1. Git基本 命令

设置用户名和邮件

 $ git config --global user.name "用户名"
 $ git config --global user.email "邮箱"

git status 命令用于查看在你上次提交之后是否有对文件进行再次修改。git status -s可以获得简短的输出结果A表示成功

 $ git status -s
 A  test.txt

git init 将文件夹初始化为git仓库

 $ git init
 Initialized empty Git repository in C:/Users/LDH/Desktop/wocao/.git/

git add . 将文件添加到暂存区

 $ git add .
 warning: LF will be replaced by CRLF in test.txt.
 The file will have its original line endings in your working directory

git commit -m “描述”将文件添加到版本库-m用来指定提交信息，这样提交只有一行-m "commit title" -m "commit description"

 $ git commit -m "添加了test.txt文件"
 [master (root-commit) 02959e8] 添加了test.txt文件
  1 file changed, 2 insertions(+)
  create mode 100644 test.txt

为什么要分add和commit两部？因为commit一次可以提交很多文件，所以可以多次add不同的文件

git diff test.txt可以查看文件被修改的具体内容

 LDH@DESKTOP-F8BM77J MINGW64 ~/Desktop/wocao (master)
 $ git diff test.txt
 warning: LF will be replaced by CRLF in test.txt.
 The file will have its original line endings in your working directory

git log --oneline --graph --oneline查看历史记录的简介版本，--graph查看分支结构

 $ git log --oneline --graph
 * 028c201 (HEAD -> master) 修改了test.txt文件1
 * cf6ce9f 修改了test.txt文件
 * 02959e8 添加了test.txt文件

git reset --hard id回退到以前的版本有了--hard会直接修改工作区的内容不加--hard只是修改暂存区

 $ git reset --hard cf6ce9f
 HEAD is now at cf6ce9f 修改了test.txt文件

git reflog可以看到已经删除的提交命令

 $ git reflog

 cf6ce9f (HEAD -> master) HEAD@{2}: commit: 修改了test.txt文件
 02959e8 HEAD@{3}: commit (initial): 添加了test.txt文件

git checkout test.txt把test.txt文件在工作区的修改全部撤销回到最近一次git add 或git commit的状态

 $ git checkout test.txt
 Updated 1 path from the index

git reset HEAD test.txt将test.txt从暂存区撤销，放回工作区

 $ git reset HEAD .
 Unstaged changes after reset:
 M       test.txt

git rm 文件名称 git commit 从版本库中删除文件

 $ git rm wocao.txt
 rm 'wocao.txt'
 $ git commit -m "删除wocao"
 [master 36a7ff6] 删除wocao
  1 file changed, 0 insertions(+), 0 deletions(-)
  delete mode 100644 wocao.txt

远程仓库

git remote -v查看是否有远程仓库

 $ git remote -v
 origin  https://github.com/ldh55/test.git (fetch)
 origin  https://github.com/ldh55/test.git (push)

git remote rm origin1删除名为origin1的远程库

 $ git remote rm origin1

1. 第一步：创建sshkey id_rsa是私钥不能告诉任何人 id_rsa.pub是公钥可以告诉任何人 $ ssh-keygen -t rsa -C "2815843603@qq.com"
2. 第二步：登陆github，打开设置，将id_rsa.pub中的内容添加到ssh key中
3. 关联远程库，origin是远程库的名字，默认 $ git remote add origin https://github.com/ldh55/test.git
   error: remote origin already exists.
4. 将本地库的内容推送到远程库上 $ git push origin master

   Counting objects: 100% (4/4), done.
   Delta compression using up to 8 threads
