Redis EXISTS Command

Redis key

The Redis EXISTS command is used to check whether a given key exists.

Syntax

The basic syntax of the redis EXISTS command is as follows:

redis 127.0.0.1:6379> EXISTS KEY_NAME

Available Versions

>= 1.0.0

Return Value

Returns 1 if the key exists, otherwise returns 0.

Examples

redis 127.0.0.1:6379> EXISTS example-new-key
(integer) 0

Now let's create a key named example-new-key and assign a value, then use the EXISTS command.

redis 127.0.0.1:6379> set example-new-key newkey
OK
redis 127.0.0.1:6379> EXISTS example-new-key
(integer) 1
redis 127.0.0.1:6379>
