Multiple working directories from one repository
git worktree allows multiple branches to be checked out in separate directories while sharing the same repository object database. This is useful when you need to inspect one branch while keeping another branch's working directory untouched.
Useful development scenario
You might keep a feature branch open in your editor while creating another worktree for a release branch or urgent production fix. This avoids repeatedly stashing and switching a large working tree.
Manage worktrees explicitly
List existing worktrees and remove them when they are no longer needed. A branch normally cannot be checked out simultaneously in two worktrees.
