When I'm using the [rails console](http://guides.rubyonrails.org/command_line.html) I like having a `clear!` command along side the `reload!` command, so every time I launch the rails console I write

```
def clear!
   system('clear')
end

```

When I repeat behavior in my bash shell I add it to my `~/.bashrc` file. Is there a similar way for me to do this for my rails console?
