If you're using '-i' with GNU xargs, then you probably don't want
'-J' on the xargs in freebsd. -J is meant to solve a problem that
can not be handled via -I.

The man page for xargs says:
Furthermore, only the first occurrence of the
replstr will be replaced.
in the description of -J.
For your example, what you should use is -I, not -J.
