With `git checkout --to` a new working +tree is associated with the repository. This new working tree is called a +"linked working tree" as opposed to the "main working tree" prepared by "git +init" or "git clone". A repository has one main working tree (if it's not a +bare repository) and zero or more linked working trees. + +Each linked working tree has a private sub-directory in the repository's +$GIT_DIR/worktrees directory. The private sub-directory's name is usually +the base name of the linked working tree's path, possibly appended with a +number to make it unique. For example, when `$GIT_DIR=/path/main/.git` the +command `git checkout --to /path/other/test-next next` creates the linked +working tree in `/path/other/test-next` and also creates a +`$GIT_DIR/worktrees/test-next` directory (or `$GIT_DIR/worktrees/test-next1` +if `test-next` is already taken). + +Within a linked working tree, $GIT_DIR is set to point to this private +directory (e.g. `/path/main/.git/worktrees/test-next` in the example) and +$GIT_COMMON_DIR is set to point back to the main working tree's $GIT_DIR +(e.g. `/path/main/.git`). These settings are made in a `.git` file located at +the top directory of the linked working tree. + +Path resolution via `git rev-parse --git-path` uses either +$GIT_DIR or $GIT_COMMON_DIR depending on the path. For example, in the +linked working tree `git rev-parse --git-path HEAD` returns +`/path/main/.git/worktrees/test-next/HEAD` (not +`/path/other/test-next/.git/HEAD` or `/path/main/.git/HEAD`) while `git +rev-parse --git-path refs/heads/master` uses +$GIT_COMMON_DIR and returns `/path/main/.git/refs/heads/master`, +since refs are shared across all working trees. + +See linkgit:gitrepository-layout[5] for more information. The rule of +thumb is do not make any assumption about whether a path belongs to +$GIT_DIR or $GIT_COMMON_DIR when you need to directly access something +inside $GIT_DIR. Use `git rev-parse --git-path` to get the final path. + +When you are done with a linked working tree you can simply delete it. +The working tree's entry in the repository's $GIT_DIR/worktrees +directory will eventually be removed automatically (see +`gc.pruneworktreesexpire` in linkgit::git-config[1]), or you can run +`git prune --worktrees` in the main or any linked working tree to +clean up any stale entries in $GIT_DIR/worktrees. + +If you move a linked working directory to another file system, or +within a file system that does not support hard links, you need to run +at least one git command inside the linked working directory +(e.g. `git status`) in order to update its entry in $GIT_DIR/worktrees +so that it does not get automatically removed. + +To prevent a $GIT_DIR/worktrees entry from from being pruned (which +can be useful in some situations, such as when the +entry's working tree is stored on a portable device), add a file named +'locked' to the entry's directory. The file contains the reason in +plain text. For example, if a linked working tree's `.git` file points +to `/path/main/.git/worktrees/test-next` then a file named +`/path/main/.git/worktrees/test-next/locked` will prevent the +`test-next` entry from being pruned.
