git-reset(1) |

============ |

|
|
NAME |
|
---- |
|
git-reset - Reset current HEAD to the specified state |
|
|
|
SYNOPSIS |
|
-------- |
|
[verse] |
|
'git reset' [--mixed | --soft | --hard] [-q] [<commit>] |
|
'git reset' [-q] [<commit>] [--] <paths>... |
|
|
|
DESCRIPTION |
|
----------- |
|
Sets the current head to the specified commit and optionally resets the |
|
index and working tree to match. |
|
|
|
This command is useful if you notice some small error in a recent |
|
commit (or set of commits) and want to redo that part without showing |
|
the undo in the history. |
|
|
|
If you want to undo a commit other than the latest on a branch, |
|
linkgit:git-revert[1] is your friend. |
|
|
|
The second form with 'paths' is used to revert selected paths in |
|
the index from a given commit, without moving HEAD. |
|
|
|
|
|
OPTIONS |
|
------- |
|
--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. |
|
|
|
--soft:: |
|
Does not touch the index file nor the working tree at all, but |
|
requires them to be in a good order. This leaves all your changed |
|
files "Changes to be committed", as 'git-status' would |
|
put it. |
|
|
|
--hard:: |
|
Matches the working tree and index to that of the tree being |
|
switched to. Any changes to tracked files in the working tree |
|
since <commit> are lost. |
|
|
|
-q:: |
|
Be quiet, only report errors. |
|
|
|
<commit>:: |
|
Commit to make the current HEAD. If not given defaults to HEAD. |
|
|
|
Examples |
|
-------- |
|
|
|
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 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 commit, making it a topic branch:: |
|
+ |
|
------------ |
|
$ git branch topic/wip <1> |
|
$ git reset --hard HEAD~3 <2> |
|
$ git checkout 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 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 sounds 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 nor 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 merge or pull:: |
|
+ |
|
------------ |
|
$ git pull <1> |
|
Auto-merging nitfol |
|
CONFLICT (content): Merge conflict in nitfol |
|
Automatic merge failed/prevented; fix up by hand |
|
$ 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. |
|
|
|
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 checkout feature ;# you were working in "feature" branch and |
|
$ work work work ;# got interrupted |
|
$ git commit -a -m "snapshot WIP" <1> |
|
$ git checkout master |
|
$ fix fix fix |
|
$ git commit ;# commit with real log |
|
$ git checkout 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. |
|
|
|
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. |
