What is GitHub or Coding

Both of them is a software development platform which is pretty powerful. Coding's server is located in China, so it will be loaded faster than GitHub if you are in China, while Github's server is in the United States. We can put our code to those platforms so that we can have a good command of our projects such as reviewing your code, retrieving an old version of our project and so on. If you want to have a full understanding of GitHub, here is a Wikipedia Link about GitHub.

Git

Git is a version control system for tracking changes in computer files and coordinating work on those files among multiple people. It is primarily used for source code management in software development,
but it can be used to keep track of changes in any set of files. As a distributed revision control system it is aimed at speed, data integrity, and support for distributed, non-linear workflows.

Install git

Choose your system to install it.

Linux

Running the following command in the terminal.

• Ubuntu/Deepin/Debian/Linux Mint
  sudo apt-get install git
• Fedora, CentOS 或 RHEL
  sudo yum install gitorsudo dnf install git
• Archlinux
  sudo pacman-S git
• OpenSUSE
  sudo zypper install git
• Gentoo
  emerge --ask --verbose dev-vcs/git

In addition to installing it in your terminal, you also can install it through compiling its source code.
Before you compile git, you should download its dependencies packages.

• Debian, Ubuntu 或 Linux Mint

sudo apt-get update
sudo apt-get install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev asciidoc xmlto docbook2x

• Fedora, CentOS 或 RHEL

$ sudo yum update
$ sudo yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

Download source code and compile

$ wget https://codeload.github.com/git/git/zip/v2.14.2
$ unzip git-2.14.2.zip
$ cd git-2.14.2
$ make prefix=/usr/local/git all 
$ make prefix=/usr/local/git install

Add git's path into environment variable
sudo vim /etc/profile
And then add the following line into the last line of the file.
export PATH=/usr/local/git/bin:$PATH
Make it work
source /ect/profile

Window

Download git for windows from its official website.
After installing, you can use it in the terminal.

Deploy your project to the Github or Coding

After the installing procedure, you can use it now.

Configure your git

set your personal information so that others can recognize you

git config --global user.name “your name”
git config --global user.email “email”

Using SSH

If you don't want to type account and password every time you push your project to Github, you can use SSH.
In the page, click the new SSH key button to create an SSH key.
If you are using Linux, open your terminal. Open Git Bash if you are using Windows. Then type ssh-keygen -t rsa -C "your_email".

After doing this, you can find two files(id_rsa id_rsa.pub) are generated in the .sshdirectory.Copy the content of id_rsa.pub to github.
Type ssh -T git@github.com to test whether it is work or not.(see more information about generating SSH Key.)

Github

First, create a repository for your project in the Github.

You can choose your repository to keep public or private.The latter need to pay, and the former is free. You can add a short sentence to describe your project in the Description column.It is optional for you to create a Readme file which aims to tell other what is your project and how to use your project. After creating a new repository, you will see the following picture.

Initialize your repository tip

Create a new repository

cd <target directory> //for example `cd /home/demo`
git init              //In the directory initialize a local repository
git add README.md //If you have a README.md file, you can add it to the repository.
git commit -m "first commit" //This command tends to commit your project into the local repository. Write your change in your project with the braces.
git remote add origin https://github.com/strivexj/demo.git // Establish a connection between your local repository and the Github's repository
git push -u origin master //This command tends to commit your project to Github's repository. -u means set upstream, you only need to add it in the first time.

Or push an existing repository from the command line

If you have a local repository, you can use the following command to directly add your project to the Github's repository you just created.

git remote add origin https://github.com/strivexj/a.git
git push -u origin master

After running git push -u origin master , it will pop up a window, or in the terminal to ask you to type in account and password, you should type your Github's account and password.

Git common command

git init
git add [filename] // If you want to add all file, you can use `git add .`
git commit 
git push   //such as git push origin master, replace origin with your repository's branch name you have set.
git log   //show commit logs
git status //show the working tree status
git fetch //download objects and refs from another repository
git pull //fetch from and integrate with another repository or a local branch
git remote set-url origin url //if you want to change your remote repository, you can use this command

Coding

The procedure of Coding is the same as Github, if you have understood how to use Github, you can do the same to deploy your project to the Coding platform.
