You do have to modify those files for it to be permanent.  If you just do that
in a terminal window, it only applies to that session and would be lost when
you exit the terminal or restart the system.

I had seen 'export' used before but I guess I didn't know exactly what it did. 
I did a quick search online and found this page:

It sounds like you could set an environment variable wihout export, but export
makes it apply to child processes (so if you start another instance of the
shell within the shell, the variable would apply there too).  I imagine the
export is probably important for running shell scripts, since a shell script
runs in another instance of the shell.
