Like everything else, it depends on your goals. If portability across
different OSs is a goal, and you can't be guaranteed that bash will be
available, it's best to stick with POSIX features. If you want to run
places where you can be guaranteed that bash exists, use whatever
`bashisms' you like and use `#! /bin/bash'.
