PSUBSCRIBE pattern [pattern ...]
Available since:
Time complexity:
O(N) where N is the number of patterns to subscribe to.
ACL categories:
@pubsub, @slow,

Subscribes the client to the given patterns.

Supported glob-style patterns:

  • h?llo subscribes to hello, hallo and hxllo
  • h*llo subscribes to hllo and heeeello
  • h[ae]llo subscribes to hello and hallo, but not hillo

Use \ to escape special characters if you want to match them verbatim.

Once the client enters the subscribed state it is not supposed to issue any other commands, except for additional SUBSCRIBE, SSUBSCRIBE, PSUBSCRIBE, UNSUBSCRIBE, SUNSUBSCRIBE, PUNSUBSCRIBE, PING, RESET and QUIT commands. However, if RESP3 is used (see HELLO) it is possible for a client to issue any commands while in subscribed state.

For more information, see Pub/sub.

Behavior change history

  • >= 6.2.0: RESET can be called to exit subscribed state.


When successful, this command doesn't return anything. Instead, for each pattern, one message with the first element being the string psubscribe is pushed as a confirmation that the command succeeded.
