Here is a quick and dirty script I came up with to split an input file into mutiple 500k chunks. Just pass a filename as a parameter. You can put the chunks back by using: cat chunk-1 chunk-2 chunk-n > singlefile

#!/bin/bash
filesize=`stat -c %s $1`
processed=0
partcount=1

while (( $processed <= $filesize ))
do
dd if=$1 of=$1.part$partcount bs=1 skip=$processed count=500000
processed=`expr $processed + 500000`
partcount=`expr $partcount + 1`
done

split -b or split -l, depending on whether you want to split it by lines or bytes. See "man split"
