一个关于cdoldvalidatecmd的问题

If this cvar is not blank, C-D will execute it every time a player tries to validated using an old challenge. C-D will automatically append a "\n" to this command. Players will usually only fail to validate once. You may have one "%d" in your command. The "%d" will be replaced with the validating player's id. For example:
cdoldvalidatecmd "kick #%d"

如果我同意他老的CD，我用什么命令去修改上面的命令来实现
