Its probably something easy, but I cannot figure this out. I cannot get john the ripper to work properly with BT4 prefinal. Ive tried numerous things from cracking a password, --show, --test, etc. No matter what i type in It just shows the "john --help screen" with all the different options.

Also if i boot to BT3, john works fine, but i would like it to work in bt4...

Here is what i type in: (all i get is the page with options)
john file.txt
john --show file.txt
john --test

Any help would be greatly appreciated! Thank you.
