Git Setup Basics

Git set-up for first time. Note for myself!

Start new project in Git

1. Create a new GitHub repository

  1. Log in.
  2. clike the + symbol, -> “New repository”
  3. Fill inn
    • Repository name,
    • Description
    • Visibility (not check README yet)
  4. Create repository

2. Clone the repo to machine

  1. Open terminal: 
    mkdir -p ~/Projects
cd ~/projects
  2. Clone repo 
    git clone https://github.com/yourusername/my-learning-log.git
  3. Go to the repo folder: 
    cd my-new-repo

3. Create new folders

Inside ~/Projects/my-new-repo:

mkdir Linux Nvim Python Statistics

Create new markdown file

echo "# Python Notes" > Python/README.md
echo "# Linux Notes" > Linux/README.md
echo "# Nvim Notes" > Linux/README.md
echo "# Statistics Notes" > Statistics/README.md

Copy over some old files

cp /path/to/file/file.md ~/Projects/my-new-repo

Or copy an entire folder:

cp -r [source_folder] [destination_folder]

or copy content of the folder:

cp -r ~/OldNotes/* ~Projects/my-new-rep/Python/

Be careful: files with the same name may be overwritten without warning!

4. State, commit and push changes

  • Let Git know we will track these new files and folders
  • Check git status
  • Commit changes with a message/text
  • Push the changes to GitHub
git add .
git status
git commit -m "Add category folders with starter README.md files"
git push

If token (password) is expired

Personal Access Token:

  1. Go to: https://github.com/settings/tokens
  2. Click “Fine-grained tokens”, or “Classic tokens” → Generate new token
  3. Fill in:
    • Name: something like Linux Git Token
    • Expiration: choose 30/60/90 days or “No expiration”
    • Repository access: Select Only select repositories or All repositories
    • Permissions:
      • check Contents > Read and Write
      • check pages > Read and Write (for webpage)
  4. Click Generate token
  5. Copy the token and store it safely (you won’t see it again). Paste it when Git asks for password.
Repository access:
[ ] No access (default)
[ ] All repositories
[✓] Only select repositories → (then pick your learning-log repo)

Permissions:
[✓] Contents: Read and Write

Save the tolken at once or it will be gone…

  1. To avoid entering the token everytime, cache it: 
    git config --global credential.helper store
  2. Push and paste the tolken. Git will remember it for future pushese 
    git push

    paste - done!

5. Get the latest changes on the PC

Direct to local repo folder

cd ~/Projects/thisporject

Then run

git pull

This will download and merge changes from GitHub into local files.

Summarise:

# pull latest changes 
git pull

# make changes

# commit changes
git add.
git commit -m "comment"

# push commit to Github
git push
