Study Notes
Git and GitHub Fundamentals
- Git is a version control system - it tracks changes made to code files.
- GitHub is a web-based platform for storing and managing code using Git.
- Git works similarly to a bank account - it tracks deposits and withdrawals, representing changes to files.
Using Git
- Git Init: Initialize a new Git repository within a directory.
- Git Clone: Create a local copy of a remote repository.
- Git Status: View the current state of the working directory (files modified but not saved) and the staging area (files marked for committing).
-
Git Add: Stage changes to specific files or all changes with
git add .. - Git Commit: Save staged changes to the local repository with a descriptive message.
- Git Push: Upload local commits to a remote repository on GitHub.
Managing Code Changes
- Git Branches: Create isolated development environments to work on specific features without affecting the main codebase.
-
Creating a new branch: Use
git checkout -b <branch_name>. -
Merging branches: Combine changes from one branch into another with
git merge <branch_name>. - Pull Requests (PR): Request to merge changes from a branch into another, enabling code review and collaboration.
Handling Conflicts
- Merge Conflicts: Occur when Git encounters conflicting changes in two branches that it can't auto-resolve.
- Resolving merge conflicts involves manually choosing changes to keep from both branches using a code editor.
Undoing Changes
-
Git Reset: Undo the last commit using
git reset HEAD~1. - Git Log: View all commits in the repository's history.
Forking Repositories
- Forking creates a personal copy of someone else's repository on GitHub, allowing you to experiment or contribute without affecting the original.
Working with GitHub
- GitHub Repository: A project container on GitHub that houses all the code, branches, issues, and other project-related data.
- GitHub Account: Required to use GitHub - create one with a personal email address.
- Public or Private Repositories: Public repositories are visible to everyone, while private repositories are restricted to collaborators.
General Workflow
-
Initialize a local repository using
git init. -
Clone a remote repository using
git clone. -
Make changes to files and check their status with
git status. -
Stage changes with
git add. -
Commit staged changes with
git commit -m "message". -
Push changes to a remote repository with
git push origin main. - Create branches for new features and merge them back into the main branch.
- Use pull requests for collaborative code reviews.
