$this->stdin->read(); will use readline if the system is detected to support it. In linux, you will be able to use the left and right arrow keys to edit the current line, use the up and down keys to navigate history, press ^U to delete the entire line, etc. Before this, using arrow keys in linux will just spam characters like ^[[C^[[A^[[D^[[C^[[A^. Useful for "Console/cake console"
