NAME
git-replace - Create, list, delete refs to replace objects
SYNOPSIS
git replace [-f] <object> <replacement>
git replace -d <object>...
git replace -l [<pattern>]
DESCRIPTION
Adds a replace reference in .git/refs/replace/
The name of the replace reference is the SHA1 of the object that is
replaced. The content of the replace reference is the SHA1 of the
replacement object.
Unless -f is given, the replace reference must not yet exist in
.git/refs/replace/ directory.
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For example if commit foo has been replaced by commit bar: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
If an existing replace ref for the same object exists, it will be
overwritten (instead of failing).
-d
Delete existing replace refs for the given objects.
-l <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.
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. And of course things may break if an object of one type is
replaced by an object of another type (for example a blob replaced by a
commit).
