This is sort of like saying "I like to not rely on hiking boots when
shoes can do the job."

If "not actually splitting" means what it seems to mean, and you
literally want to run cksum, the answer is no.  The things on the
cksum command line have to be file names, so you'd have to create a
file for each line of the original input.

The other option would be to write the CRC algorithm as a shell function.
