Study Notes
Introduction to Git
- Git is a distributed version control system, meaning it doesn't rely on a central server. Each user's local repository holds a complete project history.
- This enables offline work and strong backups.
- Git is primarily for code, but functions for any project needing version control.
Key Concepts
- Repository: A directory storing project files and version history.
- Working Directory: The current project folder on your computer.
- Staging Area (Index): A temporary area for preparing files to be added to a commit.
- Commit: A permanent snapshot of the project at a specific time. It records changes made.
- Branch: A separate development line for features or fixes. Changes merge back to the main branch.
- Remote Repository: A copy of the project's repository on a server. Facilitating collaboration.
- Clone: Making a local copy of a remote repository.
- Push: Uploads local repository changes to remote.
- Pull: Downloads remote repository changes to local.
- Merge: Combining changes from one branch to another.
- Stash: Temporarily saving uncommitted changes for later use, aiding branch switching.
Basic Git Commands
-
git init: Initializes a new Git repository. -
git status: Displays tracked and untracked files. Shows working directory and staging area changes. -
git add <filename>: Stages a file.git add .stages all changes. -
git commit -m "<message>": Creates a commit. The message helps explain changes. -
git branch <name>: Creates a branch. -
git checkout <name>: Switches to a branch. -
git push <remote> <branch>: Uploads a local branch. -
git pull <remote> <branch>: Retrieves remote changes. -
git log: Displays commit history. -
git diff: Shows changes between versions. -
git merge <branch>: Merges changes.
Git Workflow
-
New Branch:
git branch new_feature;git checkout new_feature. -
Changes: Add changes to the staging area:
git add .. -
Commit:
git commit -m "Added new feature". -
Push:
git push -u origin new_feature. -
Pull Updates:
git pull origin master. Keeps local aligned with remote. - Conflicts: Git helps merge remote and local changes.
-
Continue Work:
git pushto the remote completed branch. -
Merge back to Master:
git checkout master,git merge new_feature, thengit push origin master.
Advanced Git Topics
- Rebasing: Rewrites commit history, useful for feature branches.
- Cherry-picking: Selects specific commits and applies them elsewhere.
- Remote Branches: Support collaboration and remote repository sharing.
- Git Hooks: Scripts triggered by Git events.
Collaboration Using Git
-
Cloning:
git clone <repository URL>. Creates a local copy. - Pushing/Pulling: Synchronizes local and remote repositories. Enhances collaborative development.
- Branching/Merging: Enables parallel feature development and seamless integration.
- Resolving Conflicts: Git's tools assist in merging file changes made by multiple users.
Useful Git Tips
- Use clear commit messages.
- Commit frequently.
