-n [lines] Display n consecutive lines.
rndl should read the size of the file, assess what is generally the size, in characters, of a line in the file, and guess how many lines there are. It then picks one of these lines uniformly and seeks to a good estimate of its location, and reads the most nearby line. If n is specified, it will read that and n-1 lines ahead of it.
