My understanding is that it will create the splits to contain whole
files. So if you are compressing a folder full of little files then
zipsplit can work well. If you are trying to split a single large file,
like a video file, then zipsplit won't be able to break it up. It's also
limited to 2GB per split file. You have to specify the max number of
bytes per split file with the -n parameter. So if you wanted 10MB files
you would put -n 10485760. zipsplit also won't take data piped into it
so you have to create the zip file first then run zipsplit on that. The
unixy way using split and cat is just more robust but at least with
terminal on osx you have lots of ways to do things. Of course the real
unixy way would be to use tar -zcvf to create a compressed archive. Tar
stands for Tape Archive, which gives you an idea how far back that
command goes. In all cases doing "man command_name" will give you the
manual page for whatever command you want to know about. "man tar" will
give you all the options and examples for the tar command, and yes, you
can do "man man" to find out how to use the man command :)

Be aware that the technique of using split and cat, while certainly effective,
is not actually the same thing as producing what the current zip tools call
“Split” (or, before then, “Spanned”) archives. For the production of the
former from an already-created zip file, see zipsplit(1), which is part of
InfoZIP and is also already on your Mac (requires command-line foo). The
resulting files will include the necessary magic header, and end up as
file.zip, file.z00, file.z01, and so forth.
