`GIT`基本操作

GIT是一个分布式版本控制软件，官网地址https://git-scm.com/

版本控制操作步骤：1，进入要管理的文件夹；2，初始化；3，管理；4，生成版本；下面是本次操作的流程演示过程

#第一步：进入要管理的文件夹
dream21th@dream21th MINGW64 /d/home
$ cd git-study/#第二步： 执行git初始化
dream21th@dream21th MINGW64 /d/home/git-study
$ git init
Initialized empty Git repository in D:/home/git-study/.git/#第三步： 查询需要管理的文件状态，abc.txt，index.html两个文件都未被管理
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git status
On branch masterNo commits yetUntracked files:(use "git add <file>..." to include in what will be committed)abc.txtindex.htmlnothing added to commit but untracked files present (use "git add" to track)#第四步： 通过add添加要管理的文件
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git add index.html
warning: in the working copy of 'index.html', LF will be replaced by CRLF the next time Git touches it#第五步： 查询需要管理的文件状态，发现只有abc.txt没有被管理，而index.html被git管理了
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git status
On branch masterNo commits yetChanges to be committed:(use "git rm --cached <file>..." to unstage)new file:   index.htmlUntracked files:(use "git add <file>..." to include in what will be committed)abc.txt
#第六步： 通过git add .让所有没有被管理的文件被管理起来
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git add .dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git status
On branch masterNo commits yetChanges to be committed:(use "git rm --cached <file>..." to unstage)new file:   abc.txtnew file:   index.html
#第七步：通过git commit添加版本控制
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git commit -m "v1"
[master (root-commit) 986868c] v12 files changed, 2 insertions(+)create mode 100644 abc.txtcreate mode 100644 index.htmldream21th@dream21th MINGW64 /d/home/git-study (master)
$ git status
On branch master
nothing to commit, working tree clean# 第八步：修改index.html文件
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ vim index.html# 第九步： 修改index.html
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ vim index.html# 第十步： 重新添加文件管理控制
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git status
On branch master

文件在管控台的三种颜色：红色（新增或者修改的文件），绿色（git已经管理的版本）。

`GIT`配置个人信息配置：

dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git config --global user.name "dream21th"dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git config --global user.email "dream21th@126.com"

`GIT`查看个人信息配置：

dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git config --global user.namedream21th@dream21th MINGW64 /d/home/git-study (master)
$ git config --global user.email

`GIT`的三大区域

GIT的三大区域是工作区，暂存区，版本库，他们之间的关系如下：

在这里插入图片描述

`GIT`回滚：`git reset`

# 第一步：查看提交的版本号，确认要回退的版本号
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git log

$ git reset --hard 1c7b174b6574698d880bc18efe38a7457cb2bd77
HEAD is now at 1c7b174 v2# 第三步： 回退后查看当前版本

$ git log

`GIT`恢复日志：`git reflog`

通过上面的例子版本已经回退到v2版本，假如这个时候，又想退回到原来的v3版本，可以通过下面的指令操作

# 第一步： 通过git reflog查询到v3的版本号
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git reflog
1c7b174 (HEAD -> master) HEAD@{1}: reset: moving to 1c7b174b6574698d880bc18efe38a7457cb2bd77
df3b201 HEAD@{2}: commit: v3
1c7b174 (HEAD -> master) HEAD@{3}: commit: v2
986868c HEAD@{4}: commit (initial): v1# 第二步： 通过git reset --hard加上版本号回退
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git reset --hard df3b201
HEAD is now at df3b201 v3# 第三步： 查看版本日志信息
dream21th@dream21th MINGW64 /d/home/git-study (master)
$ git log

除了上面采用git branch的方式创建分支，还可以采用git checkout -b 分支名创建一个分支并切换到新建的分支。

`GIT`合并分支

# 第一步： 切换到要合并的分支
