NAME
       git-replace - Create, list, delete refs to replace objects

SYNOPSIS
       git replace [-f]	<object> <replacement>
       git replace [-f]	--edit <object>
       git replace [-f]	--graft	<commit> [<parent>...]
       git replace -d <object>...
       git replace [--format=<format>] [-l [<pattern>]]

DESCRIPTION
       Adds a replace reference	in refs/replace/ namespace.

       The name	of the replace reference is the	SHA-1 of the object that is
       replaced. The content of	the replace reference is the SHA-1 of the
       replacement object.

       The replaced object and the replacement object must be of the same
       type. This restriction can be bypassed using -f.

       Unless -f is given, the replace reference must not yet exist.

       There is	no other restriction on	the replaced and replacement objects.
       Merge commits can be replaced by	non-merge commits and vice versa.

       Replacement references will be used by default by all Git commands
       except those doing reachability traversal (prune, pack transfer and
       fsck).

       It is possible to disable use of	replacement references for any command
       using the --no-replace-objects option just after	git.

       For example if commit foo has been replaced by commit bar:

	   $ git --no-replace-objects cat-file commit foo

       shows information about commit foo, while:

	   $ git cat-file commit foo

       shows information about commit bar.

       The GIT_NO_REPLACE_OBJECTS environment variable can be set to achieve
       the same	effect as the --no-replace-objects option.

OPTIONS
       -f, --force
	   If an existing replace ref for the same object exists, it will be
	   overwritten (instead	of failing).

       -d, --delete
	   Delete existing replace refs	for the	given objects.

       --edit <object>
	   Edit	an object's content interactively. The existing	content	for
	   <object> is pretty-printed into a temporary file, an	editor is
	   launched on the file, and the result	is parsed to create a new
	   object of the same type as <object>.	A replacement ref is then
	   created to replace <object> with the	newly created object. See git-
	   var(1) for details about how	the editor will	be chosen.

       --raw
	   When	editing, provide the raw object	contents rather	than
	   pretty-printed ones.	Currently this only affects trees, which will
	   be shown in their binary form. This is harder to work with, but can
	   help	when repairing a tree that is so corrupted it cannot be
	   pretty-printed. Note	that you may need to configure your editor to
	   cleanly read	and write binary data.

       --graft <commit>	[<parent>...]
	   Create a graft commit. A new	commit is created with the same
	   content as <commit> except that its parents will be [<parent>...]
	   instead of <commit>'s parents. A replacement	ref is then created to
	   replace <commit> with the newly created commit. See
	   contrib/convert-grafts-to-replace-refs.sh for an example script
	   based on this option	that can convert grafts	to replace refs.

       -l <pattern>, --list <pattern>
	   List	replace	refs for objects that match the	given pattern (or all
	   if no pattern is given). Typing "git	replace" without arguments,
	   also	lists all replace refs.

       --format=<format>
	   When	listing, use the specified <format>, which can be one of
	   short, medium and long. When	omitted, the format defaults to	short.

FORMATS
       The following format are	available:

       o   short: <replaced sha1>

       o   medium: <replaced sha1> -> <replacement sha1>

       o   long: <replaced sha1> (<replaced type>) -> <replacement sha1>
	   (<replacement type>)

CREATING REPLACEMENT OBJECTS
       git-filter-branch(1), git-hash-object(1)	and git-rebase(1), among other
       git commands, can be used to create replacement objects from existing
       objects.	The --edit option can also be used with	git replace to create
       a replacement object by editing an existing object.

       If you want to replace many blobs, trees	or commits that	are part of a
       string of commits, you may just want to create a	replacement string of
       commits and then	only replace the commit	at the tip of the target
       string of commits with the commit at the	tip of the replacement string
       of commits.

BUGS
       Comparing blobs or trees	that have been replaced	with those that
       replace them will not work properly. And	using git reset	--hard to go
       back to a replaced commit will move the branch to the replacement
       commit instead of the replaced commit.

       There may be other problems when	using git rev-list related to pending
       objects.
