In this tutorial, we will learn about how to get the names of all fields contained in the hash value stored at a key, by using a COMMAND – HKEYS in redis-cli.

Empty list is returned, if key does not exist and error is returned, if key exist but value stored at the key is not of hash datatype. The syntax of redis HKEYS command is as follows :-

Syntax :- 

redis host:post> HKEYS <keyname>

Output :- 

- (array) reply, representing the list of fields in the hash.
- Empty list, if key does not exist.
- Error, if key exist and value stored at the key is not a hash.
