I think it has to do with how you run the script.

If you do:

sh ./script.sh

Or

./script.sh

Then it invokes a new shell, runs the script, then returns you to the current one. So the cd is done in the new shell and your current one is untouched.

Try this instead:

. ./script.sh

Which will run script.sh in your current shell, and you'll keep the results after it finishes.
