how to push branch work to github and list unpushed git commit

Often time when we work on issue, we branch from master branch and started our development on the branch. However, if the branch work never published, your co developer cannot read the changes. In this article, we are going to learn how
to publish the branch work to github.

You should have familiar basic branch work in git. Example.

git branch my-branch-work
git checkout my-branch-work
// do develope work here until you are ready to merge to the master branch.
git checkout master
git merge my-branch-work

If your local branch has set to my-branch-work, if you are trying to pull down from github, you will get similar message below.

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> my-branch-work

That is when you should start to push your branch work to github.

jason@localhost:~$ git push -u origin my-branch-work
Username for 'https://github.com': xxxxxx
Password for 'https://xxxxxx@github.com':
Total 0 (delta 0), reused 0 (delta 0)
To https://github.com/organization/myproject.git
 * [new branch]      my-branch-work -> my-branch-work
Branch my-branch-work set up to track remote branch my-branch-work from origin.

Then make sure your local branch is also pointed to the correct branch

$ git branch
* my-branch-work
  master

The next time you do git pull, you will not receive the error. If you want to push your branch changes to github, you should use this command.

$ git push origin my-branch-work
Username for 'https://github.com': xxxxxx
Password for 'https://xxxxxx@github.com':

Often times, when you commit locally and you go on develop. Then probably pause for some period of time due to other priority works, and when you come back and do git status, you started to notice, hey, there is some local commit which you did not push but you forgotten what is actually in the commit. So is there a way to view it?

$ git status
On branch master
Your branch is ahead of 'origin/master' by 2 commits.
(use "git push" to publish your local commits)

Yes, there is, you can use command like git log origin/master..HEAD

Some additional command which is helpful including viewing the different using command git diff origin/master..HEAD
