git版本控制工具，可以多分支同时进行开发再合并，可以找到任何一个以前的提交的版本进行还原与多次尝试
记录每次提交的方式：git通过快照的方式来，svn是增量的方式
Linus Torvalds（简称“李纳斯”，linux之父)创办，所以完全兼容linux,命令相同
默认用的vim编译器
Head指针指向到当前版本

$ git
usage: git [--version] [--help] [-C <path>] [-c <name>=<value>]
           [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
           [-p | --paginate | -P | --no-pager] [--no-replace-objects] [--bare]
           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
           <command> [<args>]

These are common Git commands used in various situations:

start a working area (see also: git help tutorial)
   clone      Clone a repository into a new directory
   init       Create an empty Git repository or reinitialize an existing one

work on the current change (see also: git help everyday)
   add        Add file contents to the index
   mv         Move or rename a file, a directory, or a symlink
   reset      Reset current HEAD to the specified state
   rm         Remove files from the working tree and from the index

examine the history and state (see also: git help revisions)
   bisect     Use binary search to find the commit that introduced a bug
   grep       Print lines matching a pattern
   log        Show commit logs
   show       Show various types of objects
   status     Show the working tree status

grow, mark and tweak your common history
   branch     List, create, or delete branches
   checkout    Switch branches or restore working tree files
   commit     Record changes to the repository
   diff       Show changes between commits, commit and working tree, etc
   merge      Join two or more development histories together
   rebase     Reapply commits on top of another base tip
   tag        Create, list, delete or verify a tag object signed with GPG

collaborate (see also: git help workflows)
   fetch      Download objects and refs from another repository
   pull       Fetch from and integrate with another repository or a local branch
   push       Update remote refs along with associated objects

'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.

前进后退版本：git reset
最常用的是根据索引，根据hash的前几位简写也能跳
head^^^=head~3

create a new repository on the command line
echo “# test2” >> README.md
git init
git add README.md
git commit -m “first commit”
git remote add origin https://github.com/hongzhongzhang/test2.git
git push -u origin master (-m “直接写提交信息”)

push an existing repository from the command line
git remote add origin https://github.com/hongzhongzhang/test2.git
git push -u origin master

git status
git config user.email "zzh@example.com"
git config user.name “zzh”
在你的当前库里的.git目录下的config文件中会写入用户

[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
[user]
	email = zzh@example.com
	name = zzh

git config --global user.email "ZZH@global.com"
git config --global user.name “ZZH_Global”
在你的“~”家目录下存储全局用户在这里插入图片描述
这个文件长这样：

[user]
	email = ZZH@global.com
	name = ZZH_Global

git reflog
git log --oneline

git push https://github.com/hongzhongzhang/test.git master
git pull https://github.com/hongzhongzhang/test.git master

win10这个会记录你的登录信息，push等操作就可以不用输入信息，如果想要换必须把这里删除！！

git checkout 切换分支
git branch 查看分支

github上fork了别人的项目后，再同步更新别人的提交

用github网站和用git命令两种方式

github网站上操作

打开自己的仓库，进入code下面。
点击new pull request创建。
选择base fork
选择head fork
点击Create pull request，并填写创建信息。
点击Merge pull request 合并从源fork来的代码。
完成。

用git命令操作
先到本地仓库中打开bash编辑器

主要步骤如下：

git remote -v   //用git remote查看远程主机状态
git remote add upstream git@github.com:xxx/xxx.git  //添加起别名
git fetch upstream //先拉到本地库
git merge upstream/master //合并到本地库
git push //上传到远程库
