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 -b to create a new branch and git checkout to switch between branches.
Use git merge to 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 branch to list all branches.
Use git branch -d to delete a branch.
