Discord only directive to post in specific channel

I'd like a directive for custom commands where it'll tell the bot where to post a response. For example, I have a #bots-command channel where I put all my commands, but I want the bot to notify people in the general channel. Here's an example:

In #bots-command
!startgiveaway

Response in #general
