DESCRIPTION
-----------
Verifies the connectivity and validity of the objects in the database.

OPTIONS
-------
<object>::
	An object to treat as the head of an unreachability trace.
+
If no objects are given, 'git fsck' defaults to using the
index file, all SHA-1 references in the `refs` namespace, and all reflogs
(unless --no-reflogs is given) as heads.

--unreachable::
	Print out objects that exist but that aren't reachable from any
	of the reference nodes.

--[no-]dangling::
	Print objects that exist but that are never 'directly' used (default).
	`--no-dangling` can be used to omit this information from the output.

--root::
	Report root nodes.

--tags::
	Report tags.

--cache::
	Consider any object recorded in the index also as a head node for
	an unreachability trace.

--no-reflogs::
	Do not consider commits that are referenced only by an
	entry in a reflog to be reachable.  This option is meant
	only to search for commits that used to be in a ref, but
	now aren't, but are still in that corresponding reflog.

--full::
	Check not just objects in GIT_OBJECT_DIRECTORY
	($GIT_DIR/objects), but also the ones found in alternate
	object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES
	or $GIT_DIR/objects/info/alternates,
	and in packed Git archives found in $GIT_DIR/objects/pack
	and corresponding pack subdirectories in alternate
	object pools.  This is now default; you can turn it off
	with --no-full.

--connectivity-only::
	Check only the connectivity of reachable objects, making sure
	that any objects referenced by a reachable tag, commit, or tree
	are present. This speeds up the operation by avoiding reading
	blobs entirely (though it does still check that referenced blobs
	exist). This will detect corruption in commits and trees, but
	not do any semantic checks (e.g., for format errors). Corruption
	in blob objects will not be detected at all.
+
Unreachable tags, commits, and trees will also be accessed to find the
tips of dangling segments of history. Use `--no-dangling` if you don't
care about this output and want to speed it up further.

--strict::
	Enable more strict checking, namely to catch a file mode
	recorded with g+w bit set, which was created by older
	versions of Git.  Existing repositories, including the
	Linux kernel, Git itself, and sparse repository have old
	objects that trigger this check, but it is recommended
	to check new projects with this flag.

--verbose::
	Be chatty.

--lost-found::
	Write dangling objects into .git/lost-found/commit/ or
	.git/lost-found/other/, depending on type.  If the object is
	a blob, the contents are written into the file, rather than
	its object name.

--name-objects::
