I'm quite familiar with Dir.chdir("/xyz")

Unfortunately, this changes the directory of the process, but not actually the directory of the user. I'll make the following example to illustrate my need.

```
$~/: ruby my_script.rb
CHANGING TO PATH FOR USER NOT SCRIPT

$/Projects/Important/Path: pwd
$/Projects/Important/Path

```

See? I need the script to change the user's path. Performing system/backticks/Dir.chdir all adjust the process path, and end with the user sitting where they started, instead of the path I want them.

From what I've read `exec` was the way to go, since it takes over the existing process... but to no avail.
