In Redis, the SRANDMEMBER command returns one or more random members from the set value store at the specified key.
If you want to remove the random member/s from the set, use the SPOP command.

Redis SPOP Command Explained
In Redis, the SPOP command removes and returns one or more random members from the set value store at the specified key.
This command is similar to the SRANDMEMBER command in that it returns one or more random members from a set, but SPOP removes it, whereas SRANDMEMBER doesn’t.
Redis SMOVE Command Explained
In Redis, the SMOVE command moves a member of a set from one key to another. In other words, the member is removed from the source set and added to the destination set.
Redis SMEMBERS Command Explained
In Redis, the SMEMBERS command returns all members of a given set. We specify the key name of the set when we call the command.
Redis SMISMEMBER Command Explained
In Redis, we can use the SMISMEMBER command to find out whether one or more members are in a given set. It’s similar to the SISMEMBER command, except that it allows us to check more than one member at a time.
The SMISMEMBER command was introduced in Redis 6.2.0.
Redis SISMEMBER Command Explained
In Redis, we can use the SISMEMBER command to find out whether or not a set contains a given member.
Redis SINTERCARD Command Explained
In Redis, the SINTERCARD command returns the cardinality of the set which would result from the intersection of all the given sets. It’s similar to SINTER, but instead of returning the result set, it returns just the cardinality of the result.
The SINTERCARD command was introduced in Redis 7.0.0.
Redis SINTERSTORE Command Explained
In Redis, the SINTERSTORE command is the same as the SINTER command, except that it stores the result in the specified key, instead of returning it.
It stores the members of the set resulting from the intersection of all the given sets.
If the destination key already exists, it’s overwritten. If it doesn’t exist, it’s created and the resulting members are added to it.

Redis SDIFFSTORE Command Explained
In Redis, the SDIFFSTORE command works just like the SDIFF command, except that instead of returning the result, it stores it in the key that we specify. The destination key will then hold the members of the set resulting from the difference between the first set and all the successive sets.
