The current path, as well as all environment variables are only 
inherited by cild processes. You can never affect the parent process.

For a shell script to affect your own environment, it must not be run as 
a process of it's own, but instead must be run by your instance of the 
shell.

In sh (and affiliates), this is done by running the shellscrip as:

. <script>

. is a command in sh, which does just that.

In csh you instead type "source <script>"
