General Knowledge Coming Soon

Git Version Control

The course teaches Git fundamentals, remote repository handling, branching and merging, advanced recovery, and collaborative workflows, enabling learners to manage codebases efficiently in team environments.

Who Should Take This

It is ideal for new developers, QA engineers, or project leads who have little or no experience with version control and need to contribute to shared codebases. Participants seek to master daily Git commands, adopt branching strategies, and confidently recover from mistakes while collaborating in agile teams.

1 Git Fundamentals

2 topics

Repository Basics and the Three Areas

Initialize a Git repository with git init and explain the three-area model (working directory, staging area/index, repository), describing how changes flow from modified files through staging to committed snapshots.
Use git add (files, directories, -p for hunks), git commit (-m, --amend), git status, and git diff (unstaged, --staged) to stage, commit, and inspect changes in the working directory and index.
Write meaningful commit messages following conventional formats (imperative mood, 50-char subject, blank line, body), and explain why atomic commits (one logical change per commit) improve history readability and bisectability.
Configure .gitignore with glob patterns to exclude build artifacts, dependencies, and environment files, and set up git config for user identity (user.name, user.email), default editor, and common aliases.

History and Inspection

Use git log with options (--oneline, --graph, --all, --author, --since, --grep, -p) and git show to inspect commit history, view diffs between commits, and understand the directed acyclic graph (DAG) of commits.
Use git diff to compare the working directory, staging area, and any two commits or branches, interpreting unified diff output format (hunks, +/- lines, @@ headers) to understand what changed.
Use git blame to identify the commit and author responsible for each line in a file, and apply git bisect (start, good, bad, reset) to binary-search for the commit that introduced a bug.

2 Remote Repositories

1 topic

Cloning and Remote Operations

Clone repositories with git clone, manage remotes with git remote (add, remove, -v), and explain the relationship between local branches and remote-tracking branches (origin/main).
Use git push and git pull (fetch + merge) to synchronize with remotes, set upstream tracking with -u, and explain the difference between git fetch (safe download) and git pull (download + merge).
Resolve push rejections caused by divergent histories, choosing between git pull --rebase and git pull --merge to integrate remote changes before pushing.

3 Branching and Merging

2 topics

Branch Operations

Create, list, switch (git switch/checkout), rename, and delete branches, explaining that branches are lightweight pointers to commits and that HEAD tracks the current branch.
Merge branches using git merge, distinguishing between fast-forward merges (linear history) and three-way merges (merge commits), and explain when Git performs each type automatically.
Detect, understand, and resolve merge conflicts by editing conflict markers (<<<< ==== >>>>), staging resolved files, and completing the merge commit, using git merge --abort to abandon a conflicted merge.

Rebasing

Rebase a feature branch onto an updated target branch using git rebase, explaining how rebase replays commits to create a linear history and the golden rule of never rebasing published/shared commits.
Use interactive rebase (git rebase -i) to squash, reword, reorder, edit, and drop commits in a branch's history, cleaning up work-in-progress commits before merging to the main branch.
Evaluate the tradeoffs between merge-based and rebase-based integration strategies, choosing the appropriate approach based on team conventions, history readability, and bisectability requirements.

4 Advanced Operations and Recovery

2 topics

Stash, Cherry-Pick, and Tags

Use git stash to temporarily save uncommitted changes (push, pop, list, apply, drop), switching contexts without committing work-in-progress, and apply stashes selectively.
Apply specific commits from one branch to another using git cherry-pick, and revert commits non-destructively using git revert (creating a new commit that undoes the changes).
Create and manage lightweight and annotated tags for release marking, push tags to remotes, and follow semantic versioning conventions (MAJOR.MINOR.PATCH) for tag naming.

Reset, Reflog, and Recovery

Explain the three modes of git reset (--soft, --mixed, --hard) and their effects on HEAD, the staging area, and the working directory, choosing the appropriate mode for undoing commits vs unstaging files.
Use git reflog to find lost commits after reset, rebase, or other history-rewriting operations, and recover orphaned commits by creating a new branch at the reflog entry.

5 Workflows and Collaboration

1 topic

Branching Workflows

Describe and compare common Git workflows: feature branch workflow, GitFlow (main, develop, feature, release, hotfix branches), trunk-based development, and forking workflow, identifying the tradeoffs in complexity, release cadence, and team size suitability.
Execute the pull request workflow: create a feature branch, push to remote, open a pull request, participate in code review, address feedback with additional commits, and merge using the team's preferred strategy (merge commit, squash, or rebase).
Evaluate merge strategies for pull requests (merge commit preserves full history, squash merge creates a single clean commit, rebase merge maintains linear history) and choose the appropriate strategy based on project conventions and traceability requirements.

Scope

Included Topics

Git fundamentals: repository initialization (git init), the three-area model (working directory, staging area/index, repository), git add, git commit, git status, git log, git diff, and the concept of snapshots vs diffs.
Remote operations: git clone, git remote (add, remove, show), git push, git pull, git fetch, upstream tracking branches, and the relationship between local and remote branches (origin/main).
Branching and merging: git branch (create, list, delete), git checkout/switch, git merge (fast-forward and three-way), merge conflicts (detection, resolution, tools), and git log --graph for visualizing branch history.
Rebasing: git rebase (onto a branch, interactive rebase for squashing, rewording, reordering), the golden rule of rebasing (never rebase published commits), and comparing rebase vs merge workflows.
Advanced operations: git stash (push, pop, list, apply, drop), git cherry-pick, git revert (vs reset), git reset (--soft, --mixed, --hard), git reflog for recovery, git bisect for bug hunting, and git blame for line-level history.
History and inspection: git log options (--oneline, --graph, --all, --author, --since, --grep), git show, git diff (staged, unstaged, between commits/branches), and gitk/git log visualization.
Git workflows: feature branch workflow, GitFlow (main, develop, feature, release, hotfix branches), trunk-based development, forking workflow, and pull request / merge request conventions.
Configuration and ignore: .gitignore patterns, global gitignore, git config (user.name, user.email, core.editor, merge.tool), SSH key setup, and credential management.
Tags: lightweight tags vs annotated tags, git tag (create, list, delete, push), semantic versioning conventions, and using tags for release management.
Collaboration patterns: pull requests, code review workflows, protected branches, merge strategies (merge commit, squash merge, rebase merge), and resolving conflicts in collaborative settings.

Not Covered

Git hosting platform features (GitHub Actions, GitLab CI/CD, Bitbucket Pipelines) beyond basic pull request and code review concepts.
Git LFS (Large File Storage) and managing binary assets in repositories.
Git submodules and subtrees beyond basic awareness.
Custom git hooks scripting and server-side hook administration.
Enterprise Git server administration, access control, and repository management.
