FRIN? instead of FROM in the Terminal on MacOSX

I just signed up with Docker today and was running through the Getting Started guide. While on the page for “Build your own Image”, at step 3 I’ve come to a bizarre issue. The instruction is to use the command, “cat Dockerfile” in the Terminal. The response should be, “FROM docker/whalesay:latest”. Instead, I get “FRIN docker/whalesay:last”. A couple of commands later, you are to enter, “docker build -t docker-whale .” (with the period). The command fails with the error, “Unknown instruction: FRIN”.
Could there be a typo error in the tools I downloaded from Docker’s website?

It was my error & I found & fixed it.
