I'm just doing this for fun and to learn about Go and Unix at the same time.

I am a beginner, and a lot of my code is inefficient and/or incomplete, but by putting it on the Internet I can get criticism and find out where I went wrong.

For instance, some of you have told me that the way I've been reading files is very inefficient, so now I'll try and do it the correct way.

That is a great reason to do this and the best way to learn.

That is the best reason. I am glad HN has people like you who are not afraid to put yourself out there and reminds us all that this is what being a hacker is: doing stuff for fun and learning.

except to you know, learn stuff

That's lame. I logged special just to downvote you.
