Git for Linux - Install and Quickstart Guide

Here’s my workflow for working with Git and Github; the following is assuming working on Linux but working on Windows is fairly similar. Much of this is done seemlessly in Vscode if you want to avoid the command line: https://code.visualstudio.com/download, https://code.visualstudio.com/docs/sourcecontrol/overview.


  1. Open a terminal and type:
    sudo apt install git

Clone a Repository (repo)

  1. cd to where you want the repository cloned
  2. 1
    git clone https://github.com/yourUsername/yourRepository.git
    • could also be a repository from someone else
  3. enter username
  4. For password:
    1. follow the steps for creating a token: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token
    2. paste in your token for the password
    3. (optional) save the token to a .txt file or something for

Push your changes

  1. Mess around with some files in your local repository
  2. Push what you have to the origin: https://www.linode.com/docs/guides/how-to-install-git-and-clone-a-github-repository/
    1. cd to your github folder
    2. 1
       git add .
       git status
       git commit -a -m “message for commit”
       git push origin main

      Note: if you want to only commit certain files, then replae git add . with git add [insert file name here]

    3. Or if the last command didn’t work: git push origin master or git push origin main; essentially origin is your repository on Github.com, and master/main is the main branch
  3. type in username and password

Pull new changes

  1. cd to your github folder
  2. 1
    git pull origin main
  3. enter username
  4. enter token for password

Create New Branch

  1. git branch
    • This tells you what branch you’re currently on
  2. git checkout -b name-of-branch
    • this creates a new branch
  3. do your code modifications
  4. 1
    git add .
    git commit -m “title” -m “description”
    git diff name-of-branch
    • this shows the difference between the branch you just created
  5. git push

Merge origin/main changes into branch

Let’s say you want to pull changes to the origin/main branch to your branch:

  1. commit and push all changes to your current branch)
  2. 1
    git checkout main
    git pull
    git checkout {name of your branch}
    git merge main



remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.
fatal: Authentication failed for ‘https://github.com/uw-esolab/sf-learn.git/’

Solution: need a token: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token

Problem: you want to clone a fresh repo over your branch

git clone https://github.com/username/repo.git
Username: your_username
Password: your_token

*Solution: If you don’t care about the changes you made and want to pull the repository, type in: git reset –hard origin
