I agree, dd is a nice program, however, there is a utility program made
just for this kind of problem. The program is "split" used to split
large files into smaller files. The syntax is:
split -n filename
where n is the number of lines per smaller file. If n is not specified,
the default is 1000 lines.
The resultant filenames will have the name appended with .aa .ab ....zz
