Reading a private message

[enesbakis]

The channel can do how a special command is executed in the message area.

Ex: / ban nick 3600

I need to read the channel message area

The / annotated commands in the chat section are not made for query bots, they are made for plugins and LUA scripts.
In order to read a channel message, the bot has to be inside the channel and must subscribe to the channel message event (refer to the documentation).
As far as I know you can subscribe to channel id 0, which stands for the whole server, but I think it can only receive events like people moving through the channels, but no messages.

Short story, write a clientside LUA script or C / C++ plugin to support chat commands. And they are usually only for you.

EDIT: (Because the title means something different than the question)
You can of course always subscribe to the private messages, and receive messages from clients sent directly to the query bot.
