git發(fā)明了一個叫做暫存區(qū)的概念，但是為什么要發(fā)明這個概念呢？
沒有暫存區(qū)可以不？為什么一定要有暫存區(qū)?
git 一些基本概念
http://www.atatech.org/articles/11236
http://www.worldhello.net/2010/11/30/2166.html
git checkout feature/20160705_dev_slot_735955
本地丟棄
git reset --hard HEAD
1.git 沒有trunk，萬物皆branch，
2.git 比svn多了work區(qū)的概念，比如對于branch有遠程分支和本地分支，一定要分清楚。
處理沖突
你本地有改動，先提交掉，或者git stash; git pull; git stash pop
有沖突會報告both motified,處理掉之后通過git add 標記
最佳實踐
- glog -33
- git config --global branch.autosetuprebase always 參考：http://www.tuicool.com/articles/NzeQZz3
- gsta && gl && gstp
常用命令
合并遠程分支到本地
git merge --no-ff origin/zheliang-temp
git merge --no-ff origin/20160727_fun_to_tlive
feature/20160615_newant_707832
查看日志
git log --graph --left-right --cherry-pick --oneline
切換分支
git checkout -b remotes/origin/feature/20160615_newant_707832
git checkout命令加上-b參數(shù)表示創(chuàng)建并切換，這個命令實際上包含兩部分：1.創(chuàng)建本地分支 2.把本地HEAD文件指向遠程分支remotes/origin/feature/20160615_newant_707832.
等同于下面兩個命令：
git checkout dev
git br
- master
remotes/origin/feature/20160615_newant_707832
刪除本地分支：
git br -d remotes/origin/feature/20160615_newant_707832
Deleted branch remotes/origin/feature/20160615_newant_707832 (was dc1f1ef).
Git鼓勵大量使用分支：
查看分支：git branch
創(chuàng)建分支：git branch <name>
切換分支：git checkout <name>
創(chuàng)建+切換分支：git checkout -b <name>
合并某分支到當前分支：git merge <name>
刪除分支：git branch -d <name>
創(chuàng)建本地分支
git checkout -b 20160615_newant_707832
Switched to a new branch '20160615_newant_707832'指向遠程分支
git branch --set-upstream-to=remotes/origin/feature/20160615_newant_707832 20160615_newant_707832

- git push matching VS simple
建議使用：
git config --global push.default simple
matching是推送所有分支，simple是推送當前分支,次問題參考http://stackoverflow.com/questions/21839651/git-what-is-the-difference-between-push-default-matching-and-simple

git 回滾到上一個版本
命令：git reset --hard HEAD^
參考：http://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000/0013744142037508cf42e51debf49668810645e02887691000
回滾之后想恢復git reflog
git rebase 沖突
解決沖突之后 git rebase --continue ，不要git ci
