Mastering the Basics of Git: A Step-by-Step Guide

Discover git as a distributed version control system that tracks history, enables conflict-free collaboration, and supports branching, merging, and pull requests for open source and ci/cd workflows.

Install git on Windows, macOS, and Linux, verify with git --version, and use Git Bash on Windows or Homebrew on macOS for a streamlined version control workflow.

Explore the basic structure of Git, including the working directory, staging area, repository, commits, and branches, and learn essential commands like git status, git add, and git commit.

Learn to create a git repository, stage and commit changes with descriptive messages, view history with git log, and manage file modifications and deletions on the main branch.

Initialize a new repository with git init, create files with touch, add and commit, check status, and review history with git log; learn to undo changes with git checkout.

Assess your understanding of git fundamentals with nine multiple-choice questions, explanations after each answer, covering distributed version control, git version, init, add, commit, log, checkout, diff, and revert.

Review core Git concepts, including blobs, trees, commits, and references like head, branches, and tags, and recap the working directory, staging area, and repository structure.

Perform a practical, hands-on setup: create a repository with mkdir and cd, initialize Git to reveal the hidden .git directory, then configure .gitignore to exclude temp.log and *.temp.

Stage changes with git add ., verify git status, commit with git commit, and amend messages with --amend. Review history with git log and selectively stage changes with git add -p.

Learn to undo changes and revert commits in git using checkout to restore files, plus reset --soft to roll back commits while preserving work, and git revert to reverse changes.
