Git

1、本地操作
2、版本管理
3、远端仓库
4、分支管理
5、缓存stash
6、遗留rebase
7、标签管理
8、解决冲突
9、参考教程
10、示例代码

在这里插入图片描述

1、本地操作

Linux安装git：yum install git
查看git版本 git version
查看git设置 git config --list
设置git属性 git config --global
初始化git仓库：git init
初始化git用户邮箱：git config --global user.email “rice_van@email.com”
初始化git用户姓名：git config --global user.name “rice_van”
添加到仓库：git add filename.txt
提交到仓库：git commit -m “change messages”
查看仓库状态：git status
查看工作区修改区别：git diff
查看工作区文件区别：git diff HEAD – filename.txt
查看版本记录：git log
查看简洁记录：git log --pretty=oneline
查看命令记录：git reflog

2、版本管理

版本库提交流程：

第一步是用git add把文件添加进去，实际上就是把文件修改添加到暂存区；
第二步是用git commit提交更改，实际上就是把暂存区的所有内容提交到当前分支。

每次修改，如果不用git add到暂存区，那就不会加入到commit中
第一次修改 -> git add -> 第二次修改 -> git add -> git commit

HEAD表示当前版本
HEAD^表示上一版本，上上版本HEAD^^
前100次版本HEAD~100

回退最新提交：git reset --hard HEAD^ （即回到此版本的前一版本）
回到指定版本：git reset --hard commit_id
撤销暂存区修改，修改内容放回到工作区：git rest HEAD filename.txt
撤销工作区修改：git checkout -- filename.txt
回退本地误删文件：git checkout --filename.txt
删除仓库文件：
git rm filename.txt
git commit -m “remove filename.txt”

3、远端仓库

生成ssh秘钥：ssh-keygen -t rsa -C “xxxxxx@email.com”
克隆远端仓库到本地：git clone git@github.com:xxxxx/learngit.git
本地关联远程仓库：git remote add origin git@gitee.com:xxxxx/learngit.git
查看远端仓库：git remote
查看远程仓库信息：git remote -v
删除远端关联关系：git remote rm origin
本地修改推送远程仓库：git push origin master
本地修改推送远程仓库：git push -u origin master
推送到远端指定分支：git push origin originbranchname
抓取远程分支到本地：git checkout -b branchname origin/branchname
设置本地分支对应到远端指定分支：git branch --set-upstream-to=origin/branchname branchname
本地分支与远端分支名不同时：git push origin HEAD:branchname (远端名)

尽量保持本地分支名与远端分支名一致

4、分支管理

查看所有分支：git branch
创建分支：git branch branchname
删除分支：git branch -d branchname
强行删除为合并分支：git branch -D branchname
切换分支：git swtich branchname
创建并切换分支：git swtich -c branchname
合并到指定分支到当前分支：git merge branchname
禁用Fast Forward方式合并：git merge --no-ff -m “messages” branchname （删除分支后可看合并历史）
查看分支合并图：git log --graph
查看分支合并图简易：git log --graph --pretty=oneline --abbrev-commit
复制commit到当前分支：git cherry-pick commitid

5、缓存stash

缓存修改：git stash
缓存并标记：git stash -m “issue-01-2023.03.20:57”
缓存列表：git stash list
应用缓存：git stash apply
删除缓存：git stash drop
应用并删除：git stash pop
应用某一缓存：git stash apply stash@{4}

6、遗留rebase

7、标签管理

标签作用：标记commit，快速查看重要提交节点
添加标签默认添加到当前分支的最新commit：git tag v1.0
添加标签到指定commit：git tag v2.0 commitid
添加标签与说明信息：git tag -a v3.0 -m “version 3.0 released”
查看所有标签：git tag
查看详细标签：git show v2.0
删除标签：git tag -d v3.0
推送标签到远程：git push origin v1.0
推送所有标签：git push origin --tags
删除远端标签：
git tag -d v1.0
git push origin :refs/tags/v1.0

8、解决冲突

更新本地代码：git pull
查看状态：git status
手动修改，删除冲突内容
重新提交：git add 、 git commit
