Question

This is probably quite simple but I’m currently a git noob and haven’t quite got my head round the git branching model yet.

Suppose I currently have no branches other than master, but now I’ve made some changes since my last commit that I’ve decided I don’t want to keep (note: the changes are not committed yet). I don’t want to get rid of these changes just yet though – I’d like to put them in their own branch (called e.g. experimental_stuff) and then continue development from my previous commit. So I guess the steps are:

• make current master a branch (git branch experimental_stuff ?)
• go back to previous commit (git checkout <last_commit> ?)
• make this my new master branch so that future commits continue from here (git ??? ?)

Is this the right approach and what git command do I need for the last part (if any) ?

[Note: this is just a local git repository for my sole use, if that make any difference.]

Answer 1

you are almost done.

Assume you have made a commit on your development files. Then..

git branch experimental_stuff

git reset –hard HEAD^ (go back one previous commit of your master branch to continue your development)

Assume you have not made a commit on your development files. Then..
you need to save your current changes to a temporary directory

git stash

git checkout -b experimental_stuff (create and change branch to experiental_stuff)

git stash pop (populate the temporary directory into experimental branch)

git checkout master (return back to master, and no need to go back the previous commit this time as you don’t have that commit)
