Are there any good git tutorials available somewhere, except for the official tutorial?
I like the mercurial book, but haven't found anything similar for git. I would like to start using git in some projects, and would therefore be able to point my colleagues to some good reading material. In this particular case, they are still mostly used to RCS and CVS.
Related question with a comment linking to a git tutorial and a guide to switching from svn.

Here's a great post with a ton of resources:
Git and Ruby: Git tutorials, articles and links for Rubyists
Even if you're not a Rubyist, there's lots of good stuff in there.
I highly, highly, highly recommend the Git Internals PDF and podcasts from PeepCode. It costs $9 but it does an excellent job of describing how Git works from a fundamental level. Once you understand that, a lot of all the other pieces will make a lot more sense. Whether your moving to Git from SVN, some other VCS, or starting from scratch it's really useful to "get" how Git works under the hood.
Also, Pragmatic Version Control with Git will be out in December of this year and, judging from their past books, it should be very good. The beta book is already available at the Pragmatic Programmers website.
There is the Git Community Book by Scott Chacon. It is nowhere near as complete as the Mercurial book though.
OGRE Git Tutorial is an excellent presentation about Git by Bart Trojanowski for the Ottawa Group of Ruby Enthusiasts. Flash as well as OggVorbis video is available along with pdf of slide. It starts from basics, into the innards of Git and then to common work flow and tasks of Git. If you have about 2 hours to spare and want to know all about Git, this is the place. One warning though, it's pretty dense at times and you may want to watch it couple of times over to fully grasp the concepts.
I used slide decks to get up to speed with Git and to stay sharp. Feel free to check them out. http://www.adamlowe.me/2009/09/git-cards-how-i-learning-continued.html They should cover most of the core commands you need to be functional with git.

I just wrote this tutorial. It's quite reader friendly, Let me know what you think. http://mathnathan.com/2010/07/09/git/
