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.

• Basic Configuration
• Setting up your Git environment:
  use below config to set your details

   

  git config --global user.name "Your Name"


  git config --global user.email "your.email@example.com"


   

  Configuring default text editor:

   

  git config --global core.editor "code --wait"


   

  Checking configuration settings:
   
  git config --list


3. Basic Git Concepts

• Repositories
  • What is a repository? A repository is a directory that Git tracks.
  • Creating a repository:
     

    git init

     
  • 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:
     

    git log

• 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:
     

    git checkout -- <file>

  • Reverting commits:
     

    git revert <commit>

     
• 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:
     

    git rebase -i <commit>


7. Advanced Git Features

• Stashing
  • Saving and applying stashes:
     

    git stash
git stash apply

     
  • Managing multiple stashes:
     

    git stash list

     
• Cherry-Picking
  • Applying specific commits from one branch to another:
     

    git cherry-pick <commit>

     
• Submodules
