Note that this is not a
Java question at all; this probably belongs in "General Computing."
Anyway, you have to put the shell commands you're showing us into a file that is executed when your shell starts. Precisely -which- file to use depends on which shell you're using, and also to a lesser extent on the details of how your system is set up. Your best bet is to put those lines into a file in your home directory named .bashrc (note that the name starts with a period, making it an "invisible" file.)
