git config push default

steps

1. dive into your repo

2. do some editing and commit it

        $ git add .
        $ git commit -m "fix some bugs"
   

3. then push

        $ git push
   
        warning: push.default is unset; its implicit value has changed in
        Git 2.0 from 'matching' to 'simple'. To squelch this message
        and maintain the traditional behavior, use:
   
          git config --global push.default matching
   
        To squelch this message and adopt the new behavior now, use:
   
          git config --global push.default simple
   
        When push.default is set to 'matching', git will push local branches
        to the remote branches that already exist with the same name.
   
        Since Git 2.0, Git defaults to the more conservative 'simple'
        behavior, which only pushes the current branch to the corresponding
        remote branch that 'git pull' uses to update the current branch.
   
        See 'git help config' and search for 'push.default' for further information.
        (the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
        'current' instead of 'simple' if you sometimes use older versions of Git)

4. config your git

        $ git config --global push.default simple
        $ git config --global push.default
        simple
   

5. do some editing commit it and push

        $ git add .
        $ git commit -m "fix more"
        $ git push
        To https://github.com/gree2/gree2.github.com.git
           fcb3bbf..c40f11a  master -> master
