HTTL

Returns the remaining TTL (time to live) of a hash key's field(s) that have a set expiration. This introspection capability allows you to check how many seconds a given hash field will continue to be part of the hash key.

See also the [HPTTL]({{< relref "/commands/hpttl" >}}) command that returns the same information with millisecond resolution.

Example

redis> HTTL no-key FIELDS 3 field1 field2 field3
(nil)
redis> HSET mykey field1 "hello" field2 "world"
(integer) 2
redis> HEXPIRE mykey 300 FIELDS 2 field1 field3
1) (integer) 1
2) (integer) -2
redis> HTTL mykey FIELDS 3 field1 field2 field3
1) (integer) 283
2) (integer) -1
3) (integer) -2
