POSIX shell code works equally well, "[[ $? -ne 0 ]]" is not in the
slightest different from "[ $? -ne 0 ]" and the latter will work in
any shell - so use the latter, not the former.
On the other hand, there's no problem with using bash features when
you're writing a bash script and don't have to be concerned about
portability.
