Chapter 13. Controlling Devices > Using Redirection Commands

Using Redirection Commands

DOS uses three standard devices: one for input, one for output, and one for errors. The main input/output device is the console, which is DOS's name for your keyboard and screen. The keyboard is the standard input device, and the display is the standard output and error device. In short, you type commands on the keyboard, and the commands and any error messages appear onscreen.

DOS enables you to choose the devices that you use to input and output information; this process is called redirection. (Error messages are always sent to the screen.)
