Have you taken a look at the split csv files?

You're splitting in bytes, which means that unless your csv files are *very* reliably structured, you will likely break the file up into chunks that break full lines.

Say you have a file like this:

1,2,3,4,5

[download]

and a read statement like this:

read $fh, $chunk, 5;

[download]

You'll end up with split file one with:

1,2,3

[download]

and the second split file with:

,4,5

[download]

Which might not be what you wanted.
