An Overview of Git

Abstract

Git is a distributed version control system used in software development that tracks modifications made to source code. Git, as opposed to centralized version control systems, enables several developers to collaborate independently on a single project by letting them maintain separate local repositories that are synchronized with a remote repository. Repositories, which hold the project's files and change history, are essential to Git's operation. A commit in a repository is a snapshot of the project at that specific point in time; each commit is distinguished by a distinct hash and is accompanied by an explanation message. Branches allow developers to work independently on various features or fixes. While other branches are used for development, the stable code is usually found in the main branch, also known as main (formerly master). Rebasing and merging are two ways that changes from branches can be merged into the main branch, each with a distinct function for preserving project history. A local copy of a repository is created by cloning it, and local changes are synchronized with a remote repository through pushing and pulling. The staging area serves as a buffer where modifications are made prior to commit. To manage and review these changes, use commands like `git add`, `git commit`, `git status`, and `git log`. Submodules, cherry-pick, and Git hooks are examples of advanced features that provide more customization and control. Well-known Git hosting services, such as GitHub, GitLab, and Bitbucket, offer platforms for code review, repository management, and tool integration, which promote collaborative development. Gaining proficiency with Git greatly improves development processes by facilitating effective teamwork and code management.
