NAME
----
git-reset - Reset current HEAD to the specified state
SYNOPSIS
--------
[verse]
'git reset' [-q] [<tree-ish>] [--] <pathspec>...
'git reset' [-q] [--pathspec-from-file=<file> [--pathspec-file-nul]] [<tree-ish>]
'git reset' (--patch | -p) [<tree-ish>] [--] [<pathspec>...]
'git reset' [--soft | --mixed [-N] | --hard | --merge | --keep] [-q] [<commit>]
DEPRECATED: 'git reset' [-q] [--stdin [-z]] [<tree-ish>]
DESCRIPTION
-----------
In the first three forms, copy entries from `<tree-ish>` to the index.
In the last form, set the current branch head (`HEAD`) to `<commit>`,
optionally modifying index and working tree to match.
The `<tree-ish>`/`<commit>` defaults to `HEAD` in all forms.
'git reset' [-q] [<tree-ish>] [--] <pathspec>...::
'git reset' [-q] [--pathspec-from-file=<file> [--pathspec-file-nul]] [<tree-ish>]::
These forms reset the index entries for all paths that match the
`<pathspec>` to their state at `<tree-ish>`. (It does not affect
the working tree or the current branch.)
+
This means that `git reset <pathspec>` is the opposite of `git add
<pathspec>`. This command is equivalent to
`git restore [--source=<tree-ish>] --staged <pathspec>...`.
+
After running `git reset <pathspec>` to update the index entry, you can
use linkgit:git-restore[1] to check the contents out of the index to
the working tree. Alternatively, using linkgit:git-restore[1]
and specifying a commit with `--source`, you
can copy the contents of a path out of a commit to the index and to the
working tree in one go.
'git reset' (--patch | -p) [<tree-ish>] [--] [<pathspec>...]::
Interactively select hunks in the difference between the index
and `<tree-ish>` (defaults to `HEAD`). The chosen hunks are applied
in reverse to the index.
+
This means that `git reset -p` is the opposite of `git add -p`, i.e.
you can use it to selectively reset hunks. See the ``Interactive Mode''
section of linkgit:git-add[1] to learn how to operate the `--patch` mode.
'git reset' [<mode>] [<commit>]::
This form resets the current branch head to `<commit>` and
possibly updates the index (resetting it to the tree of `<commit>`) and
the working tree depending on `<mode>`. Before the operation, `ORIG_HEAD`
is set to the tip of the current branch. If `<mode>` is omitted,
defaults to `--mixed`. The `<mode>` must be one of the following:
+
--
--soft::
Does not touch the index file or the working tree at all (but
resets the head to `<commit>`, just like all modes do). This leaves
all your changed files "Changes to be committed", as `git status`
would put it.
--mixed::
Resets the index but not the working tree (i.e., the changed files
are preserved but not marked for commit) and reports what has not
been updated. This is the default action.
+
If `-N` is specified, removed paths are marked as intent-to-add (see
linkgit:git-add[1]).
--hard::
Resets the index and working tree. Any changes to tracked files in the
working tree since `<commit>` are discarded. Any untracked files or
directories in the way of writing any tracked files are simply deleted.
--merge::
Resets the index and updates the files in the working tree that are
different between `<commit>` and `HEAD`, but keeps those which are
different between the index and working tree (i.e. which have changes
which have not been added).
If a file that is different between `<commit>` and the index has
unstaged changes, reset is aborted.
+
In other words, `--merge` does something like a `git read-tree -u -m <commit>`,
but carries forward unmerged index entries.
--keep::
Resets index entries and updates files in the working tree that are
different between `<commit>` and `HEAD`.
If a file that is different between `<commit>` and `HEAD` has local
changes, reset is aborted.
--[no-]recurse-submodules::
When the working tree is updated, using --recurse-submodules will
also recursively reset the working tree of all active submodules
according to the commit recorded in the superproject, also setting
the submodules' HEAD to be detached at that commit.
--
See "Reset, restore and revert" in linkgit:git[1] for the differences
between the three commands.
OPTIONS
-------
-q::
--quiet::
Be quiet, only report errors.
--refresh::
--no-refresh::
Refresh the index after a mixed reset. Enabled by default.
--pathspec-from-file=<file>::
Pathspec is passed in `<file>` instead of commandline args. If
`<file>` is exactly `-` then standard input is used. Pathspec
elements are separated by LF or CR/LF. Pathspec elements can be
quoted as explained for the configuration variable `core.quotePath`
(see linkgit:git-config[1]). See also `--pathspec-file-nul` and
global `--literal-pathspecs`.
--pathspec-file-nul::
Only meaningful with `--pathspec-from-file`. Pathspec elements are
separated with NUL character and all other characters are taken
literally (including newlines and quotes).
\--::
Do not interpret any more arguments as options.
<pathspec>...::
Limits the paths affected by the operation.
+
For more details, see the 'pathspec' entry in linkgit:gitglossary[7].
--stdin::
DEPRECATED (use `--pathspec-from-file=-` instead): Instead of taking
list of paths from the command line, read list of paths from the
standard input. Paths are separated by LF (i.e. one path per line) by
default.
-z::
DEPRECATED (use `--pathspec-file-nul` instead): Only meaningful with
`--stdin`; paths are separated with NUL character instead of LF.
EXAMPLES
--------
Undo add::
+
------------
$ edit <1>
$ git add frotz.c filfre.c
$ mailx <2>
$ git reset <3>
$ git pull git://info.example.com/ nitfol <4>
------------
+
<1> You are happily working on something, and find the changes
in these files are in good order. You do not want to see them
when you run `git diff`, because you plan to work on other files
and changes with these files are distracting.
<2> Somebody asks you to pull, and the changes sound worthy of merging.
<3> However, you already dirtied the index (i.e. your index does
not match the `HEAD` commit). But you know the pull you are going
to make does not affect `frotz.c` or `filfre.c`, so you revert the
index changes for these two files. Your changes in working tree
remain there.
<4> Then you can pull and merge, leaving `frotz.c` and `filfre.c`
changes still in the working tree.
Undo a commit and redo::
+
------------
$ git commit ...
$ git reset --soft HEAD^ <1>
$ edit <2>
$ git commit -a -c ORIG_HEAD <3>
------------
+
<1> This is most often done when you remembered what you
just committed is incomplete, or you misspelled your commit
message, or both. Leaves working tree as it was before "reset".
<2> Make corrections to working tree files.
<3> "reset" copies the old head to `.git/ORIG_HEAD`; redo the
commit by starting with its log message. If you do not need to
edit the message further, you can give `-C` option instead.
+
See also the `--amend` option to linkgit:git-commit[1].
Undo a commit, making it a topic branch::
+
------------
$ git branch topic/wip <1>
$ git reset --hard HEAD~3 <2>
$ git switch topic/wip <3>
------------
+
<1> You have made some commits, but realize they were premature
to be in the `master` branch. You want to continue polishing
them in a topic branch, so create `topic/wip` branch off of the
current `HEAD`.
<2> Rewind the master branch to get rid of those three commits.
<3> Switch to `topic/wip` branch and keep working.
Undo commits permanently::
+
------------
$ git commit ...
$ git reset --hard HEAD~3 <1>
------------
+
<1> The last three commits (`HEAD`, `HEAD^`, and `HEAD~2`) were bad
and you do not want to ever see them again. Do *not* do this if
you have already given these commits to somebody else. (See the
"RECOVERING FROM UPSTREAM REBASE" section in linkgit:git-rebase[1]
for the implications of doing so.)
Undo a merge or pull::
+
------------
$ git pull <1>
Auto-merging nitfol
CONFLICT (content): Merge conflict in nitfol
Automatic merge failed; fix conflicts and then commit the result.
$ git reset --hard <2>
$ git pull . topic/branch <3>
Updating from 41223... to 13134...
Fast-forward
$ git reset --hard ORIG_HEAD <4>
------------
+
<1> Try to update from the upstream resulted in a lot of
conflicts; you were not ready to spend a lot of time merging
right now, so you decide to do that later.
<2> "pull" has not made merge commit, so `git reset --hard`
which is a synonym for `git reset --hard HEAD` clears the mess
from the index file and the working tree.
<3> Merge a topic branch into the current branch, which resulted
in a fast-forward.
<4> But you decided that the topic branch is not ready for public
consumption yet. "pull" or "merge" always leaves the original
tip of the current branch in `ORIG_HEAD`, so resetting hard to it
brings your index file and the working tree back to that state,
and resets the tip of the branch to that commit.
Undo a merge or pull inside a dirty working tree::
+
------------
$ git pull <1>
Auto-merging nitfol
Merge made by recursive.
nitfol | 20 +++++----
...
$ git reset --merge ORIG_HEAD <2>
------------
+
<1> Even if you may have local modifications in your
working tree, you can safely say `git pull` when you know
that the change in the other branch does not overlap with
them.
<2> After inspecting the result of the merge, you may find
that the change in the other branch is unsatisfactory. Running
`git reset --hard ORIG_HEAD` will let you go back to where you
were, but it will discard your local changes, which you do not
want. `git reset --merge` keeps your local changes.
Interrupted workflow::
+
Suppose you are interrupted by an urgent fix request while you
are in the middle of a large change. The files in your
working tree are not in any shape to be committed yet, but you
need to get to the other branch for a quick bugfix.
+
------------
$ git switch feature ;# you were working in "feature" branch and
$ work work work ;# got interrupted
$ git commit -a -m "snapshot WIP" <1>
$ git switch master
$ fix fix fix
$ git commit ;# commit with real log
$ git switch feature
$ git reset --soft HEAD^ ;# go back to WIP state <2>
$ git reset <3>
------------
+
<1> This commit will get blown away so a throw-away log message is OK.
<2> This removes the 'WIP' commit from the commit history, and sets
your working tree to the state just before you made that snapshot.
<3> At this point the index file still has all the WIP changes you
committed as 'snapshot WIP'. This updates the index to show your
WIP files as uncommitted.
+
See also linkgit:git-stash[1].
Reset a single file in the index::
+
Suppose you have added a file to your index, but later decide you do not
want to add it to your commit. You can remove the file from the index
while keeping your changes with git reset.
+
------------
$ git reset -- frotz.c <1>
$ git commit -m "Commit files in index" <2>
$ git add frotz.c <3>
------------
+
<1> This removes the file from the index while keeping it in the working
directory.
<2> This commits all other changes in the index.
<3> Adds the file to the index again.
Keep changes in working tree while discarding some previous commits::
+
Suppose you are working on something and you commit it, and then you
continue working a bit more, but now you think that what you have in
your working tree should be in another branch that has nothing to do
with what you committed previously. You can start a new branch and
reset it while keeping the changes in your working tree.
+
------------
$ git tag start
$ git switch -c branch1
$ edit
$ git commit ... <1>
$ edit
$ git switch -c branch2 <2>
$ git reset --keep start <3>
------------
+
<1> This commits your first edits in `branch1`.
<2> In the ideal world, you could have realized that the earlier
commit did not belong to the new topic when you created and switched
to `branch2` (i.e. `git switch -c branch2 start`), but nobody is
perfect.
<3> But you can use `reset --keep` to remove the unwanted commit after
you switched to `branch2`.
Split a commit apart into a sequence of commits::
+
Suppose that you have created lots of logically separate changes and committed
them together. Then, later you decide that it might be better to have each
logical chunk associated with its own commit. You can use git reset to rewind
history without changing the contents of your local files, and then successively
use `git add -p` to interactively select which hunks to include into each commit,
using `git commit -c` to pre-populate the commit message.
+
------------
$ git reset -N HEAD^ <1>
$ git add -p <2>
$ git diff --cached <3>
$ git commit -c HEAD@{1} <4>
... <5>
$ git add ... <6>
$ git diff --cached <7>
$ git commit ... <8>
------------
+
<1> First, reset the history back one commit so that we remove the original
commit, but leave the working tree with all the changes. The -N ensures
that any new files added with `HEAD` are still marked so that `git add -p`
will find them.
<2> Next, we interactively select diff hunks to add using the `git add -p`
facility. This will ask you about each diff hunk in sequence and you can
use simple commands such as "yes, include this", "No don't include this"
or even the very powerful "edit" facility.
<3> Once satisfied with the hunks you want to include, you should verify what
has been prepared for the first commit by using `git diff --cached`. This
shows all the changes that have been moved into the index and are about
to be committed.
<4> Next, commit the changes stored in the index. The `-c` option specifies to
pre-populate the commit message from the original message that you started
with in the first commit. This is helpful to avoid retyping it. The
`HEAD@{1}` is a special notation for the commit that `HEAD` used to be at
prior to the original reset commit (1 change ago).
See linkgit:git-reflog[1] for more details. You may also use any other
valid commit reference.
<5> You can repeat steps 2-4 multiple times to break the original code into
any number of commits.
<6> Now you've split out many of the changes into their own commits, and might
no longer use the patch mode of `git add`, in order to select all remaining
uncommitted changes.
<7> Once again, check to verify that you've included what you want to. You may
also wish to verify that git diff doesn't show any remaining changes to be
committed later.
<8> And finally create the final commit.
DISCUSSION
----------
The tables below show what happens when running:
----------
git reset --option target
----------
to reset the `HEAD` to another commit (`target`) with the different
reset options depending on the state of the files.
In these tables, `A`, `B`, `C` and `D` are some different states of a
file. For example, the first line of the first table means that if a
file is in state `A` in the working tree, in state `B` in the index, in
state `C` in `HEAD` and in state `D` in the target, then `git reset --soft
target` will leave the file in the working tree in state `A` and in the
index in state `B`. It resets (i.e. moves) the `HEAD` (i.e. the tip of
the current branch, if you are on one) to `target` (which has the file
in state `D`).

`reset --merge` is meant to be used when resetting out of a conflicted
merge. Any mergy operation guarantees that the working tree file that is
involved in the merge does not have a local change with respect to the index
before it starts, and that it writes the result out to the working tree. So if
we see some difference between the index and the target and also
between the index and the working tree, then it means that we are not
resetting out from a state that a mergy operation left after failing
with a conflict. That is why we disallow `--merge` option in this case.
`reset --keep` is meant to be used when removing some of the last
commits in the current branch while keeping changes in the working
tree. If there could be conflicts between the changes in the commit we
want to remove and the changes in the working tree we want to keep,
the reset is disallowed. That's why it is disallowed if there are both
changes between the working tree and `HEAD`, and between `HEAD` and the
target. To be safe, it is also disallowed when there are unmerged
entries.
The following tables show what happens when there are unmerged
entries:
....
working index HEAD target working index HEAD
----------------------------------------------------
X U A B --soft (disallowed)
--mixed X B B
--hard B B B
--merge B B B
--keep (disallowed)
....
....
working index HEAD target working index HEAD
----------------------------------------------------
X U A A --soft (disallowed)
--mixed X A A
--hard A A A
--merge A A A
--keep (disallowed)
....
`X` means any state and `U` means an unmerged index.
