When you run a script from bash it will be run in a new bash process and
  so all environment variables will be set in that new shell. To avoid
it and make your script run in current shell, use "source" builtin
command (or equivalent "."), e.g.

source test.sh

or

. test.sh

More detail in man bash (look for "SHELL BUILTIN COMMANDS" -> "source").
