How to push multiple branches from multiple commits?

Question

I never used git before GitHub released the Windows app, so I've never used it in command line.

So here's my situation:
I did some commits on master, then switched branch and did some commits there too. All without pushing to GitHub. When I then clicked sync in the the windows app (which I assume does git push), to my surprise, all my commits were pushed to my new branch - even the commits I made while I was in master.

Since this is the behavior of the windows app, I guess I have to use the command line.
What is the correct git push command to push the commits to the correct branches on the remote?

Answer 1

To push all branches (refs under refs/heads), use the following command (where origin is your remote):

git push origin --all 

---

You can also set push.default to matching in your config to push all branches having the same name on both ends by default. For example:

git config --global push.default matching 

Since Git 2.0 the default is simple which is the the safest option.

Answer 2

If you want to push several specific branches (for example branch1 and branch2) you can use:

git push origin branch1 branch2  

In Git >= 2.4 this operation can be done atomically (i.e. if it fails to push any of the branches specified nothing will be pushed):

git push --atomic origin branch1 branch2
