# 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`](https://redis.io/docs/latest/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 ``` ## Return information {{< multitabs id="httl-return-info" tab1="RESP2" tab2="RESP3" >}} * [Array reply](../../develop/reference/protocol-spec#arrays). For each field: - [Integer reply](../../develop/reference/protocol-spec#integers): `-2` if no such field exists in the provided hash key, or the provided key does not exist. - [Integer reply](../../develop/reference/protocol-spec#integers): `-1` if the field exists but has no associated expiration set. - [Integer reply](../../develop/reference/protocol-spec#integers): the TTL in seconds. -tab-sep- * [Array reply](../../develop/reference/protocol-spec#arrays).
