It is composed of subcommands that are documented +separately. The general form is: + + PUBSUB <subcommand> ... args ... + +# PUBSUB CHANNELS [pattern] + +Lists the currently _active channels_. An active channel is a Pub/Sub channel +with one or more subscribers (not including clients subscribed to patterns). + +If no `pattern` is specified, all the channels are listed, otherwise if pattern +is specified only channels matching the specified glob-style pattern are listed. + +@return + +@array-reply: a list of active channels, optionally matching the specified +pattern. + +# `PUBSUB NUMSUB [channel-1 ... channel-N]` + +Returns the number of subscribers (not counting clients subscribed to patterns) +for the specified channels. + +@return + +@array-reply: a list of channels and number of subscribers for every channel. +The format is channel, count, channel, count, ..., so the list is flat. The +order in which the channels are listed is the same as the order of the channels +specified in the command call. + +Note that it is valid to call this command without channels. In this case it +will just return an empty list. + +# `PUBSUB NUMPAT` + +Returns the number of subscriptions to patterns (that are performed using the +`PSUBSCRIBE` command). Note that this is not just the count of clients +subscribed to patterns but the total number of patterns all the clients are +subscribed to. + +@return + +@integer-reply: the number of patterns all the clients are subscribed to. |
