I think the parent was referring to using awk/sed to do the equivalent of:

    find ... | tr '\n' '\0' | xargs -0 ...

I.e., a blind replacement without the tool having any particular semantic understanding of what it's translating.

That still requires your xargs to have -0 support, though, and I'd be surprised to have that without the corresponding option on find. But I've done this before when feeding xargs from something other than find.
