# Worktree kit Use the manager script for all worktree actions. ```bash bash "${CODEX_HOME:-$HOME/.codex}/scripts/worktree.sh" <command> [args] ``` Commands: - `create <name> [base]` - `list` - `switch <name>` (prints the worktree path; it cannot change your shell's directory - use `cd "$(... switch <name>)"`) - `cleanup [<name>...] [--yes]` (no args = interactive; names skip the prompt; `--yes` skips the confirmation, required off a terminal) - `copy-env <name>` Safety notes: - `create` does not change the current branch - `create` sets no upstream on the new branch (`--no-track`) - under the upstream-based push modes (`simple`, `upstream`, `current`) a bare `git push` cannot aim at the base branch; under the default `push.default=simple` (without `push.autoSetupRemote`) the first push needs `git push -u origin <name>` (legacy `push.default=matching` pushes all name-matched branches regardless of upstream) - `cleanup` does not force-remove worktrees and does not delete branches - `cleanup` deletes the worktree directory (including ignored files); removal fails if the worktree is not clean - `.env*` is copied with no overwrite (symlinks skipped) - refuses to operate if `.worktrees/` or any worktree path component is a symlink - `copy-env` only targets registered worktrees - `origin` fetch is optional; local base refs are allowed - fetch from `origin` only when base looks like a branch - Worktrees live under `.worktrees/` - `create` initializes `.worktrees/.gitignore` (`*`...
