GIT-REPLACE(1)                                               Git Manual                                              GIT-REPLACE(1)

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 [-f] --convert-graft-file
       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       For example if commit foo has been replaced by commit bar: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. 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.

FORMATS
       The following format are available:

       •   short: <replaced sha1>

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

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

CREATING REPLACEMENT 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 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.
