Awesome script, makes stuff a lot faster.
I ran into some problems tho,
The first time I tied to crack my WPA PSK key I found the key in my own wordlist. (Just a wordlist containing 5 words where one of them is my password)
I later tried again with the very same wordlist and it just stated that the key was not in my wordlist. All and all I tried 3 or 4 times, where only 1 showed my key.
I doubt its your script but has anyone had problems like this with aircrack-ng or with this script?
