$ git clone https://git.oschina.net/huanuo/do.git

remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
branch.master.remote=origin
branch.master.merge=refs/heads/master基本操作
- git add <文件名> 将工作目录的文件添加到缓存区域。
- git add * 添加所有文件到staging区域。
- git commit 打开一个编辑器编辑说明，然后将staging区域的文件提交到仓库中。
- git commit -m “说明” 将staging区域的文件提交到仓库中，附带简单说明。
- git commit -a 将工作区域的文件直接提交，跳过stage操作
- git status 查看当前的文件状态。
举例
// 创建新的文件 newfile.txt 然后查看当前的额文件状态
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Untracked files:
(use "git add ..." to include in what will be committed)
newfile.txt
$ git add newfile.txt // 将newfile.txt 添加到缓存区域
$ git commit -m "addnewfile" // 将缓存区域的文件 提交到仓库
[master 1210b9b] addnewfile
1 file changed, 1 insertion(+)
create mode 100644 newfile.txt 这样就完成了一个提交
查看文件的提交历史
git log 查看历史记录
git log -p 显示详细更改信息，
git log --pretty=oneline 显示简略信息
git log --pretty=oneline --graph 显示项目分支合并图。
举例

$ git log

e55ebbd9d4ea4b88134c66367dd0b52131f9b2d2 Initial commit 切换历史纪录
git checkout
举例
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do ((ba46162...))
$ git checkout e55e
Previous HEAD position was ba46162... add new file
HEAD is now at e55ebbd... Initial commit分支管理
git 中的分支就是一个可移动指针，指向了某个历史记录。 默认的分支名是 master 。每次提交后， master 都会指向你刚才的提交记录。
git branch
git checkout -b
举例
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (master)
$ git branch newbranch
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (master)
$ git checkout newbranch
Switched to branch 'newbranch'
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (newbranch)
$ git checkout -b anobranch
Switched to a new branch 'anobranch'
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$在新的分支上添加文件
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ touch hellobranch.txt
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ ls
hellobranch.txt newfile.txt README.md
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ vim hellobranch.txt
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ git add hellobranch.txt
warning: LF will be replaced by CRLF in hellobranch.txt.
The file will have its original line endings in your working directory.
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ git commit -m "add hello branch"
[anobranch 14641f3] add hello branch
1 file changed, 1 insertion(+)
create mode 100644 hellobranch.txt合并分支
git merge hotfix
举例
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (anobranch)
$ git checkout master // 切换到主分支
Switched to branch 'master'
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (master)
$ git merge anobranch // 合并分支
Updating ba46162..14641f3
Fast-forward
hellobranch.txt | 1 +
1 file changed, 1 insertion(+)
create mode 100644 hellobranch.txt删除分支
git branch -d branchname
举例
fan@DESKTOP-1OGO4V1 MINGW64 ~/Desktop/gti/do (master)
$ git branch -d anobranch
Deleted branch anobranch (was 14641f3).远程仓库操作
