This command allows to relocate linked worktrees. Main worktree cannot (yet) be moved. There are two options to move the main worktree, but both have complications, so it's not implemented yet. Anyway the options are: - convert the main worktree to a linked one and move it away, leave the git repository where it is. The repo essentially becomes bare after this move. - move the repository with the main worktree. The tricky part is make sure all file descriptors to the repository are closed, or it may fail on Windows.

DESCRIPTION
|
|
-----------
|
|
|
|
Manage multiple working trees attached to the same repository.
|
|
|
|
A git repository can support multiple working trees, allowing you to check
|
|
out more than one branch at a time. With `git worktree add` 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.
|
|
|
|
When you are done with a linked working tree you can simply delete it.
|
|
The working tree's administrative files in the repository (see
|
|
"DETAILS" below) will eventually be removed automatically (see
|
|
`gc.worktreePruneExpire` in linkgit:git-config[1]), or you can run
|
|
`git worktree prune` in the main or any linked working tree to
|
|
clean up any stale administrative files.
|
|
|
|
If a linked working tree is stored on a portable device or network share
|
|
which is not always mounted, you can prevent its administrative files from
|
|
being pruned by issuing the `git worktree lock` command, optionally
|
|
specifying `--reason` to explain why the working tree is locked.
|
|
|
|
COMMANDS
|
|
--------
|
|
add <path> [<commit-ish>]::
|
|
|
|
Create `<path>` and checkout `<commit-ish>` into it. The new working directory
|
|
is linked to the current repository, sharing everything except working
|
|
directory specific files such as HEAD, index, etc. `-` may also be
|
|
specified as `<commit-ish>`; it is synonymous with `@{-1}`.
|
|
+
|
|
If <commit-ish> is a branch name (call it `<branch>` and is not found,
|
|
and neither `-b` nor `-B` nor `--detach` are used, but there does
|
|
exist a tracking branch in exactly one remote (call it `<remote>`)
|
|
with a matching name, treat as equivalent to
|
|
------------
|
|
$ git worktree add --track -b <branch> <path> <remote>/<branch>
|
|
------------
|
|
+
|
|
If `<commit-ish>` is omitted and neither `-b` nor `-B` nor `--detach` used,
|
|
then, as a convenience, a new branch based at HEAD is created automatically,
|
|
as if `-b $(basename <path>)` was specified.
|
|
|
|
list::
|
|
|
|
List details of each worktree. The main worktree is listed first, followed by
|
|
each of the linked worktrees. The output details include if the worktree is
|
|
bare, the revision currently checked out, and the branch currently checked out
|
|
(or 'detached HEAD' if none).
|
|
|
|
lock::
|
|
|
|
If a working tree is on a portable device or network share which
|
|
is not always mounted, lock it to prevent its administrative
|
|
files from being pruned automatically. This also prevents it from
|
|
being moved or deleted. Optionally, specify a reason for the lock
|
|
with `--reason`.
|
|
|
|
move::
|
|
|
|
Move a working tree to a new location. Note that the main working tree
|
|
cannot be moved.
|
|
|
|
prune::
|
|
|
|
Prune working tree information in $GIT_DIR/worktrees.
|
|
|
|
unlock::
|
|
|
|
Unlock a working tree, allowing it to be pruned, moved or deleted.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-f::
|
|
--force::
|
|
By default, `add` refuses to create a new working tree when `<commit-ish>` is a branch name and
|
|
is already checked out by another working tree. This option overrides
|
|
that safeguard.
|
|
|
|
-b <new-branch>::
|
|
-B <new-branch>::
|
|
With `add`, create a new branch named `<new-branch>` starting at
|
|
`<commit-ish>`, and check out `<new-branch>` into the new working tree.
|
|
If `<commit-ish>` is omitted, it defaults to HEAD.
|
|
By default, `-b` refuses to create a new branch if it already
|
|
exists. `-B` overrides this safeguard, resetting `<new-branch>` to
|
|
`<commit-ish>`.
|
|
|
|
--detach::
|
|
With `add`, detach HEAD in the new working tree. See "DETACHED HEAD"
|
|
in linkgit:git-checkout[1].
|
|
|
|
--[no-]checkout::
|
|
By default, `add` checks out `<commit-ish>`, however, `--no-checkout` can
|
|
be used to suppress checkout in order to make customizations,
|
|
such as configuring sparse-checkout. See "Sparse checkout"
|
|
in linkgit:git-read-tree[1].
|
|
|
|
--[no-]guess-remote::
|
|
With `worktree add <path>`, without `<commit-ish>`, instead
|
|
of creating a new branch from HEAD, if there exists a tracking
|
|
branch in exactly one remote matching the basename of `<path>`,
|
|
base the new branch on the remote-tracking branch, and mark
|
|
the remote-tracking branch as "upstream" from the new branch.
|
|
+
|
|
This can also be set up as the default behaviour by using the
|
|
`worktree.guessRemote` config option.
|
|
|
|
--[no-]track::
|
|
When creating a new branch, if `<commit-ish>` is a branch,
|
|
mark it as "upstream" from the new branch. This is the
|
|
default if `<commit-ish>` is a remote-tracking branch. See
|
|
"--track" in linkgit:git-branch[1] for details.
|
|
|
|
--lock::
|
|
Keep the working tree locked after creation. This is the
|
|
equivalent of `git worktree lock` after `git worktree add`,
|
|
but without race condition.
|
|
|
|
-n::
|
|
--dry-run::
|
|
With `prune`, do not remove anything; just report what it would
|
|
remove.
|
|
|
|
--porcelain::
|
|
With `list`, output in an easy-to-parse format for scripts.
|
|
This format will remain stable across Git versions and regardless of user
|
|
configuration. See below for details.
|
|
|
|
-v::
|
|
--verbose::
|
|
With `prune`, report all removals.
|
|
|
|
--expire <time>::
|
|
With `prune`, only expire unused working trees older than <time>.
|
|
|
|
--reason <string>::
|
|
With `lock`, an explanation why the working tree is locked.
|
|
|
|
<worktree>::
|
|
Working trees can be identified by path, either relative or
|
|
absolute.
|
|
+
|
|
If the last path components in the working tree's path is unique among
|
|
working trees, it can be used to identify worktrees. For example if
|
|
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.
|
|
|
|
DETAILS
|
|
-------
|
|
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 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.
|
|
|
|
If you manually move a linked working tree, you need to update the 'gitdir' file
|
|
in the entry's directory. For example, if a linked working tree is moved
|
|
to `/newpath/test-next` and its `.git` file points to
|
|
`/path/main/.git/worktrees/test-next`, then update
|
|
`/path/main/.git/worktrees/test-next/gitdir` to reference `/newpath/test-next`
|
|
instead.
|
|
|
|
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), use the
|
|
`git worktree lock` command, which adds 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. You might typically use
|
|
linkgit:git-stash[1] to store your changes away temporarily, however, your
|
|
working tree is in such a state of disarray (with new, moved, and removed
|
|
files, and other bits and pieces strewn around) that you don't want to risk
|
|
disturbing any of it. Instead, you create a temporary linked working tree to
|
|
make the emergency fix, remove it when done, and then resume your earlier
|
|
refactoring session.
|
|
|
|
------------
|
|
$ git worktree add -b emergency-fix ../temp master
|
|
$ pushd ../temp
|
|
# ... hack hack hack ...
|
|
$ git commit -a -m 'emergency fix for boss'
|
|
$ popd
|
|
$ rm -rf ../temp
|
|
$ git worktree prune
|
|

|
BUGS
|
|
----
|
|
Multiple checkout in general is still experimental, and the support
|
|
for submodules is incomplete. It is NOT recommended to make multiple
|
|
checkouts of a superproject.
|
|
|
|
git-worktree could provide more automation for tasks currently
|
|
performed manually, such as:
|
|
|
|
- `remove` to remove a linked working tree and its administrative files (and
|
|
warn if the working tree is dirty)
