     If you do that in FreeBSD, you are not using bash; on FreeBSD, sh
     is the same as ash in Linux, and it doesn't have arrays.

     Try:

bash file.sh

     Or if bash is your shell, just:

file.sh

     Or you can put a shebang as the first line of your file (check the
     location of bash on your box):

#! /usr/local/bin/bash
