What is a git repository?

• The .git directory
• A set of commit objects
• A set of references to commit objects (“heads”)

What is a commit object?

• A set of files
• References to parent commit objects

What is a head?

• A reference to a commit object
• There is a default head in every repository. It's called master
• A repository can have any number of heads
• There will always be one and only one currently active head

Let's create a Repository

git init or simply git init

Create a file, stage it and commit it

• cd <newfoldername>
• touch pyladies.py
• git status

It's “Untracked”

• git add “pyladies.py”
• git status
• git commit -m “Initial Commit”
• git status
• git log

The three commands you'll use over and over

• git add .
• git commit -m “Fix infinite loop”
• git push origin master

Now let's get set up to share it online

create a repo on github's website (or see pro-tip below)

git remote add origin [email protected]:<githubusername>/<reponame>.git

Pro-tip:

If you have curl installed, you can create a github repo from your command line. Check to see if curl is installed by typing curl --manual. The curl command for creating a github repo is curl -u '<githubusername>' https://api.github.com/user/repos -d '{"name":"<reponame>"}'

Edit the file, stage, commit, push

• xdg-open pyladies.py
• git add .
• git commit -m “Add some content”
• git push origin master

Branching & Merging

• git checkout -b mybranch
• git branch
• git checkout master
• git merge mybranch

Working with someone else's repo

• Make a copy:

Git clone [email protected]:<githubusername>/<reponame>.git

• Receive changes:

Git fetch

Git pull origin master

• Upload your changes:

Git push origin master
