UNLINK removes the given keys and returns how many of them existed. It gives the same result and the same keyspace events as DEL, so clients written for Redis that prefer UNLINK for large values work unchanged. Missing keys are ignored, and several keys are removed together.

Return value

Section titled “Return value”
Case RESP2 RESP3
Always Integer: the number of keys removed Integer

Examples

Section titled “Examples”
127.0.0.1:6379> SET cache:page "<html>...</html>"
OK
127.0.0.1:6379> UNLINK cache:page cache:other
(integer) 1

Compatibility

Section titled “Compatibility”

Same reply as Redis 7 and Valkey 8.
