Mastering Git: Attain expert level proficiency with Git for enhanced productivity and efficient collaboration

This is a great book about git, the command line tool, and service. It talks about generic git (as opposed to GitHub/Bitbucket specific features.) I really like that it does talk just about git, everything in the book should work on any operating system, and it is everything every developer needs to know to use git daily (and some fun things like prompts and alias' are also covered.)The only thing keeping this from 5 stars is printing more sample output in the book. It is hands on, but if you are reading w/o a computer in front of you, it can be hard to follow. My advice is to just read the book with an open terminal.
