在利用git做版本管理时，已经checkout了许多分支，如下所示。这时想push指定分支（story7_homepage2.0）到github，应该怎么做了。

MacBook-Pro ⮀ ~/jdstore ⮀ ⭠ story7_homepage2.0 ⮀ git branch
  EPIC-1
  EPIC-1-archive
  competion
  master
  story1
  story2
  story3
  story4
  story5
  story5_figaro
  story5_orderstatus
  story6header
* story7_homepage2.0

在命令窗口执行以下命令
git add .
git commit -m ""
git push origin sotry7_homepage2.0

MacBook-Pro ⮀ ~/jdstore ⮀ ⭠ story7_homepage2.0± ⮀ git add .
MacBook-Pro ⮀ ~/jdstore ⮀ ⭠ story7_homepage2.0± ⮀ git commit -m "upload gem 'fog' to 'fog-was';update carrierwave.rb"

 * [new branch]      story7_homepage2.0 -> story7_homepage2.0

然后再去刷新Github的repo，发现story7_homepage2.0已经被成功的push上去了。
