The reason you're having inconsistent behavior is because Linux has /bin/sh symbolically linked to /bin/bash while FreeBSD has a more traditional shell (we'll call it bourne shell "plus"). that is misleading because command substitutions have traditionally invoked subshells, and freebsd sh(1)/ash is an exception, not the norm in this case, ksh and bash deviates are clearly closer to standard bourne behaviourhelp
