Details:
I would expect this to use -n1 to separate the whitespace-delimited parameters
"a" and "b" and "c" to print 3 separate lines:
root@rmoore:~# echo "a b c" | xargs -n1 -i{} echo foo {}
foo a b c
If I manually specify a space as the delimiter, it works as expected (and
gives an extra CR with the last line, since it's now "c\n"):
root@rmoore:~# echo "a b c" | xargs -d\ -n1 -i{} echo foo {}
foo a
foo b
foo c
If I run without -I{} as a substitution, it works as expected (and prints {}
explicitly):
root@rmoore:~# echo "a b c" | xargs -n1 echo foo {}
foo {} a
foo {} b
foo {} c
