How to read git log graph
In the git community book, it says
Another interesting thing you can do is visualize the commit graph with the ‘–graph’ option, like so:
git get new file from repository Pushing git repository to Xcode Git push default to github git log --follow, show all commits including merges How to configure 'git diff' to use emacs diff Import a Python library from Github
$ git log --pretty=format:'%h : %s' --graph * 2d3acf9 : ignore errors from SIGCHLD on trap * 5e3ee11 : Merge branch 'master' of git://github.com/dustin/grit |\ | * 420eac9 : Added a method for getting the current branch. * | 30e367c : timeout code and tests * | 5a09431 : add timeout protection to grit * | e1193f8 : support for heads with slashes in them |/ * d6016bc : require time for xmlschema
It will give a pretty nice ASCII representation of the commit history lines.
How should I read this graph? How does
420eac9 differ from the rest?

d6016bcwas the branching point
5e3ee11is the merging commit
2d3acf9is the first commit after merging
420eac9 is on a different branch than the 3 commits “below” it. The branches diverged after
d6016bc and they were merged in
