Easy for you, hard for me - mask writing

[mastercracker]

I'm very sorry, maybe this question is so simple and obvious is the reason why there is nothing in FAQ or any of the tutorials. I realize most of you are too expert to waste your time on this, but it's very frustrating. I've been working on this password for days, finally got it to this point, and to me at least the results or where to find the results of my hashcat attack are not easy to see at all. I do appreciate your time, thanks.

In case it isn't clear, my question is: How do I know if it worked? and Where are the results?

Again, in the wiki...
You can use -o found.txt and your passwords (if found) will be in there. By default, it will also be in oclhashcat.pot. I guess the file is created only when 1 password is cracked so you might get your error with --show because there was no cracked passwords.
