: dd if=your_file of=aaa count=2000 (BTW: 2000*512 byte)
: dd if=your_file of=bbb skip=2000 count=2000
: dd if=your_file of=ccc skip=4000 count=2000
: ....
or more simpler:
split -b 1000k file part.
this will give you part.aa part.ab part.ac ... of each 1000kbytes which you
may also cat together
cat part.a* >> file (or cat part.* if it goes to part.b* etc)
t
p.s.: this is the way the FreeBSD distribution is made
