Essential Git Commands: The Developer's Cheat Sheet

Git Fundamentals

Git is a distributed version control system created by Linus Torvalds in 2005. Understanding its core concepts — commits, branches, remotes, and the staging area — is essential for every developer regardless of the languages they use.

Essential Daily Commands

• git status — See what has changed
• git add -p — Stage changes interactively, chunk by chunk
• git commit -m "message" — Commit staged changes
• git log --oneline --graph — Visual branch history
• git diff HEAD — See all uncommitted changes

Branching and Merging

Use git checkout -b feature/name to create and switch to a new branch. Use git merge --no-ff feature/name to merge with a merge commit, preserving history. git rebase creates a linear history by replaying commits on top of the target branch.

Recovery Commands

Made a mistake? git reset --soft HEAD~1 undoes the last commit but keeps changes staged. git stash temporarily shelves changes. git reflog shows a history of all HEAD movements and can recover seemingly lost commits.

Useful Aliases

Set git config --global alias.st status to shorten common commands. Aliases save significant time in workflows with frequent git operations.
