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, remove it with `git worktree remove`.
|
|
|
|
If a working tree is deleted without using `git worktree remove`, then
|
|
its associated administrative files, which reside 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
|
|
or linked working trees containing submodules cannot be moved.
|
|
|
|
prune::
|
|
|
|
Prune working tree information in $GIT_DIR/worktrees.
|
|
|
|
remove::
|
|
|
|
Remove a working tree. Only clean working trees (no untracked files
|
|
and no modification in tracked files) can be removed. Unclean working
|
|
trees or ones with submodules can be removed with `--force`. The main
|
|
working tree cannot be removed.
|
|
|
|
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 and `remove` refuses to remove an unclean
|
|
working tree. This option overrides these safeguards.
|
|
|
|
-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:
|
|
|
|
------------
|
|
$ 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:
|
|
|
|
------------
|
|
$ 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
|
|
$ git worktree remove ../temp
|
|
------------
|
|
|
|
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.
