Redis Expire Command

Redis Key

The Redis Expire command is used to set the expiration time for a key. Once the key expires, it will no longer be available. The unit is in seconds.

Syntax

The basic syntax for the redis Expire command is as follows:

redis 127.0.0.1:6379> Expire KEY_NAME TIME_IN_SECONDS

Available Versions

= 1.0.0

Return Value

Returns 1 if the setting is successful. Returns 0 if the key does not exist or if the expiration time cannot be set for the key (for example, if you try to update the expiration time of a key in a Redis version lower than 2.1.3).

Example

First, create a key and assign a value:

redis 127.0.0.1:6379> SET runooobkey redis
OK

Set the expiration time for the key:

redis 127.0.0.1:6379> EXPIRE runooobkey 60
(integer) 1

In the above example, we set the expiration time for the key runooobkey to 1 minute. After 1 minute, the key will be automatically deleted.
