  4. 4. So, what is git anyway? git is a distributed version control system, that is open source and made with speed in mind
  5. 5. Quick git History ■ Linus Torvalds was using a DVCS named BitKeeper, but then BitKeeper withdrew the free version of its product ■ This inspired Linus to create his own DVCS to keep up with the demands of thousands of people working on the Linux kernel [2]
  6. 6. Git and the competition And by competition I mean SVN and Mercurial
  7. 7. ● Online vs Offline ○ No need to get on the company VPN if you only have to local work. Since git is a full repository locally, you don’t need a network connection to use source control ● Speed ● Branching ● Ease of Use Git vs SVN
  8. 8. Git vs SVN Data Representation is different as well
  9. 9. SVN Git
  10. 10. Git vs Mercurial (Hg) ● Ease of Use ● Flexibility “Git is MacGyver, and Mercurial is James Bond” http://importantshock.wordpress.com/2008/08/07/git-vs-mercurial/ [4][3]

  20. 20. One of the quickest ways to get a GUI with git, is to just type in git gui into your console. It will pop up a basic GTK GUI to do most things with Git Git GUI
  21. 21. SourceTree SourceTree is a fantastic full featured GUI client for Git It surfaces all the major git commands as large buttons so that there is no effort to use Git on a day to day basis. It also gives great visuals on the history of a Git repository to help find that pesky commit you are looking for
  22. 22. Now its time for some tricks? git diff --name-status master..branch finds the differences between two named branches git log --pretty=oneline gives one line log history that looks great
  23. 23. Tricks continued git stash - will save all uncommited changes into the git local repository. you can git stash pop to get these changes back at any time. git checkout -b branchname hash lets you create and switch to a new branch with the HEAD placed at the commit referenced by the hash
