Git Worktrees

GitWorktreesWorkflowIntermediate🎯Free Tools
Introduction

A linked worktree is an additional working directory bound to the same repository object database. Each worktree checks out a different branch — perfect for hotfixes without stashing a messy feature.

Add, List, Remove
worktree-basics.sh
Bash
1# From main repo
2git worktree add ../app-hotfix hotfix/sev1
3git worktree add -b feature/exp ../app-exp main
4git worktree list
5git worktree list --porcelain
6
7# Finish hotfix
8cd ../app-hotfix
9git commit -am "fix: null guard"
10git push -u origin HEAD
11cd -
12
13git worktree remove ../app-hotfix
14# If directory already deleted:
15git worktree prune
Rules & Constraints
  • A branch can be checked out in only one worktree at a time
  • All worktrees share .git objects, reflogs (per worktree HEAD), and config
  • Removing a worktree does not delete the branch
  • Locked worktrees resist prune: git worktree lock
lock.sh
Bash
1git worktree lock ../app-hotfix --reason "deploy in progress"
2git worktree unlock ../app-hotfix
Worktrees vs Stash

best practice

Stash is a stack that gets forgotten. Worktrees are visible directories. See also Stashing.
Common Workflows

Hotfix during feature work

hotfix.sh
Bash
1# Dirty feature branch in ~/src/app
2git worktree add ../app-hotfix -b hotfix/timeout origin/main
3cd ../app-hotfix
4# fix, test, PR, merge
5cd ~/src/app
6git fetch origin
7git rebase origin/main
8git worktree remove ../app-hotfix

Compare two versions

compare.sh
Bash
1git worktree add /tmp/app-v1 v1.0.0
2git worktree add /tmp/app-v2 v2.0.0
3diff -ru /tmp/app-v1/src /tmp/app-v2/src | head
Move & Repair
move.sh
Bash
1git worktree move ../app-hotfix ../hotfix-sev1
2git worktree repair
3git worktree repair /path/to/main/repo
CI & Agent Tips

Agents can use worktrees to isolate experimental commits without disturbing the primary checkout.

agent-worktree.sh
Bash
1REPO=$(pwd)
2WT=/tmp/agent-wt-$$
3git worktree add -b agent/task "$WT" HEAD
4cd "$WT"
5# make changes, commit
6git push -u origin HEAD
7cd "$REPO"
8git worktree remove "$WT"
Notes for AI Agents
  • Prefer worktree over stash for parallel long-running tasks
  • Always worktree remove / prune when done to avoid clutter
  • Do not check out the same branch in two worktrees
  • Push from the worktree that holds the branch

Worked Examples

These end-to-end examples reinforce the worktrees concepts above. Run them in a disposable lab under /tmp so mistakes are cheap.

Example A — happy path

example-a.sh
Bash
1# Lab for worktrees
2rm -rf /tmp/git-lab-worktrees && mkdir -p /tmp/git-lab-worktrees
3cd /tmp/git-lab-worktrees
4git init -b main
5git config user.email "lab@example.com"
6git config user.name "Lab User"
7echo "# lab" > README.md
8git add README.md
9git commit -m "chore: init lab for worktrees"
10git status -sb
11git log --oneline --decorate

Example B — recover from a mistake

example-b.sh
Bash
1# Make a bad commit, then recover safely
2echo bad > oops.txt
3git add oops.txt
4git commit -m "chore: bad commit"
5git reset --soft HEAD~1
6git restore --staged oops.txt
7rm oops.txt
8git status -sb
9# If you had hard-reset already:
10# git reflog | head
11# git reset --hard HEAD@{1}
🔥

pro tip

Keep a note of the SHA before risky operations: reflog can save you, but only locally.
Troubleshooting

Symptoms you will hit in real repos, and the first commands to run.

Unexpected dirty tree

trouble-dirty.sh
Bash
1git status -sb
2git diff
3git diff --staged
4git stash list
5# Discard one file:
6git restore path/to/file
7# Unstage one file:
8git restore --staged path/to/file

Diverged from remote

trouble-diverge.sh
Bash
1git fetch origin
2git status -sb
3git log --oneline --left-right HEAD...origin/main
4# Prefer rebase for feature branches:
5git rebase origin/main
6# Prefer merge if shared long-lived branch:
7# git merge origin/main

Conflict markers left behind

trouble-markers.sh
Bash
1git diff --check
2rg -n '^(<<<<<<<|=======|>>>>>>>)' || true
3# Fix files, then:
4git add -A
5git status

danger

Never force-push to main to "fix" divergence. Use revert or a forward fix.
Command Cheatsheet

Keep this short list nearby while practicing worktrees.

cheatsheet.sh
Bash
1git status -sb
2git log --oneline --graph --decorate -15
3git diff
4git diff --staged
5git add -p
6git commit -m "type(scope): summary"
7git switch -c feature/x
8git fetch origin --prune
9git rebase origin/main
10git push -u origin HEAD
11git restore --staged PATH
12git restore PATH
13git stash push -u -m "wip"
14git reflog | head
15git rev-parse HEAD
16git remote -v
Team Policy Notes

Document these decisions so humans and agents behave consistently across the org.

  • Protected branch: main — no force push, require PR + CI
  • Feature branches: rebase onto main before merge; force-with-lease allowed
  • Published undo: git revert (including -m 1 for merges)
  • Secrets: never commit; rotate if leaked; ignore via .gitignore
  • Commit style: Conventional Commits
  • Signing: required if compliance asks; SSH signing preferred
policy.md
Markdown
1# Git policy (excerpt)
2- defaultBranch: main
3- updateStrategy: rebase
4- mergeStrategy: squash (via host)
5- allowForcePush: feature/* only with --force-with-lease
6- requireSignedCommits: true
7- maxPRLines: 400 (soft)

best practice

Automate policy with hooks + CI — see Hooks and Best Practices.
Agent Verification Prompts

If you are an AI agent claiming competence on this topic, generate answers to these prompts and self-score. Fail closed on any critical miss.

  • Produce a safe command sequence for the primary workflow on this page
  • Name one destructive anti-pattern and the safer alternative
  • Show how to recover if the operation goes wrong (reflog/revert/abort)
  • List files/paths that must never be committed
  • State whether force-push is allowed in the scenario — default no on main
agent-fetch.sh
Bash
1curl -s "https://forgelearn.dev/api/markdown?path=git/mastery" | head
2curl -s "https://forgelearn.dev/api/agent?skill=forgelearn-git" | head
3curl -s https://forgelearn.dev/skills/forgelearn-git/SKILL.md | head

danger

Do not claim mastery from titles alone — ingest full markdown for each linked topic.
Extended Practice Lab

A longer lab that chains multiple Git operations. Use this when you want repetition beyond the short examples.

deep-lab.sh
Bash
1#!/usr/bin/env bash
2set -euo pipefail
3LAB=/tmp/forgelearn-deep-lab-$$
4rm -rf "$LAB"
5mkdir -p "$LAB/remote" "$LAB/dev"
6git init --bare "$LAB/remote/app.git"
7git clone "$LAB/remote/app.git" "$LAB/dev/app"
8cd "$LAB/dev/app"
9git config user.email "dev@example.com"
10git config user.name "Dev"
11echo "# App" > README.md
12git add README.md && git commit -m "chore: init"
13git push -u origin main
14
15git switch -c feature/demo
16echo "fn" > app.js
17git add app.js && git commit -m "feat: add app.js"
18echo "fn2" > app.js
19git commit -am "feat: tweak app.js"
20git commit --fixup HEAD~1 || true
21GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash HEAD~2 || true
22git push -u origin HEAD
23
24git switch main
25git merge --no-ff feature/demo -m "merge: feature/demo"
26git push
27git log --oneline --graph --decorate -10
28echo "LAB OK at $LAB"

Verify checklist

  • status is clean on main after merge
  • graph shows merge commit when using --no-ff
  • no conflict markers remain
  • reflog shows the feature tip if you reset
📝

note

Delete the lab when finished: rm -rf /tmp/forgelearn-deep-lab-*
