Some git commands are powerful but risky because they can rewrite history, move branch tips, or discard work. Used carelessly, they break open reviews, hide teammates’ changes, and make it hard to trace what actually shipped. Treat history edits as exceptional: prefer additive fixes for shared code...
HEAD is Git’s pointer to the snapshot you’re currently working on—the bookmark of your checkout. Most of the time, HEAD points to the tip of a branch (like master or main). When you commit, HEAD (and that branch) advance to the new commit...
Git stores your project as a graph of immutable objects. At the leaves are blobs: raw file contents with no filenames attached. Trees sit above blobs and act like directories; a tree is just a list that maps a filename and a mode to either another tree (subfolder) or a blob (file). Commits point to ...
Git branches are lightweight names that point to commits. Think of them as parallel timelines: you can try ideas on a branch without touching main, then merge back when you’re happy...
Before choosing a branching strategy, it helps to decide what you’re optimizing for: speed, safety, or simplicity. Different teams and projects lean different ways—startups with small codebases won’t work the same as larger, multi-repo setups. This overview lays out the options and how to adapt them...
Running your own Git server is about owning your source of truth. Your repos live where you decide, under rules you set, at a pace you control. That means you decide who can read and write, how code moves to production, and how the system grows as your team and projects grow. It’s pure Git under the...
Git is a version control system (VCS) created by Linus Torvalds, the same person who developed the Linux kernel. It’s a tool for tracking changes to files over time, mainly used in software development but useful for any project that involves evolving files...
git archive is your clean-room packager. It snapshots exactly what Git tracks at a commit—no .git folder, no stray build junk, no temp files. This means you can hand someone a tidy source bundle or ship code to a server without dragging history along...
The three core actions you’ll perform most often in Git are staging, committing, and undoing changes...
Tags mark exact commits. They’re perfect for releases, rollbacks, changelogs, and CI/CD triggers. Unlike branches, tags don’t move—ever—so you can always point to the exact build you shipped...
Git offers several ways to inspect and understand what has changed in your codebase. Mastering these commands helps you monitor progress, spot issues early, and keep your project history organized. Think of it like reading the "track changes" feature in a word processor—but for your entire code proj...
In Git, you might accumulate multiple small commits over the course of developing a new feature, fixing small bugs, or refactoring code. While these incremental commits are crucial during active development, they can clutter the project history in the long term. This clutter becomes especially evide...
When managing software projects, organizations often need to choose between two distinct codebase structuring strategies: monorepos and multirepos. This decision isn’t just about where code lives—it affects collaboration, tooling, versioning, and even deployment practices. When you’re starting out o...
When collaborating on a project, it's essential to keep your local repository updated with changes made by others in the team. Git provides powerful commands to facilitate this process...
Git is a powerful and widely used version control system that helps you manage code changes, work with others, and keep projects safe. Think of it as a digital timeline you can jump back to whenever something goes wrong. Here are some straightforward reasons to learn Git...
Git is a powerful tool, but its complexity often puzzles newcomers. Let’s break down some typical areas where users get tripped up in simpler terms...
In Git terminology, "stashing" refers to temporarily saving changes that are not ready to be committed. This allows you to switch branches or make other changes without losing your work...
