Git create branch off previous commit
This effectively changes history, since it is no longer clear where the branching occurred. Note that the rebase command will perform a similar operation, but without creating a new “merge” commit-it simply takes the commits from one branch and attaches them to the end of the other. And if you’re unsure why something isn’t working with git, use git status to check the current status and for what steps to do next.

IMPORTANT If something goes wrong, don’t panic and try to close your command-line! Come back to this book and look up how to fix the problem you’ve encountered (e.g., how to exit vim). So if you want to end up with the “combined” version of your commits on a particular branch, you’ll need to switch to ( checkout) that branch before you run the merge. This command will merge other_branch into the current branch. You can view a list of current branches in the repo with the command
If you decided that the experiment didn’t work out, you can simply delete those set of changes without ever having messed with your “core” master branch.
#Git create branch off previous commit code
And once you decide you’re happy with the code added to both versions, you can merge them back together, so that the master branch now contains all the changes that were made on the experiment branch. You can even branch off further versions (e.g., a bugfix to fix a problem) if you wish. You can develop master and experiment simultaneously, making changes to each version of the code. But then you decide to make further changes to your main development line, adding more commits to master that ignore the changes stored in the experiment branch. You split off a new branch (called for example experiment), which saves some funky changes to your code. In this example, you have a primary branch (called the master branch), and decide you want to try an experiment.
