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

       Comparing blobs or trees that have been replaced with those that replace them will not work properly. And
       using gitreset--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 gitrev-list related to pending objects.

git-hash-object(1), git-rebase(1), and git-filter-repo[1], among other git commands, can be used to
       create replacement objects from existing objects. The --edit option can also be used with gitreplace 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.

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       For example if commit foo has been replaced by commit bar: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

       The following formats are available:

       •   short: <replaced-sha1>

       •   medium: <replaced-sha1> → <replacement-sha1>

       •   long: <replaced-sha1> (<replaced-type>) → <replacement-sha1> (<replacement-type>)

Git 2.48.1                                         07/02/2025                                     GIT-REPLACE(1)

       -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. Use --convert-graft-file to convert a
           $GIT_DIR/info/grafts file and use replace refs instead.

       --convert-graft-file
           Creates graft commits for all entries in $GIT_DIR/info/grafts and deletes that file upon success. The
           purpose is to help users with transitioning off of the now-deprecated graft file.

       -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.
