Using the nul device, you can also copy files into nowhere: c:\> copy somefile.txt nul (then type this to emulate your DOS prompt) C:\> (first type this to initiate the process) c:\> copy con nul The user will be able to type commands, press enter, and scratch their heads while nothing happens and everything they type is sent directly to the nul hole: The following method will create a situation in which a DOS prompt exists, but fails to execute anything.

To quickly append lines of text to any file, use the output redirection command as follows: c:\> echo sometext > somefile.txt (to stop recording keystrokes) press or Add single lines of text to a file (to create a new line within the file) press (to create the text file and begin recording keystrokes) c:\> copy con files\docs\note.txt Here, we command DOS to record all keystrokes into a file called note.txt, which we will create in the c:\files\docs\ directory: While working in DOS, it is possible to create text documents easily, on the fly, and without any external text editor. (using the type command) c:\> type files\docs\atari.exe con Create text files in DOS (using the copy command) c:\> copy files\docs\atari.exe con Here we are displaying the contents of the file atari.exe, which is located within the c:\files\docs\ directory: Both of these methods employ the con (i.e., console, which consists of the keyboard and monitor) device.
