NAME         top

       git-worktree - Manage multiple working trees

SYNOPSIS         top

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

DESCRIPTION         top

       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 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

COMMANDS         top

       add <path> [<branch>]
           Create <path> and checkout <branch> 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 <branch>; it is synonymous with @{-1}.

           If <branch> 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 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

           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 working tree information in $GIT_DIR/worktrees.

           Unlock a working tree, allowing it to be pruned, moved or

OPTIONS         top

       -f, --force
           By default, add refuses to create a new working tree when
           <branch> 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
           <branch>, and check out <new-branch> into the new working tree.
           If <branch> 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 <branch>.

           With add, detach HEAD in the new working tree. See "DETACHED
           HEAD" in git-checkout(1).

           By default, add checks out <branch>, however, --no-checkout can
           be used to suppress checkout in order to make customizations,
           such as configuring sparse-checkout. See "Sparse checkout" in

           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

           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.

           Working trees can be identified by path, either relative or

           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         top

       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

       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 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 gitrepository-layout(5)
       for details.


       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

           worktree /path/to/linked-worktree
           HEAD abcd1234abcd1234abcd1234abcd1234abcd1234
           branch refs/heads/master

           worktree /path/to/other-linked-worktree
           HEAD 1234abc1234abc1234abc1234abc1234abc1234a

EXAMPLES         top

       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 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         top

       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
