This outline covers everything you need to get started with git. The article clearly explain all you need whether you a beginner or trying to get some explanation on how to use git, you are in a right place to learn from. All key con-concept explained with examples.
1. Introduction to Git
- What is Git?
- Overview of Version Control Systems (VCS): A VCS helps manage changes to source code over time. Git is a distributed VCS, meaning every developer has a full copy of the project history.
- History and significance of Git: Created by Linus Torvalds in 2005, Git has become the most popular VCS due to its efficiency, speed, and distributed nature.
- Why use Git?
- Benefits of using Git for version control: Git allows multiple developers to work simultaneously, tracks changes, and supports branching and merging for flexible workflows.
- Comparison with other version control systems: Git vs. SVN, Mercurial, etc.
2. Getting Started with Git
- Installation
- Installing Git on Windows, macOS, and Linux: Step-by-step instructions for downloading and installing Git from git-scm.com.
3. Basic Git Concepts
- Repositories
- What is a repository? A repository is a directory that Git tracks.
- Creating a repository:
- Cloning a repository:
git clone <repository-url>
- Commits
- Understanding commits: A commit is a snapshot of your repository at a specific point in time.
- Creating commits:
git add <file>
git commit -m "Commit message"
- Viewing commit history:
- Branches
- What are branches? Branches allow you to work on different parts of a project simultaneously.
- Creating and switching branches:
git branch <branch-name>
git checkout <branch-name>
- Merging branches:
git checkout main
git merge <branch-name>
- Resolving merge conflicts: Git will prompt you to resolve conflicts manually.
- Tags
- What are tags? Tags mark specific points in history as important.
- Creating and listing tags:
git tag <tag-name>
git tag
4. Basic Git Commands
- Repository Commands
git init
: Initializes a new Git repository.
git clone
: Clones an existing repository to your local machine.
- File Operations
git add <file>
: Stages changes for the next commit.
git commit -m "message"
: Commits staged changes with a message.
git status
: Shows the status of changes.
git log
: Displays the commit history.
- Branching Commands
git branch
: Lists all branches.
git checkout <branch>
: Switches to the specified branch.
git merge <branch>
: Merges the specified branch into the current branch.
- Remote Repositories
git remote -v
: Shows the URLs of remote repositories.
git fetch
: Fetches updates from the remote repository.
git pull
: Fetches and merges updates from the remote repository.
git push
: Pushes local changes to the remote repository.
5. Working with Remote Repositories
- Understanding Remotes
- Adding and removing remotes:
git remote add <name> <url>
git remote remove <name>
- Tracking branches: Remotes track changes in branches from other repositories.
- Collaboration Workflows
- Forking and cloning: Create a copy of a repository on GitHub, then clone it locally.
- Pull requests: Propose changes to a repository.
- Reviewing and merging pull requests: Review and integrate changes from pull requests.
6. Undoing Changes
- Reverting Changes
- Undoing changes in the working directory:
- Reverting commits:
- Resetting
- Soft, mixed, and hard resets:
git reset --soft <commit>
git reset --mixed <commit>
git reset --hard <commit>
- Rebasing
- What is rebasing? Rebasing integrates changes from one branch into another.
- Interactive rebasing:
7. Advanced Git Features
- Stashing
- Saving and applying stashes:
git stash
git stash apply
- Managing multiple stashes:
- Cherry-Picking
- Applying specific commits from one branch to another:
- Submodules
- Working with submodules:
git submodule add <repository-url>
git submodule update --init
8. Git Workflows
- Centralized Workflow
- Feature Branch Workflow
- Gitflow Workflow
- Forking Workflow
9. Using Git with GitHub
- Setting up GitHub
- Creating a GitHub account: Register at GitHub.com.
- Linking Git and GitHub:
git remote add origin <repository-url>
git push -u origin main
- GitHub Features
- Issues and project boards: Track tasks and bugs.
- GitHub Actions: Automate workflows.
- Publishing Repositories
- Creating a new repository on GitHub: Use GitHub’s web interface.
- Pushing local repositories to GitHub:
- Collaboration on GitHub
- Forking repositories: Make a copy of a repository.
- Submitting pull requests: Propose changes.
- Code review process: Review and discuss proposed changes.
10. Git Best Practices
- Writing Good Commit Messages
- Guidelines for commit messages: Keep them clear and descriptive.
- Branch Naming Conventions
- Consistent and meaningful naming: Use descriptive names like
feature/add-login
.
- Frequent Commits
- Committing early and often: Helps track progress and find issues.
- Code Reviews
- Importance and best practices: Regular reviews improve code quality.
- Backup and Restore
- Ensuring data safety: Regularly push changes to remote repositories.
11. Troubleshooting Common Issues
- Resolving Merge Conflicts
- Step-by-step guide: Manually resolve conflicts and commit the changes.
- Common Error Messages
- Explanation and fixes: Research and resolve common issues.
- Using
git fsck
and git gc
- Checking and cleaning up repositories:
