You can't set the environment for your parent process.  When you run these
scripts, they run in a subshell, and change the environment in that
subshell, when then closes, dumping the environment changes.

If you . in the script rather than running it straight out, it'll affect
your current shell.  Like this:
. ./script.sh
rather than
./script.sh

Cheers
