you only have two working trees, at "/abc/def/ghi" and "/abc/def/ggg",
then "ghi" or "def/ghi" is enough to point to the former working tree.
+ REFS
+ ----
+ In multiple working trees, some refs may be shared between all working
+ trees, some refs are local. One example is HEAD is different for all
+ working trees. This section is about the sharing rules and how to access
+ refs of one working tree from another.
+
+ In general, all pseudo refs are per working tree and all refs starting
+ with "refs/" are shared. Pseudo refs are ones like HEAD which are
+ directly under GIT_DIR instead of inside GIT_DIR/refs. There are one
+ exception to this: refs inside refs/bisect and refs/worktree is not
+ shared.
+
+ Refs that are per working tree can still be accessed from another
+ working tree via two special paths, main-worktree and worktrees. The
+ former gives access to per-worktree refs of the main working tree,
+ while the latter to all linked working trees.
+
+ For example, main-worktree/HEAD or main-worktree/refs/bisect/good
+ resolve to the same value as the main working tree's HEAD and
+ refs/bisect/good respectively. Similarly, worktrees/foo/HEAD or
+ worktrees/bar/refs/bisect/bad are the same as
+ GIT_COMMON_DIR/worktrees/foo/HEAD and
+ GIT_COMMON_DIR/worktrees/bar/refs/bisect/bad.
+
+ To access refs, it's best not to look inside GIT_DIR directly. Instead
+ use commands such as linkgit:git-rev-parse[1] or linkgit:git-update-ref[1]
+ which will handle refs correctly.
+
+CONFIGURATION FILE
+------------------
+By default, the repository "config" file is shared across all working
+trees. If the config variables `core.bare` or `core.worktree` are
+already present in the config file, they will be applied to the main
+working trees only.
+
+In order to have configuration specific to working trees, you can turn
+on "worktreeConfig" extension, e.g.:
+
+------------
+$ git config extensions.worktreeConfig true
+------------
+
+In this mode, specific configuration stays in the path pointed by `git
+rev-parse --git-path config.worktree`. You can add or update
+configuration in this file with `git config --worktree`. Older Git
+versions will refuse to access repositories with this extension.
+
+Note that in this file, the exception for `core.bare` and `core.worktree`
+is gone. If you have them in $GIT_DIR/config before, you must move
+them to the `config.worktree` of the main working tree. You may also
+take this opportunity to review and move other configuration that you
+do not want to share to all working trees:
+
+ - `core.worktree` and `core.bare` should never be shared
+
+ - `core.sparseCheckout` is recommended per working tree, unless you
+ are sure you always use sparse checkout for all working trees.
+
DETAILS
-------
Each linked working tree has a private sub-directory in the repository's
`/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.
+ since refs are shared across all working trees, except refs/bisect and
+ refs/worktree.
See linkgit:gitrepository-layout[5] for more information. The rule of
thumb is do not make any assumption about whether a path belongs to
`test-next` entry from being pruned. See
linkgit:gitrepository-layout[5] for details.
+When extensions.worktreeConfig is enabled, the config file
+`.git/worktrees/<id>/config.worktree` is read after `.git/config` is.
+
LIST OUTPUT FORMAT
------------------
The worktree list command has two output formats. The default format shows the
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:
+if the value is true. The first attribute of a worktree is always `worktree`,
+an empty line indicates the end of the record. For example:
------------
$ git worktree list --porcelain
References are stored in subdirectories of this
directory. The 'git prune' command knows to preserve
objects reachable from refs found in this directory and
- its subdirectories. This directory is ignored if $GIT_COMMON_DIR
- is set and "$GIT_COMMON_DIR/refs" will be used instead.
+ its subdirectories.
+ This directory is ignored (except refs/bisect and
+ refs/worktree) if $GIT_COMMON_DIR is set and
+ "$GIT_COMMON_DIR/refs" will be used instead.
refs/heads/`name`::
records tip-of-the-tree commit objects of branch `name`
if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/config" will be
used instead.
+config.worktree::
+ Working directory specific configuration file for the main
+ working directory in multiple working directory setup (see
+ linkgit:git-worktree[1]).
+

A slightly deprecated way to store shorthands to be used
to specify a URL to 'git fetch', 'git pull' and 'git push'.
each hook. This directory is ignored if $GIT_COMMON_DIR is set
and "$GIT_COMMON_DIR/hooks" will be used instead.
+ common::
+ When multiple working trees are used, most of files in
+ $GIT_DIR are per-worktree with a few known exceptions. All
+ files under 'common' however will be shared between all
+ working trees.
index::
The current index file for the repository. It is
or manually by `git worktree prune`. The file may contain a string
explaining why the repository is locked.
