Study Notes
Git Version Control System
- Provides a long-term change history of every file, storing every change made by individuals.
- Enables collaboration, history tracking, and allows developers to create separate branches without affecting the main branch.
Benefits of Git
- Supports offline work and keeps a complete history of changes made, including who and when.
- Allows multiple developers to work on the same project.
- Scalable and works with small and large projects.
Git Creation and Features
- Created by Linus Torvalds in 2005 (not 2015).
- A distributed system, where every developer's working copy of the code is also a repository that can contain the full history of all changes.
- Written in C language.
- Easy to learn, hard to master.
Gitignore
- A configuration file that specifies directories and files to be ignored by Git.
- Do not store credentials in the code, use environment variables instead, and add them to the gitignore file.
Git Commands
git status: shows the current state of the repository.git diff: shows the differences between the current and previous versions.git checkout: switches to a different branch or creates a new one.git checkout -b: creates a new branch and switches to it.git commit -a -m: commits all changes with a message.git log: shows the commit history.git rm: removes files from the repository.
Branching and Merging
- Branching allows multiple developers to work on the same project without affecting the main branch.
- Merging allows changes from one branch to be incorporated into another branch.
- Use
git checkout -bto create a new branch andgit checkoutto switch between branches. - Use
git mergeto merge changes from one branch into another.
Hotfixes and Branching
- When a hotfix is needed, create a new branch from the production branch, make the changes, and then merge it back into the production branch.
- After merging, delete the hotfix branch.
Commit Messages
- Commit messages should be meaningful and concise.
- Try to make them short and understandable.
Best Practices
- Use separate branches for new features and bug fixes to avoid messing with the main branch.
- Try to avoid using the main branch for development.
- Use
git branchto list all branches. - Use
git branch -dto delete a branch.
