Feature分支

软件开发中，总有无穷无尽的新的功能要不断添加进来。
添加一个新功能时，你肯定不希望因为一些实验性质的代码，把主分支搞乱了，所以，每添加一个新功能，最好新建一个feature分支，在上面开发，完成后，合并，最后，删除该feature分支。
1. 创建feature分支

$ git checkout -b feature
Switched to a new branch 'feature'

2. 添加feature.txt并提交代码

$ git status
On branch feature
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        feature.txt
nothing added to commit but untracked files present (use "git add" to track)
$ git add feature.txt
$ git commit -m "add feature"
[feature 6d99405] add feature
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 feature.txt

3. 删除分支

$ git checkout dev
Switched to branch 'dev'
$ git branch -d feature
error: The branch 'feature' is not fully merged.
If you are sure you want to delete it, run 'git branch -D feature'.

4. 强行删除

$ git branch -D feature
Deleted branch feature (was 6d99405).
