Worktree¶
A worktree is a Git feature that allows multiple working directories to be linked to a single repository. With git worktree add, a developer can check out a different branch into a separate directory without disturbing the current working directory.
This is useful when:
Working on a hotfix while keeping the main feature branch open
Running tests or builds on a different branch simultaneously
Comparing the current implementation against another branch side by side
CI/CD pipelines needing isolated checkouts from the same repository
Each linked worktree has its own index and HEAD but shares the object store with the main repository, avoiding duplication.
