In this tutorial, we will learn about how to delete one or more specified elements from a sorted set value stored at a key. For this we will use a COMMAND – ZREM in redis-cli. 

This command, deletes one or more specified elements from the sorted set stored at the specified key. Specified members that are not present in the sorted set are ignored. Error is returned, if key exist but value stored at the key is not of sorted set datatype. The syntax of redis ZREM command is as follows :- 

Syntax :- 

redis host:post> ZREM <keyname> <element> [ element ]

Output :- 

- (integer) representing number of elements deleted from the sorted set, excluding non existing members.
