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.
An example would be
$ touch one two three
$ ls one two three | xargs -J [] mv [] [].suffix
I should now have one.suffix two.suffix three.suffix. At least,
that's what happens with GNU and the -i \{\}. (FreeBSD manpage
says to use -J [] without escapes though.)
Can anyone lend me a clue here please?
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.

I have a map of the United States. It's actual size.
I spent last summer folding it. People ask me where
I live, and I say, E6. -- Steven Wright

I've never tried to do it this way, but I suspect that you can only use
your delimiter once.
In any case, if what you are wanting to do is rename a bunch of files,
try something like:
# for file in one two three; do mv $file `echo $file | sed -e
's/$/.suffix/'`; done
That's the way I've always done it - works a treat (try doing THAT with
a GUI :-)
Hope it helps, unless you had your heart set on xargs

Two things. First, from `man xargs`:
Furthermore, only the first occurrence of the replstr will be
replaced. Second, maybe a different tool would be better. How
about:
$ for file in `ls one two three`; do move $file $file.suffix; done

I think what you want here is -I instead of -J. -I allows for multiple
replacements, whereas -J does not.
Also, I'd suggest using something other than [] as your placeholder, as
those characters have a special meaning in the shell. Using something
simple, like %, as the man page illustrates.
