You can read more about them below. ### About Prefix Commands Prefix commands are basically commands that have a symbol infront of them. Instead of sending them via Discord like [slash commands](/infinitybot-docs/guides/infinitybot-guides/command-guides/how-slash-commands-work.md) (`/`), you send them directly in chat. InfinityBot uses `!` as prefix. You can get a list with all prefix commands you can use by sending `!prefix` in chat or by visiting [the prefix page](/infinitybot-docs/server-tools/prefix-commands.md).

### Setup #### Custom Prefix You can set a custom prefix with the `!set-prefix` command. #### Command Channel You can select a command channel with the `!cmnd-channel` command. Users will then only be able to use prefix commands in that channel. ### Prefix Command Options Prefix commands can also have options. These can be added after the command, for example to ban a user, the option would be the user and the reason of the ban. This would be the template of the ban command: `!ban @user reason` This would be the way you use it in a channel: `!ban @knight spamming`, replacing the options.

#### Reply Option You can also target a message with prefix commands by replying to it. This can only be done if you need to target a message, for example when using the `!pin` command.
