First I have to say that I'm absolutely new to linux .

Today I watched a movie-tutorial at milw0rm and the guy acting in this tut was using variables (like mac-address of AP, his own device, ESSID and so on) in other console-windows.

I know the command ("export AP=11:12:12") and in the other windows "$AP" for example, but this works for me only in the console where the variables were defined, not in the next console.

Is there anything I'm doing wrong with this ?
