git-history(1) Git Manual git-history(1)
NAME
git-history - EXPERIMENTAL: Rewrite history
SYNOPSIS
git history fixup <commit> [--dry-run] [--update-refs=(branches|head)] [--reedit-message] [--empty=(drop|keep|abort)]
git history reword <commit> [--dry-run] [--update-refs=(branches|head)]
git history split <commit> [--dry-run] [--update-refs=(branches|head)] [--] [<pathspec>...]
DESCRIPTION
Rewrite history by rearranging or modifying specific commits in the
history.
THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
This command is related to git-rebase(1) in that both commands can be
used to rewrite history. There are a couple of major differences
though:
git-history(1) can work in a bare repository as
they do not need to touch either the index or the worktree. The
fixup subcommand is an exception to this, as it reads staged
changes from the index.
git-history(1) does not execute any githooks(5) at the current
point in time. This may change in the future.
git-history(1) by default updates all branches that are descendants
of the original commit to point to the rewritten commit.
Overall, git-history(1) aims to provide a more opinionated way to
modify your commit history that is simpler to use compared to git-
rebase(1) in general.
Use git-rebase(1) if you want to reapply a range of commits onto a
different base, or interactive rebases if you want to edit a range of
commits at once.
LIMITATIONS
This command does not (yet) work with histories that contain merges.
You should use git-rebase(1) with the --rebase-merges flag instead.
Furthermore, the command does not support operations that can result in
merge conflicts. This limitation is by design as history rewrites are
not intended to be stateful operations. The limitation can be lifted
once (if) Git learns about first-class conflicts.
When using fixup with --empty=drop, dropping the root commit is not yet
supported.
COMMANDS
The following commands are available to rewrite history in different
ways:
fixup <commit>
Apply the currently staged changes to the specified commit. This is
similar in nature to git commit --fixup=<commit> followed by git
rebase --autosquash <commit>~. Changes are applied to the target
commit by performing a three-way merge between the HEAD commit, the
target commit and the tree generated from staged changes.
The commit message and authorship of the target commit are
preserved by default, unless you specify --reedit-message.
If applying the staged changes would result in a conflict, the
command aborts with an error. All branches that are descendants of
the original commit are updated to point to the rewritten history.
reword <commit>
Rewrite the commit message of the specified commit. All the other
details of this commit remain unchanged. This command will spawn an
editor with the current message of that commit.
split <commit> [--] [<pathspec>...]
Interactively split up <commit> into two commits by choosing hunks
introduced by it that will be moved into the new split-out commit.
These hunks will then be written into a new commit that becomes the
parent of the previous commit. The original commit stays intact,
except that its parent will be the newly split-out commit.
The commit messages of the split-up commits will be asked for by
launching the configured editor. Authorship of the commit will be
the same as for the original commit.
If passed, <pathspec> can be used to limit which changes shall be
split out of the original commit. Files not matching any of the
pathspecs will remain part of the original commit. For more
details, see the pathspec entry in gitglossary(7).
It is invalid to select either all or no hunks, as that would lead
to one of the commits becoming empty.
OPTIONS
--dry-run
Do not update any references, but instead print any ref updates in
a format that can be consumed by git-update-ref(1). Necessary new
objects will be written into the repository, so applying these
printed ref updates is generally safe.
--reedit-message
Open an editor to modify the target commit's message.
--empty=(drop|keep|abort)
Control what happens when a commit becomes empty as a result of the
fixup. This can happen in two situations:
o The fixup target itself becomes empty because the staged
changes exactly cancel out all changes introduced by that
commit.
o A descendant commit becomes empty during replay because it
introduced the same change that was just fixed up into an
ancestor.
With drop (the default), empty commits are removed from the
rewritten history. Descendants of a dropped target commit are
replayed directly onto the target's parent. Note that dropping the
root commit is not supported; see LIMITATIONS.
With keep, empty commits are retained in the rewritten history
as-is.
With abort, the command stops with an error if any commit would
become empty.
--update-refs=(branches|head)
Control which references will be updated by the command, if any.
With branches, all local branches that point to commits which are
descendants of the original commit will be rewritten. With head,
only the current HEAD reference will be rewritten. Defaults to
branches.
EXAMPLES
Fixup a commit
$ git log --oneline --stat
abc1234 (HEAD -> main) third
third.txt | 1 +
def5678 second
second.txt | 1 +
ghi9012 first
first.txt | 1 +
$ echo "change" >>unrelated.txt
$ git add unrelated.txt
$ git history fixup ghi9012
$ git log --oneline --stat
jkl3456 (HEAD -> main) third
third.txt | 1 +
mno7890 second
second.txt | 1 +
pqr1234 first
first.txt | 1 +
unrelated.txt | 1 +
The staged addition of unrelated.txt has been incorporated into the
first commit. All descendant commits have been replayed on top of the
rewritten history.
Split a commit
$ git log --stat --oneline
