Debian shadowfile and hashcat CUDA

[mastercracker]

Thanks, but I have a problem. I make a seperate shadowfile and fill in only this Hashcode "On6ZrLf4xHOpM:11761"

cudaHashcat-plus64.exe --hash-type 1500 --attack-mode 3 U:\backtrack\shadow ?u?l

I get this the error
ERROR: No hashes loaded

Because you have to remove the :11761 part, it's not part of the hash. Look at my example, it's only the 13 characters part that is the hash.
