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
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.pruneworktreesexpire` 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 directory to another file system, or
+within a file system that does not support hard links, you need to run
+at least one git command inside the linked working directory
+(e.g. `git status`) in order to update its administrative files in the
+repository so that they do not get automatically pruned.
+
+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.
+
+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.
+ 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
+ remove.
+
+-v::
+--verbose::
+ With `prune`, report all removals.
+
+--expire <time>::
+ With `prune`, only expire unused worktrees older than <time>.
+
+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
$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.
-When you are done with a linked working tree you can simply delete it.
-The working tree's entry in the repository's $GIT_DIR/worktrees
-directory will eventually be removed automatically (see
-`gc.pruneworktreesexpire` 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 entries in $GIT_DIR/worktrees.
-
-If you move a linked working directory to another file system, or
-within a file system that does not support hard links, you need to run
-at least one git command inside the linked working directory
-(e.g. `git status`) in order to update its entry in $GIT_DIR/worktrees
-so that it does not get automatically removed.
-
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
`test-next` entry from being pruned. See
linkgit:gitrepository-layout[5] for details.

+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
----
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)
