-<P><CODE>cat</CODE> still has a purpose though. This shell script is relatively slow for short files and very slow for very large files (though dd itself should probably be used to copy large files from one medium to another anyway). This is provided for educational purposes (though I personally use this shell script in my system PATH; the C implementation provided compiles to a much larger binary using gcc 11.1.0, so this saves a couple kilobytes).</P>
