Study Notes
Introduction to Git
- Git is a distributed version control system crucial for tracking changes in files over time, enabling collaborative work and efficient version reverting.
- Its crucial role in software development stems from its ability to handle multiple people working concurrently on a project.
- Git stores snapshots ("commits") of the project's state, not just change lists, optimizing branching and merging.
- A repository ("repo") is the central storage for the project's files and commit history.
Key Git Concepts
- Repository (repo): A central storage location for project files and commit history.
- Commit: A snapshot of the project at a particular point in time, accompanied by a descriptive message.
- Branch: A separate line of development that can be merged later into the main branch.
- Staging Area: An intermediate area where changes are prepared for commit.
- Working Directory: The directory where the current version of project files resides.
Git Commands
-
git init: Initializes a new Git repository. -
git clone <repository URL>: Creates a local copy of a remote repository. -
git add <file>: Stages changes for the next commit.git add .stages all changes in the current directory. -
git commit -m "Commit message": Records changes with a message. -
git status: Displays the state of the repository (tracked/untracked files, etc.). -
git log: Shows the commit history.git log --onelineis a summarized view;git log --graphvisualizes branches. -
git branch: Manages branches.git branch <branch_name>creates a new branch.git checkout <branch_name>switches to a branch. -
git merge <branch_name>: Merges changes from a branch into the current one. -
git push <remote name> <branch name>: Uploads local commits to a remote repository. Example:git push origin main. -
git pull <remote name> <branch name>: Downloads commits from a remote repository. Example:git pull origin main. -
git fetch origin: Downloads commits from a remote, but does not merge. -
git remote add origin <repository URL>: Adds a remote repository.originis the common name, but any name will work.
GitLab
- GitLab is a web-based Git repository manager with integrated applications like CI/CD, project management, and issue tracking.
- Projects use a repository structure, offering features similar to GitHub for collaboration and code management, but with integrated CI/CD capabilities.
- Projects often include wikis and issues for task and communication management.
- The unified platform simplifies management of all repository aspects.
GitHub
- GitHub is a web-based platform hosting Git repositories, supporting features such as issue tracking, code review, and collaborative development.
- It's widely used for sharing and managing code, and supports public & private repositories for collaboration.
- Tools like pull requests simplify code review and merging.
- GitHub prioritizes hosting and managing Git repositories in a cloud-based environment.
Git, GitHub, and GitLab Interconnection
- Git is the local version control system; GitLab and GitHub are remote repository systems.
- Git commands manage your local repository, while
git pushandgit pullconnect it to remote repositories. - Cloning a repository creates a local copy for working offline.
Basic Git Workflow
- Create a new repository with
git init. - Create a new branch with
git branch <branch name>. - Switch to the new branch with
git checkout <branch name>. - Make changes to your files.
- Stage the changes with
git add .. - Commit the changes with
git commit -m "your commit message". - Push the changes to the remote repository with
git push <remote_name> <branch_name>.
