关于github不清楚的可以百度，
在这里，可以创建一个新的仓库
点击Create repository后会出现下面这些信息，其中第一块是仓库的url链接
第二块是你在本地目录中创建一个READEME.md文件，然后进行初始化，在add和commit提交到分支，然后再关联仓库，最后通过push 推送本地代码到github。
第三块其实就是已创建了本地仓库的前提下，执行第二块后面两行命令，推送代码到github
$ git remote add origin git@github.com:LaoNiNi/Test.git fatal: remote origin already exists. laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git push -u origin master Counting objects: 2, done. Delta compression using up to 6 threads. Compressing objects: 100% (2/2), done. Writing objects: 100% (2/2), 235 bytes | 0 bytes/s, done. Total 2 (delta 0), reused 0 (delta 0) To github.com:LaoNiNi/Test.git 87faef8..43b2fe4 master -> master Branch master set up to track remote branch master from origin. laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $
现在我们可以通过url来把代码clone到本地
通过 git branch -r 可以查看本地和远程相关联的git分支有哪些。通过push时指定提交分支，可以让分支和远程分支关联。
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch -r origin/master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch * master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch dev laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch dev * master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ gir branch -r bash: gir: command not found laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch -r origin/master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch dev fatal: A branch named ‘dev‘ already exists. laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git push -u origin dev Total 0 (delta 0), reused 0 (delta 0) To github.com:LaoNiNi/Test.git * [new branch] dev -> dev Branch dev set up to track remote branch dev from origin. laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git branch -r origin/dev origin/master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $
当别的同事create和push新的分支到github时，我可以通过git branch -a 查看本地分支和远程分支有哪些，我们clone代码时只会把默认分支（master）clone到本地，并不包括别的分支，所以需要通过 git checkout -b bug /origin/bug 命令创建新分支，并且切换到新分支，而且关联远程的bug分支。
通过git remote -v 可以查看当前关联哪个远程git，通过git remote remove origin可以删除当前关联项
laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git remote -v origin git@github.com:LaoNiNi/Test.git (fetch) origin git@github.com:LaoNiNi/Test.git (push) laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git remote remove origin laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test (master) $ git remote -v
使用git pull origin 分支名称 可以更新远程分支，并且合并我当前分支，如果有冲突，会在本地有冲突的文件里出现提示。

但是git pull会自动帮我们合并分支，帮我们隐藏了很多细节，这样不能很好的掌控代码变化细节，

You are in ‘detached HEAD‘ state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new-branch-name> HEAD is now at 43b2fe4... second commit laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test2 ((43b2fe4...)) $ cat README2.md # Test laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test2 ((43b2fe4...)) $ git branch -a * (HEAD detached at origin/master) master remotes/origin/master laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test2 ((43b2fe4...)) $ git checkout master Previous HEAD position was 43b2fe4... second commit Switched to branch ‘master‘ laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/new_test2 (master) $ cat README2.md # Test This is a new file. laoni@DESKTOP-TPPLHIB MINGW64 /c/laon
所以我们合并分支时，可以用merge 加上 --no-ff参数这样有问题可以撤销：
