Install Git and Set up Github

This page describes how to set up a github account and create your own repository, see this guide for how to pull from fan’s Math4Econ or other repositories.

Install and Create a Repo on Github

Replace my email below

1. Install GIT
2. install putty
3. Install Atom as a git/github friendly editor
4. Set up an account on GITHUB
5. Create a new repository under your account’s repository tab, for example: https://github.com/FanWangEcon?tab=repositories; choose to Initialize this repository with a README.

Set up Local Security to Pull and Push to Github

1. Open up git bash and enter the command below.
   • when prompted “enter file in which to save the key”, press enter, this will automatically put the rsa key you generate in the default folder below under ~/.ssh/ with file name id_rsa.pub.
   • when prompted for passphrase, enter the password you like when you see a key icon. You can’t see the password that you’ll type.

     ssh-keygen -t rsa -C "wangfanbsg75@live.com"
     

2. Copy the rsa key you just created (use cat instead of clip for mac users).
   • You can also go to the .ssh folder under your root directory and find the id_rsa.pub file directly
   • If you don’t know where your root is, open up git bash, type in cd ~/, and then type in pwd, what appears on the screen is your root directory

     clip < ~/.ssh/id_rsa.pub
     

3. Go to your github account, under user settings, click on SSH and GPG Keys, choose to create a New SSH Key, paste the text we got from id_rsa.pub in the space for key, and provide a title.
4. Then, also do this for Windows:

   cd ~/.ssh; ls -l
   chmod 700 id_rsa
   

   For MacOS and Linux users, follow the reference

Local and Github Sync Pull and Push

Pull

We initialized our new repository on github.com with a README.md file, so we can pull what we created to the local computer now that we have the same id_rsa.pub key on github as well as locally.

Enter the passphrase you generated previously when prompted.

In git bash, do the following:

mkdir ~/ClusterEstimate
cd ~/ClusterEstimate
git init
git config --global user.name "Fan Wang"
git config --global user.email wangfanbsg75@live.com
git config --list
git remote add github git@github.com:FanWangEcon/ClusterEstimate.git
git pull github master

Push

Make some changes in your README.md file, and now you can push back.

If you use Atom, the files you have edited will appear yellow, and new files you have created will appear green.

1. git add -A: this is the same as clicking stage all in the git pane in Atom
2. git commit -m “commit message”: this is the same as writing a commit message and clicking commit to master under Atom
3. git push -u github master: this pushes the local changes to github, the same as clicking on push in Atom
4. do these steps first under git bash once, afterwards, you can click on fetch and pull inside atom without having to go to git bash

git add -A
git commit -m "commit message"
git push -u github master
