Git and GitHub Flashcards
What does Git do?
It tracks the changes you make to files (AKA a version control system).
*you have a record of what has been done
*you can revert to specific versions
*allows changes by multiple people to all be merged into one source.
Three basic Git commands
*git init (this creates or initializes an empty git repository)
*git add xxxx adds file to the staging area. Use a . to add all files.
*git commit -m ‘x’ where x = a description of your update
What’s the Git command for looking at your version history?
git log
*This shows a repository’s history, i.e. all previous saved changes
*use when you need to find a specific version of a project
*use to figure out what changes will be introduced by merging in a feature branch.
What’s the git command for going into a previous version of your code?
git checkout x
(where x is the code from git log. This code is a ‘commit hash’)
What’s the difference between Git and Github?
Git is stored on your computer. Github is a website where you can put a git so other people can access it.
What is a repository in Git?
Another name for a folder. Nothing more.
What is a commit in Git?
*a snapshot or milestone along the timeline of a Git project.

a pull. The command is –git pull origin master– to pull the whole thing
