Creating a worktree in Git - Quick Revision & Summary

Recall & Review

beginner

What is a Git worktree?

A Git worktree is an additional working directory linked to the same Git repository. It allows you to work on multiple branches simultaneously without switching branches in a single directory.

beginner

How do you create a new worktree for a branch named feature?

Use the command git worktree add <path> feature. This creates a new directory at <path> with the feature branch checked out.

Why use Git worktrees instead of cloning the repository multiple times?

Worktrees share the same Git repository data, saving disk space and keeping history consistent. Cloning multiple times duplicates data and uses more space.

beginner

What command lists all existing Git worktrees?

Run git worktree list to see all worktrees linked to the repository, including their paths and checked-out branches.

intermediate

How do you remove a Git worktree safely?

First, delete the worktree directory manually. Then run git worktree prune to clean up references to removed worktrees.

What does the command git worktree add ./new-feature feature do?

A Creates a new directory ./new-feature with the branch 'feature' checked out

B Deletes the branch 'feature'

C Switches the current directory to branch 'feature'

D Clones the repository into ./new-feature

The command adds a new worktree at ./new-feature with the 'feature' branch checked out.

Which command shows all worktrees linked to your Git repository?

A git status

B git branch -a

C git remote -v

D git worktree list

git worktree list displays all worktrees connected to the repository.

Why might you prefer a Git worktree over cloning the repo multiple times?

A Worktrees save disk space by sharing repository data

B Worktrees create separate repositories

C Cloning is faster than worktrees

D Worktrees do not support multiple branches

Worktrees share the same Git data, saving disk space compared to multiple clones.

What must you do after deleting a worktree directory manually?

A Run <code>git branch -d</code>

B Run <code>git clone</code>

C Run <code>git worktree prune</code> to clean references

D Nothing, Git cleans automatically

After manual deletion, git worktree prune removes stale references.

Can you have multiple worktrees checked out on different branches at the same time?

A No, only one worktree can be active

B Yes, that is the main benefit of worktrees

C Yes, but only if branches are merged

D No, worktrees share the same branch

Worktrees let you work on multiple branches simultaneously in separate directories.

Explain what a Git worktree is and why it is useful.

Think about working on two projects at once without switching folders.

Describe the steps to create and then remove a Git worktree safely.

Consider how to add a new folder for a branch and clean up after.
