1. 为什么要使用 Git & GitHub

2. 什么是版本控制？

3. 安装 Git、初始化仓库并做最简单的配置

git --version

mkdir learn_git

cd learn_git

ls -al

git init

ls -al

git config --global user.name "wuyong"

git config --global user.email [email protected]

git config --global --list

4. 在 Windows 系统上安装 Git

5. 完成一个最简单的 Git 操作流程：工作区、暂存区和仓库

git status

pwd

git status

git add learn_git.html

git status

git commit -m "create learn_git.html"

git status

git add .

git status

git commit -m "web1.0"

git add learn_git.html

git commit -m "web2.0"

git log

6. 将本地仓库同步到远程 GitHub 仓库

HTTPS

https://github.com/wuyong/learn_git.git

SSH

[email protected]:wuyong/learn_git.git

…or create a new repository on the command line

echo "# learn_git" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin [email protected]:wuyong/learn_git.git
git push -u origin master

…or push an existing repository from the command line

git remote add origin [email protected]:wuyong/learn_git.git
git push -u origin master

Checking for existing SSH keys

ls -al ~/.ssh

Generating a new SSH key and adding it to the ssh-agent

ssh-keygen -t rsa -b 4096 -C "[email protected]"

eval "$(ssh-agent -s)"

open ~/.ssh/config

touch ~/.ssh/config

open ~/.ssh/config

Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_rsa

ssh-add -K ~/.ssh/id_rsa

Adding a new SSH key to your GitHub account

pbcopy < ~/.ssh/id_rsa.pub

Testing your SSH connection

ssh -T [email protected]

push an existing repository from the command line

git remote add origin [email protected]:wuyong/learn_git.git
git push -u origin master

git add learn_git.html

git commit -m "web3.0"

git push -u origin master

git log
