SYNOPSIS
--------
[verse]
+'git worktree add' [-f] [--detach] [-b <new-branch>] <path> [<branch>]
'git worktree prune' [-n] [-v] [--expire <expire>]
DESCRIPTION
-----------
-Manage multiple worktrees attached to the same repository. These are
-created by the command `git checkout --to`.
+Manage multiple worktrees 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 checkout --to` a new working
+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
(e.g. `git status`) in order to update its administrative files in the
repository so that they do not get automatically pruned.
-To prevent a $GIT_DIR/worktrees entry from from being pruned (which
-can be useful in some situations, such as when the
-entry's working tree is stored on a portable device), add 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.
+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 creating a file named 'lock' alongside the other
+administrative files, optionally containing a plain text reason that
+pruning should be suppressed. See section "DETAILS" for more information.
COMMANDS
--------
+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.
++
+If `<branch>` is omitted and neither `-b` nor `-B` is used, then, as a
+convenience, a new branch based at HEAD is created automatically, as if
+`-b $(basename <path>)` was specified.
+
prune::
Prune working tree information in $GIT_DIR/worktrees.
OPTIONS
-------
+-f::
+--force::
+ By default, `add` refuses to create a new worktree when `<branch>`
+ is already checked out by another worktree. 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 worktree.
+ 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>`.
+
+--detach::
+ With `add`, detach HEAD in the new worktree. See "DETACHED HEAD" in
+ linkgit:git-checkout[1].
+
-n::
--dry-run::
With `prune`, do not remove anything; just report what it would
$GIT_DIR/worktrees directory. The private sub-directory's name is usually
the base name of the linked working tree's path, possibly appended with a
number to make it unique. For example, when `$GIT_DIR=/path/main/.git` the
-command `git checkout --to /path/other/test-next next` creates the linked
+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).
$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.
+To prevent a $GIT_DIR/worktrees entry from from being pruned (which
+can be useful in some situations, such as when the
+entry's working tree is stored on a portable device), add a file named
+'locked' to the entry's directory. The file contains the reason in
+plain text. For example, if a linked working tree's `.git` file points
+to `/path/main/.git/worktrees/test-next` then a file named
+`/path/main/.git/worktrees/test-next/locked` will prevent the
+`test-next` entry from being pruned. See
+linkgit:gitrepository-layout[5] for details.
+
+EXAMPLES
+--------
+You are in the middle of a refactoring session and your boss comes in and
+demands that you fix something immediately. You might typically use
+linkgit:git-stash[1] to store your changes away temporarily, however, your
+worktree is in such a state of disarray (with new, moved, and removed files,
+and other bits and pieces strewn around) that you don't want to risk
+disturbing any of it. Instead, you create a temporary linked worktree to
+make the emergency fix, remove it when done, and then resume your earlier
+refactoring session.
+
+------------
+$ 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 support for submodules is incomplete. It is NOT
-recommended to make multiple checkouts of a superproject.
+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 or via other commands, such as:
+performed manually, such as:
-- `add` to create a new linked worktree
- `remove` to remove a linked worktree and its administrative files (and
warn if the worktree is dirty)
- `mv` to move or rename a worktree and update its administrative files
- `lock` to prevent automatic pruning of administrative files (for instance,
for a worktree on a portable device)
