From the git homepage:
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.
Git is similar to CVS, SVN, etc. but the cheap local branching make it feasible to use a very powerful workflow where you can checkout, try something, backup, test something different, switch back to attempt 1 -- all without losing any of your work. You can also easily merge between these different branches and push-pull pieces of commits from others. It is ideal for the kind of highly distributed development we do at JLab.
Some general links to help users come up to speed with git.
- About git A quick read on what makes git different, and why you should care.
- Why You Should Switch from Subversion to Git: This article lays out the differences between git and svn/cvs. Comments for and against are interesting too.
- A successful Git branching model: A well written post how to take advantage of what makes git unique.
- Pro Git: An open-source, free, book on how to work with git (PDF, and eBook formats). Also available on Amazon if you want something on dead trees.
- git Homepage
- git's "Official" documentation
- This contains links to How To videos, as well as "Getting started" and "Git Basics" tutorials.
- Free GitHub Class: GitHub runs these web seminars every few weeks. Keep an eye out for a seminar that you might find interesting and sign up.
- Everyday GIT With 20 Commands Or So: Nice site that walks through some "typical" development tasks.
- Interactive cheatsheet for Git.
Tweaks:
- Add the current git branch and status to your bash prompt
- Save git-prompt.sh to '~/bin/git-prompt.sh' under your account
- Edit your ~/.bashrc file and add this line somewhere towards the end
[ -r ~/bin/git-prompt.sh ] && source ~/bin/git-prompt.sh
- Note: This calls 'git status' to generate prompt and can cause the shell to stall for a short period the first time you enter a repo if the git metadata isn't cached. I only find this delay noticable for really bit repositories like the linux kernel. Once the git info is cached, (ie. after the first longish delay) the prompt returns very quickly again.
NOTE: If you find a resource that you really appreciate. PLEASE ADD IT TO THE LIST!
