By default, Shells will only keep all variables to the Shell in which they run. This is good, since it assumes variables are not needed outside of a given script. In most cases, that is correct. But, if you have a script that you want to use to set Shell variables, it must be exported in some way. Alternative ways to export variables, is to call a script with "source" or just with a dot and a whitespace.
