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 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 `$GIT_DIR=/path/main/.git` the +command `git worktree add /path/other/test-next next` creates the linked +working tree in `/path/other/test-next` and also creates a +`$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. + +To prevent a $GIT_DIR/worktrees entry 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. See +linkgit:gitrepository-layout[5] for details. + +LIST OUTPUT FORMAT +------------------ +The worktree list command has two output formats. The default format shows the +details on a single line with columns. For example: + +------------ +S git worktree list +/path/to/bare-source (bare) +/path/to/linked-worktree abcd1234 [master] +/path/to/other-linked-worktree 1234abc (detached HEAD) +------------ + +Porcelain Format +~~~~~~~~~~~~~~~~ +The porcelain format has a line per attribute. Attributes are listed with a +label and value separated by a single space. Boolean attributes (like 'bare' +and 'detached') are listed as a label only, and are only present if and only +if the value is true. An empty line indicates the end of a worktree. For +example: + +------------ +S git worktree list --porcelain +worktree /path/to/bare-source +bare + +worktree /path/to/linked-worktree +HEAD abcd1234abcd1234abcd1234abcd1234abcd1234 +branch refs/heads/master + +worktree /path/to/other-linked-worktree +HEAD 1234abc1234abc1234abc1234abc1234abc1234a +detached + +------------ + +EXAMPLES +-------- +You are in the middle of a refactoring session and your boss comes in and +demands that you fix something immediately.

Instead, we generally prefer these strategies: + + - bumping format version numbers of individual data files (e.g., + index, packfiles, etc). This restricts the incompatibilities only to + those files. + + - introducing new data that gracefully degrades when used by older + clients (e.g., pack bitmap files are ignored by older clients, which + simply do not take advantage of the optimization they provide). + +A whole-repository format version bump should only be part of a change +that cannot be independently versioned. For instance, if one were to +change the reachability rules for objects, or the rules for locking +refs, that would require a bump of the repository format version. + +Note that this applies only to accessing the repository's disk contents +directly. An older client which understands only format `0` may still +connect via `git://` to a repository using format `1`, as long as the +server process understands format `1`. + +The preferred strategy for rolling out a version bump (whether whole +repository or for a single file) is to teach git to read the new format, +and allow writing the new format with a config switch or command line +option (for experimentation or for those who do not care about backwards +compatibility with older gits).
