AWS DevOps: Fundamentals of Git: A Beginner's Guide
DevOps is a cultural and technical movement
that emphasizes collaboration, automation, and integration between development
and IT operations teams. The goal is to shorten the software development
lifecycle, deliver features faster, and enhance the quality of
applications. -DevOps Training
Git is a powerful and widely used version control system that allows developers to track changes in their codebase, collaborate with others, and manage their projects effectively. Whether you're a software developer, a designer, or anyone working on digital projects, understanding the fundamentals of Git is essential. In this article, we'll explore the basic concepts of Git to help you get started.
What is Git?
Git is a distributed version control system
(DVCS) created by Linus Torvalds in 2005. It is designed to keep track of
changes made to files and directories in a project. Unlike traditional
centralized version control systems, Git operates locally on your machine,
making it faster and more flexible.
Repositories
In Git, a repository (or repo) is the core
concept. It's a directory where your project's files and version history are
stored. Repositories can be local (on your computer) or remote (hosted on
platforms like GitHub, GitLab, or Bitbucket). Creating a local repository is as
simple as running git in it in your project's directory. - DevOps

Commits
A commit represents a snapshot of
your project at a particular point in time. Each commit has a unique identifier
(a hash) and contains changes to one or more files. Commits are accompanied by
commit messages, which describe the changes made in that commit. To create a
new commit, you use the git commit command. - DevOps

Branches
Branches allow you to work on different
aspects of your project simultaneously. The default branch is usually named
"master" but can be changed to a more descriptive name. You can
create new branches with git branch and switch between them using git checkout
or git switch. -DevOps Online

Pull and Push
When working with remote repositories, you
often need to fetch changes from the remote server (pull) or send your changes
to it (push). The git pull command combines fetching and merging changes from
the remote repository, while git push uploads your local changes to the remote
repository.
Merge
and Rebase
Merging combines changes from one branch into
another, creating a new merge commit. Rebase, on the other hand, moves or
combines a sequence of commits onto a new base commit. Both techniques are used
to integrate changes from one branch into another, but they have different
implications for commit history.

Conclusion
These are the fundamental concepts of Git, and
they provide a solid foundation for version control and collaboration in
software development and other digital projects. As you become more comfortable
with Git, you can explore advanced features and workflows to optimize your development
process. Git's popularity and versatility make it an essential tool for modern
software development, and mastering its fundamentals is a valuable skill for
anyone in the field.
