NAME
----
git-worktree - Manage multiple working trees


SYNOPSIS
--------
[verse]
'git worktree add' [-f] [--detach] [--checkout] [--lock] [-b <new-branch>] <path> [<commit-ish>]
'git worktree list' [--porcelain]
'git worktree lock' [--reason <string>] <worktree>
'git worktree prune' [-n] [-v] [--expire <expire>]
'git worktree unlock' <worktree>

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 you move a linked working tree, you need to manually update the
administrative files so that they do not get pruned automatically. See
section "DETAILS" for more information.

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 worktree with a branch named after
`$(basename <path>)` (call it `<branch>`) is created.  If `<branch>`
doesn't exist, a new branch based on HEAD is automatically created as
if `-b <branch>` was given.  If `<branch>` exists in the repository,
it will be checked out in the new worktree, if it's not checked out
anywhere else, otherwise the command will refuse to create the
worktree (unless `--force` is used).

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`.

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 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)
- `mv` to move or rename a working tree and update its administrative files
