Git 尝试

2,安装GIt

3,config :

git config --global user.name "mxb"
git config --global user.email "357670442@qq.com"

4,创建目录并且进行初始化

cd c:
mkdir GitRep
cd c:GitRep
git init

5,创建readme.txt 并提交

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git add readme.txt

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git status
On branch master

No commits yet

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)
        new file:   readme.txt


Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git commit -m "wrote a readme.txt"
[master (root-commit) 654c826] wrote a readme.txt
 1 file changed, 2 insertions(+)
 create mode 100644 readme.txt

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)

6,常用操作:

$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   readme.txt

no changes added to commit (use "git add" and/or "git commit -a")



$ git diff readme.txt
diff --git a/readme.txt b/readme.txt
index 3a94755..3c2ffbf 100644
--- a/readme.txt
+++ b/readme.txt
@@ -1,2 +1,3 @@
 Git is a version control system.
-Git is free software.

+Git is free software.

7,查看提交log 和版本回退

分别是,提交ID,提交的分支名称master,并且当前指针 HEAD 指向 master

提交作者,提交日期.

8,版本回退 git reset –hard HEAD HEAD^ HEAD~100 分别标识版本号. 或者

git reset –hard 版本号 .将版本库的信息--->工作区.

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git reset --hard 654c
HEAD is now at 654c826 wrote a readme.txt

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git add readme.txt

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git commit -m "third commit"
[master 4f76d7a] third commit
 1 file changed, 2 insertions(+), 1 deletion(-)

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git reflog
4f76d7a (HEAD -> master) HEAD@{0}: commit: third commit
654c826 HEAD@{1}: reset: moving to 654c
949a51f HEAD@{2}: commit: second commit
654c826 HEAD@{3}: commit (initial): wrote a readme.txt

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)

10,git理论

Git 保存当前库中文件状态 --- add -----> stage ---- commit ---> 版本库.

uncheck file -------------取消暂存区.

restore file -------------将暂存区的文件恢复到工作区

reset –hard 版本号 ------------将版本区的文件恢复到工作区.

GIt 查看命令 git status ---查看状态;git diff ---查看区别.

Git log 查看当前保存的版本号

Git reflog 查看版本操作.

11,删除文件相关操作

$ git status
On branch master
Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	deleted:    test.txt

no changes added to commit (use "git add" and/or "git commit -a")

12, 创建SSH密钥

12.1 利用命令创建SSH,并且在Administrator文件夹下面找到SSH.PUB

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ ssh-keygen -t rsa -C "357670442@qq.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Created directory '/c/Users/Administrator/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:fBzUtP87VnN1GcGy8nDxNqgFUf6IXxhimla+nelWi1w 357670442@qq.com
The key's randomart image is:
+---[RSA 3072]----+
|          .++....|
|         . .o+ o |
|          .+oo* o|

+----[SHA256]-----+

12.2 在GITHUB里面登陆,并且在Setting –>SSH AND GPG KEYS 里面添加 SSH kEYS.

12.3 将本地仓库GitRep 关联到远程的GitRep

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git remote add origin git@github.com:357670442/GitRep.git

Administrator@Mxb20200114 MINGW64 /c/GitRep (master)
$ git push -u origin master// +u 不仅推送本地分支(版本分支)而且还进行了关联.
The authenticity of host 'github.com (13.250.177.223)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

要关联一个远程库，使用命令git remote add origin git@server-name:path/repo-name.git；

关联后，使用命令git push -u origin master第一次推送master分支的所有内容；

此后，每次本地提交后，只要有必要，就可以使用命令git push origin master推送最新修改；

13,从远程库克隆

cd c:
$ cd c:

Administrator@Mxb20200114 MINGW64 /c

14,分支管理

14.1 分支理论

一开始的时候，master分支是一条线，Git用master指向最新的提交，再用HEAD指向master，就能确定当前分支，以及当前分支的提交点：

增加分支后A

此后,每一次提交就变化了B

分支合并C

分支删除D

14.2 实战

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git checkout -b dev  //创建并新建分支.情况A
Switched to a new branch 'dev'

Administrator@Mxb20200114 MINGW64 /c/gitrep (dev)
$ git add readme.txt


Administrator@Mxb20200114 MINGW64 /c/gitrep (dev)
$ git commit -m " dev branch"//新的提交  ,情况B
[dev 340b649]  dev branch
 1 file changed, 2 insertions(+), 1 deletion(-)

Administrator@Mxb20200114 MINGW64 /c/gitrep (dev)
$ git checkout master  //切换到master分支,并且更改当前工作区内容.
Switched to branch 'master'
Your branch is up to date with 'origin/master'.

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git checkout dev  //更改到分支dev,变化B.
Switched to branch 'dev'

Administrator@Mxb20200114 MINGW64 /c/gitrep (dev)
$ git checkout master  //切换到master分支,HEAD 指向Master.
Switched to branch 'master'
Your branch is up to date with 'origin/master'.

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git merge dev   //将master--超前到dev,合并.master指向dev.
Updating 4f76d7a..340b649
Fast-forward
 readme.txt | 3 ++-
 1 file changed, 2 insertions(+), 1 deletion(-)

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git branch -d dev  删除dev分支.(也就是删除dev指针).
Deleted branch dev (was 340b649).

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git branch  //查看当前branch.
* master

Git鼓励大量使用分支：

查看分支：git branch

创建分支：git branch <name>

切换分支：git checkout <name>或者git switch <name>

创建+切换分支：git checkout -b <name>或者git switch -c <name>

合并某分支到当前分支：git merge <name>

删除分支：git branch -d <name>

14.3 Git 合并冲突分支的方法:

Administrator@Mxb20200114 MINGW64 ~
$ cd GitRep
bash: cd: GitRep: No such file or directory

Administrator@Mxb20200114 MINGW64 ~
$ cd c:gitrep

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git branch
  feature1
* master

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git branch -d feature1
Deleted branch feature1 (was 4ecc3a5).

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git status
On branch master
Your branch is ahead of 'origin/master' by 4 commits.
  (use "git push" to publish your local commits)

nothing to commit, working tree clean

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git push origin master

Git解决冲突的方法,在回到Master之后,进行Merge,然后其再上一个版本,这个时候,手动进行文件更改,然后

再次进行合并.用git log --graph命令可以看到分支合并图。按q退出.

14.4分支管理策略

使用 $ git merge --no-ff -m "merge with no-ff" dev

新建一个commit,然后进行合并.

删除未合并的分支:

git branch -D <name>强行删除

标签的使用方法

Administrator@Mxb20200114 MINGW64 /c/gitrep (master)
$ git tag v0.9 340b64

远程的操作:

远程仓库查看 git remote –v

远程慷慨添加 git remote add origin https://gitee.com/mao_qin_bin/GitRep.git

远程仓库删除 git remote rm origin
