Git is a decentralized version management software. With this cheatsheet, you will have quick access to the most common git commands.
Git is a distributed version control system for tracking changes in source code allowing developers to collaborate and maintain project history.
git fetch downloads remote changes but does not merge them. git pull equals git fetch plus git merge.
git merge creates a merge commit preserving full history. git rebase replays commits for a linear history but rewrites hashes. Use merge for team collaboration; use rebase to clean local feature branches. Never rebase already-pushed shared commits.
Common mistakes: committing directly to main/master (use branches instead); unclear commit messages (e.g., 'fix' or 'update'); committing passwords or API keys to the repo; pushing force to shared branches, destroying others' history; not resolving conflicts properly before merging. Recommendations: follow Conventional Commits, use .gitignore and pre-commit hooks for automated checks, and enable branch protection rules.
