github删除项目的文件夹(本地文件夹上传github)


一、git使用前准备

git本地仓库与github远程仓库连接时要有认证,是通过SSH的公钥进行认证的。创建SSH公钥并将添加到github中

在用户目录下查看.ssh文件夹

git及github的使用

如果没有这个文件夹或者文件,需要手动创建

在Program Files文件夹下找到Git/bin目录,双击sh.exe

git及github的使用

输入以下命令,一路回车会创建.ssh文件夹和其中的密钥

$ ssh-keygen -t rsa -C "xxxx@xx.xx"

用记事本打开id_rsa.pub文件,将其中的公钥复制。

打开https://github.com,打开设置页

本地仓库与远程仓库的连接有三种方式:

  1. 初始化本地仓库,然后将本地仓库推送到远程仓库;
  2. 将一个已有的本地仓库推送到远程仓库;
  3. clone一个远程仓库到本地。

三、git基本操作

初始化:git init

新建一个文件夹gitdemo并初始化

$ cd g:
 
Administrator@User-14 MINGW64 /g
$ mkdir gitdemo
 
Administrator@User-14 MINGW64 /g (master)
$ cd gitdemo
 
Administrator@User-14 MINGW64 /g/gitdemo
$ git init
Initialized empty Git repository in G:/gitdemo/.git/
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$

初始化会在当前文件夹下创建一个.git的文件夹,此文件夹存储着管理当前目录内容所需的仓库数据。

查看本地仓库状态: git status

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git status
On branch master    //当前在master分支
 
No commits yet      //没有过提交记录
 
nothing to commit (create/copy files and use "git add" to track) //暂存区没有要提交的文件

在当前文件夹下创建一个文件后再次查看仓库状态

git及github的使用
$ git status
On branch master
 
No commits yet   //没有过提交记录
 
Untracked files:           //存在一个没有被git跟踪的文件
  (use "git add <file>..." to include in what will be committed)
 
        test.txt
//没有需要提交的,但是存在没有被git跟踪的文件
nothing added to commit but untracked files present (use "git add" to track)

将文件添加到暂存区:git add 文件名/git add .

git add .代表的是添加所有的文件到暂存区

上面创建的test.txt文件,由于没有git操作因此是不会被git跟踪的,git向仓库中添加要先将工作区文件添加到暂存区后才能提交到仓库。

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git add test.txt   //将文件添加到暂存区
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git status
On branch master
 
No commits yet
 
Changes to be committed:    //暂存区中没有提交的文件
  (use "git rm --cached <file>..." to unstage)
 
        new file:   test.txt

当test.txt文件内容更改时,再次查看状态

$ git status
On branch master
 
No commits yet
 
Changes to be committed:  //暂存区中存在没有被提交的文件
  (use "git rm --cached <file>..." to unstage)
 
        new file:   test.txt
 
Changes not staged for commit:  //文件改变了但是没有添加到暂存区
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
 
        modified:   test.txt
 

提交暂存区文件到本地仓库:git commit -m “description”

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git commit -m "first"    //提交暂存区文件
[master (root-commit) dc1a2af] first
 1 file changed, 1 insertion(+)
 create mode 100644 test.txt
 
========text.txt文件改变了===========
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git status
On branch master
Changes not staged for commit:  //以下文件存在改动但是没有提交暂存区
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
 
        modified:   test.txt
 
no changes added to commit (use "git add" and/or "git commit -a")
 
=================添加改动的文件到暂存区后再提交========================
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git add .
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git commit -m "second"
g[master 3e6b279] second
 1 file changed, 1 insertion(+), 1 deletion(-)
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git status

四、分支操作

git默认分支为master,以此基础上创建不同的分支,由不可的开发人员进行修改,然后再进行合并到master分支。分支有利于版本控制和团队协作。

git及github的使用

查看分支列表:git branch

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git branch
* master              //分支名前带有*号表示当前所在的分支

分支的创建与切换

  1. 分支创建git branch XX
  2. 分支切换git checkout XX
  3. 分支创建并切换git checkout -b XX
  4. 切换上一个分支git checkout –
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git branch A   //1创建分支A
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git branch     //分支列表,当前分支还是在主分支上
  A
* master
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git checkout A    //2切换当前分支为A
Switched to branch 'A'
M       test.txt
 
Administrator@User-14 MINGW64 /g/gitdemo (A)
$ git branch    //分支列表显示当前分支为A
* A
  master
 
Administrator@User-14 MINGW64 /g/gitdemo (A)
$ git checkout master    //切换到主分支上
Switched to branch 'master'
M       test.txt
 
====================
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git checkout -b B   //创建分支B并切换到B
Switched to a new branch 'B'
M       test.txt
 
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git branch      //分支列表显示当前为B分支
  A
* B
  master
 
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git checkout -   //切换上一个分支master
Switched to branch 'master'
M       test.txt

番外:

  1. git checkout master^ 使HEAD指向当前的上一记录。
  2. git checkout master~1 等同上行。
  3. git checkout master~n 使HEAD指向当前的上n条记录处。

分支的删除:git branch -D fname

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git branch -D B
Deleted branch B (was 670ec48).
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git branch
* master

git branch -f bugFix master 强制bugFix分支指向master

分支的合并:git merge fname

//先要切换到合并后的分支
Administrator@User-14 MINGW64 /g/gitdemo (A)
$ git branch master
fatal: A branch named 'master' already exists.
 
Administrator@User-14 MINGW64 /g/gitdemo (A)
$ git merge A
Already up to date.

五、更改提交的操作

回溯历史版本:git reset

//查看操作日志
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git reflog
d76d79a (HEAD -> master, A) HEAD@{0}: reset: moving to d76d79a
d76d79a (HEAD -> master, A) HEAD@{1}: reset: moving to d76d79a
31a3585 HEAD@{2}: reset: moving to 31a3585
d76d79a (HEAD -> master, A) HEAD@{3}: merge A: Fast-forward
31a3585 HEAD@{4}: checkout: moving from A to master
d76d79a (HEAD -> master, A) HEAD@{5}: commit: a1
31a3585 HEAD@{6}: checkout: moving from master to A
31a3585 HEAD@{7}: commit (initial): m1
 
//回溯到A分支创建之前
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git reset --hard 31a3585
HEAD is now at 31a3585 m1
 
//创建B分支
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git checkout -b B
Switched to a new branch 'B'
 
//修改文件内容并提交
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git add .
 
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git commit -m "b1"
[B 69eb4b2] b1
 1 file changed, 1 insertion(+), 1 deletion(-)
 
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git reflog
69eb4b2 (HEAD -> B) HEAD@{0}: commit: b1  //提交B分支的修改
31a3585 (master) HEAD@{1}: checkout: moving from master to B  //创建B分支并切换
31a3585 (master) HEAD@{2}: reset: moving to 31a3585    //回溯到A分支之前
d76d79a (A) HEAD@{3}: reset: moving to d76d79a
d76d79a (A) HEAD@{4}: reset: moving to d76d79a
31a3585 (master) HEAD@{5}: reset: moving to 31a3585
d76d79a (A) HEAD@{6}: merge A: Fast-forward
31a3585 (master) HEAD@{7}: checkout: moving from A to master
d76d79a (A) HEAD@{8}: commit: a1
31a3585 (master) HEAD@{9}: checkout: moving from master to A
31a3585 (master) HEAD@{10}: commit (initial): m1
 
//推进到分支A合并到master位置
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git reset --hard d76d79a
HEAD is now at d76d79a a1

冲突消除

//前面已经合并了A分支,现在合并B分支,会发现更改部分冲突
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git merge B
Auto-merging test.txt
CONFLICT (content): Merge conflict in test.txt
Automatic merge failed; fix conflicts and then commit the result.

修改commit信息:git commit –amend

将上面的commit信息“消除冲突”修改为“merge-B”

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git commit --amend
[master f4d38a7] merge-B
 Date: Wed Jan 6 16:14:38 2021 +0800

这时会打开编程器

git及github的使用

按i键或者Insert键进行编程模式

git及github的使用

按ESC键进入命令模式,输入 :wq保存或者:q!不保存退出,查看reflog日志

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git reflog
f4d38a7 HEAD@{0}: commit (amend): merge-B  //已经修改了
1759d05 HEAD@{1}: commit (merge): 消除冲突
d76d79a (A) HEAD@{3}: checkout: moving from A to master

压缩记录:git rebase -i

git rebase 分支名:将当前分支的记录合并到其他分支中,使记录成线性化。

当我们在合并分支之前发现有拼写错误,这时我们再次提交会出现新的记录,但是拼写错误这条记录我们不希望出现在历史记录中,我们需要将这条记录和前一记录合并。

创建分支C,将test内容改为masterCc,其中c小写是错误的,我们要求大写,不过之前没有发现,现在已经提交了一次,如果修改后再提交就会有两条记录。

//git commit -am add与commit的合写
Administrator@User-14 MINGW64 /g/gitdemo (C)
$ git commit -am "c1"

六、向远程仓库GitHub推送

前面我们在github上已经建立了一个同名的gitdemo远程仓库,本地仓库与远程仓库名称尽量保持一致。

添加远程仓库:git remote add 标识符 远程仓库地址

此命令相当于给远程仓库设置一个别名(标识符),以后的操作直接在这个别名上操作。

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git remote add origin git@github.com:woodlum2017/gitdemo.git

将本地仓库中的内容推送到远程仓库:git push -u 标识符 远程分支名

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git push -u origin master
Enumerating objects: 18, done.
Counting objects: 100% (18/18), done.
Delta compression using up to 4 threads
Compressing objects: 100% (6/6), done.
Writing objects: 100% (18/18), 1.26 KiB | 215.00 KiB/s, done.
Total 18 (delta 1), reused 0 (delta 0)
remote: Resolving deltas: 100% (1/1), done.
To github.com:woodlum2017/gitdemo.git
 * [new branch]      master -> master
Branch 'master' set up to track remote branch 'master' from 'origin'.

-u参数:在推送的同时,将origin仓库的master分支设置为本地仓库当前分支的upstream(上游)当前分支与远程分支建立了对应关系,同时如果远程仓库没有master分支同时会创建。

a.在本地master分支中运行git pull命令从远程仓库的master分支获取内容;

b.在本地master分支中支行git push直接推送。

如果在其他分支中操作会产生错误,需要手动指定pull和push的仓库和分支。

Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git pull
Already up to date.
 
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git push
Everything up-to-date
 
==============手动推送=================
Administrator@User-14 MINGW64 /g/gitdemo (master)
$ git checkout B
Switched to branch 'B'
 
Administrator@User-14 MINGW64 /g/gitdemo (B)
$ git push origin B
Total 0 (delta 0), reused 0 (delta 0)
remote:
remote: Create a pull request for 'B' on GitHub by visiting:
remote:      https://github.com/woodlum2017/gitdemo/pull/new/B
remote:
To github.com:woodlum2017/gitde

七、从远程仓库GitHub中获取

获取远程仓库:git clone 远程仓库地址

执行git clone命令后我们会默认处于master分支下,同时系统会自动将origin设置成该远程仓库的标识符。

git branch -a //-a会显示本地和远程仓库的信息

新建一个文件夹gitdemo2

Administrator@User-14 MINGW64 /g/gitdemo2 (master)
$ git clone git@github.com:woodlum2017/gitdemo.git
Cloning into 'gitdemo'...
remote: Enumerating objects: 21, done.
remote: Counting objects: 100% (21/21), done.
remote: Compressing objects: 100% (7/7), done.
remote: Total 21 (delta 1), reused 18 (delta 1), pack-reused 0
Receiving objects: 100% (21/21), done.
Resolving deltas: 100% (1/1), done.
 
Administrator@User-14 MINGW64 /g/gitdemo2 (master)
$ cd gitdemo
 
Administrator@User-14 MINGW64 /g/gitdemo2/gitdemo (master)
$ git branch -a   //-a会显示本地和远程仓库的信息
* master
  remotes/origin/B
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
git及github的使用

获取远程仓库中的其他分支

git checkout -b B origin/B

创建一个新的本地分支B并切换,并获取远程仓库中的B分支数据

Administrator@User-14 MINGW64 /g/gitdemo2/gitdemo (master)

获取最新的远程分支git pull

假设当前分支为B,而远程上最新的分支是master,我们需要分支B中的数据是最新的。

Administrator@User-14 MINGW64 /g/gitdemo2/gitdemo (master)
$ git checkout B
Switched to branch 'B'
 
Administrator@User-14 MINGW64 /g/gitdemo2/gitdemo (B)
$ git pull origin master
From github.com:woodlum2017/gitdemo
 * branch            master     -> FETCH_HEAD
Merge made by the 'recursive' strategy.

关于多人协作,多人在同一个分支中操作,commit后push给远程仓库分支,如果多个人对同一个文件修改在push时会提示冲突,因此我们需要更加频繁的pull/push操作。

尽量不要多人修改同一个文件,每次分支修改前先pull仓库中的数据,修改后再push推送。
