#) Redis Lists](#)
