SYNOPSIS

-'git-fsck-cache' [--tags] [--root] [--delta-depth] [[--unreachable] [--cache] <object>\*]

DESCRIPTION
-----------
<object>::
An object to treat as the head of an unreachability trace.
+ If no objects are given, git-fsck-cache defaults to using the
+ index file and all SHA1 references in .git/refs/* as heads.
+
--unreachable::
Print out objects that exist but that aren't readable from any
- of the specified head nodes.
+ of the reference nodes.
--root::
Report root nodes.
Consider any object recorded in the cache also as a head node for
an unreachability trace.
---delta-depth::
- Report back the length of the longest delta chain found.
+--standalone::
+ Limit checks to the contents of GIT_OBJECT_DIRECTORY
+ ($GIT_DIR/objects), making sure that it is consistent and
+ complete without referring to objects found in alternate
+ object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES,
+ nor packed GIT archives found in $GIT_DIR/objects/pack;
+ cannot be used with --full.
+
+--full::
+ Check not just objects in GIT_OBJECT_DIRECTORY
+ ($GIT_DIR/objects), but also the ones found in alternate
+ object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES,
+ and in packed GIT archives found in $GIT_DIR/objects/pack
+ and corresponding pack subdirectories in alternate
+ object pools; cannot be used with --standalone.
+
+--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 triggers this check, but it is recommended
+ to check new projects with this flag.
It tests SHA1 and general object sanity, and it does full tracking of
the resulting reachability and everything else. It prints out any
So for example
- git-fsck-cache --unreachable $(cat .git/HEAD)
-
-or, for Cogito users:
-
- git-fsck-cache --unreachable $(cat .git/refs/heads/*)
+ git-fsck-cache --unreachable $(cat .git/HEAD .git/refs/heads/*)
will do quite a _lot_ of verification on the tree. There are a few
extra validity tests to be added (make sure that tree objects are
The database has an object who's sha1 doesn't match the
database value.
This indicates a serious data integrity problem.
- (note: this error occured during early git development when
- the database format changed.)
Environment Variables

- used to specify the cache
+ used to specify the index file of the cache
+GIT_ALTERNATE_OBJECT_DIRECTORIES:
