install

check your installation using command line( like Git CMD, Git Bash):

git --version

windows 10

official website:

Git for Windows or Git - Downloads (git-scm.com)

you can refer to( remember your installation directory of git if you want to set it as environment variable later):

Windows系统Git安装教程（详解Git安装过程）_IT技术实战-CSDN博客

*set {installation directory}\cmd\git.exe as environment variable in Path if you want to use it in other command line like cmd.exe

Ubuntu/Debian

For the latest stable Git version in Ubuntu/Debian:

sudo apt-get install git

basic use

you can create a new repository or clone a existing one

create new repository

create a local repository(版本库), a directory of ‘.git’, in the ‘directory ‘ using Git Bash :

git init [<directory>]

clone existing repository

clone a existing repository in ‘directory ‘ using Git Bash:

git clone <repository> [<directory>]

Configure repository

check your configuration:

git config --list

set your information for local repository before “commit”:

git config --global user.name "<name>"
git config --global user.email <email>

more configuration, refer to Git 创建仓库 | 菜鸟教程 (runoob.com)

work with repository

more use, refer to Git 仓库基础操作 - Gitee, Git 基本操作 | 菜鸟教程 (runoob.com), Git 远程仓库(Github) | 菜鸟教程 (runoob.com), Git Gitee | 菜鸟教程 (runoob.com).

*you can place your remote repositories in Github, preparation see [prepare with Github](# prepare with Github).

checkout

refer to git checkout 命令详解,

Git GUI use

refer to 使用Git 总结-msysGit与GitHub 使用_荒野之鹰-CSDN博客 or Windows平台下Git的安装msysgit与配置_睡得香吃得好胆子大的专栏-CSDN博客

prepare with Github

configure your account SSH Key, refer to 使用 SSH 连接到 GitHub - GitHub Docs

Create SSH Key

check existing keys:

ls -al ~/.ssh

*”~/.ssh” is the default directory of SSH keys.

otherwise, create a SSH key for your device using Git Bash:

ssh-keygen -t [algorithm] -C "<personal code, like a email>"

*algorithm(optional): rsa [-b 4096], ed25519(recommend).

Configure ssh-agent

ssh-agent stores unencrypted keys in memory( for Unix-like OS) and communicates with SSH clients using a Unix domain socket

run ssh-agent using Git Bash:

# Windows
eval `ssh-agent -s`
# Linux
eval "$(ssh-agent -s)"

check keys loaded in the ssh-agent:

ssh-add -l

if none, add SSH private key to the ssh-agent:

ssh-add <SSH private key>

*SSH private key example: ~/.ssh/id_ed25519

switch off the agent using Git Bash, refer to ssh agent详解 - 知乎 (zhihu.com):

ssh-agent -k

*if not use agent, there maybe warnings, solution refer to: Win10 从零搭建Git环境_feng991254的专栏-CSDN博客 or win10 git环境搭建_ydf8525的专栏-CSDN博客

Add SSH key to Github

1. open responding SSH public key with a editor like Notepad, then copy the contents of the .pub file to your clipboard,

*SSH public key example: ~/.ssh/id_ed25519.pub, so you can print it in line:

# windows & 
cat ~/.ssh/id_ed25519.pub
# Linux
sudo apt-get update
sudo apt-get install xclip
xclip -selection clipboard < ~/.ssh/id_ed25519.pub

2. go into your own Github setting -> SSH and GPG keys, and create a new SSH key,

then give a name of the key filling in the “title”, and paste the SSH public key contents into the “Key” field.

3. test SSH connection:

ssh -T git@github.com

if something wrong, baidu or google.

prepare with Gitee

configure your account SSH Key

Create SSH Key

check existing keys:

ls -al ~/.ssh

*”~/.ssh” is the default directory of SSH keys.

otherwise, create a SSH key for your device using Git Bash:

ssh-keygen -t [algorithm] -C "<personal code, like a email>"

*algorithm(optional): rsa [-b 4096], ed25519(recommend).

Add SSH key to Gitee

1. open responding SSH public key with a editor like Notepad, then copy the contents of the .pub file to your clipboard,

*SSH public key example: ~/.ssh/id_ed25519.pub, so you can print it in line:

cat ~/.ssh/id_ed25519.pub

2. go into your own Gitee setting -> SSH keys, then fill the blank and add a new SSH key: give a name of the key filling in the “title”, and paste the SSH public key contents into the “Key” field.
3. test SSH connection:

ssh -T git@gitee.com

if something wrong, baidu or google.
