Linux in a Nutshell, 6th Edition...
...has a new chapter about Git, courtesy of me.
Sorry for the late notice. I keep thinking of awesome stuff to write about, but not quite getting around to it because I'm too busy. Somehow it's the opposite of writer's block, but has the same net effect.
As computer books go, Linux in a Nutshell is surprisingly awesome. I've been using Linux pretty heavily since 1994, but I can still flip to a random page in this book and learn something new.
Unless I flip to the Git chapter, of course.
