5 Git Tricks That Make You Look Like a Senior Dev

Most developers use about 20% of Git's power. These 5 commands are the other 80%. Master them and you'll solve problems in seconds that others spend hours on.

Interactive Rebase - Clean Commit History

Never push a messy branch again. Interactive rebase lets you squash, reorder, and edit commits before anyone sees them.

git rebase -i HEAD~4

This opens an editor with your last 4 commits. Change pick to squash to combine commits, or reword to fix a message. Your PR reviewer will thank you.

Git Bisect - Find the Bug in O(log n)

A bug was introduced sometime in the last 100 commits. Instead of checking them one by one, let Git binary-search for you:

git bisect start
git bisect bad HEAD   # current state is broken
git bisect good v1.0.0   # last known good state

Git checks out a commit in the middle. Test it, mark it git bisect good or git bisect bad. In 7 steps, you'll find the exact commit among 100. Then git bisect reset to return.

Worktrees - Work on Two Branches Simultaneously

Need to switch branches but don't want to stash your changes? Worktrees let you check out multiple branches into separate directories - all from one repo.

git worktree add ../feature-branch feature-branch

Now you have two working directories: your current one and ../feature-branch. Make changes in either, they share the same .git folder. Perfect for hotfixes while deep in a feature.

Reflog - Your Undo Safety Net

Accidentally deleted a branch? Force-pushed the wrong thing? git reflog shows every action Git has taken in the last 90 days:

git reflog
# abc1234 HEAD@{0}: commit: fix login bug
# def5678 HEAD@{1}: reset: moving to HEAD~3
# ghi9012 HEAD@{2}: commit: add payment feature

Find the commit you lost and do git checkout ghi9012 to recover it. The reflog has saved more careers than any StackOverflow answer.

Partial Staging - Commit Specific Lines

You made 5 changes in one file but only want to commit 2 of them. Don't copy-paste into a new file. Use interactive staging:

git add -p

Git shows each chunk and asks what to do. Press y to stage it, n to skip, or s to split a large chunk into smaller ones. Commit exactly what you mean to commit.

Bottom Line

Start with git add -p and git reflog - you'll use those weekly. Then add rebase -i for your next PR. Bisect and worktrees are your secret weapons for the tough debugging sessions. Senior developers don't memorize more commands. They know fewer commands that solve problems faster.
