DESCRIPTION
-----------
the undo in the history.
If you want to undo a commit other than the latest on a branch,
-gitlink:git-revert[1] is your friend.
+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 (ie, the changed files
+ 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 "Updated but not checked in", as gitlink:git-status[1] would
+ 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-ish> are lost.
+ since <commit> are lost.
+
+-q::
+ Be quiet, only report errors.
-<commit-ish>::
- Commit to make the current HEAD.
+<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>
-
+$ 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.
+<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>
-
+$ 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.
-------------
Undo a commit, making it a topic branch::
+
------------
-$ git branch topic/wip <1>
-$ git reset --hard HEAD~3 <2>
-$ git checkout topic/wip <3>
-
+$ 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 update-index::
+Undo add::
+
------------
-$ edit <1>
-$ git-update-index frotz.c filfre.c
-$ mailx <2>
-$ git reset <3>
-$ git pull git://info.example.com/ nitfol <4>

+$ 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.

+<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
+<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>
-Trying really trivial in-index merge...
-fatal: Merge requires file-level merging
-Nope.
-...
+$ git pull <1>

+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.
-
-$ git pull . topic/branch <3>
-Updating from 41223... to 13134...

-<4> but you decided that the topic branch is not ready for public
+<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::
+
------------
$ git checkout feature ;# you were working in "feature" branch and
$ work work work ;# got interrupted
-$ git commit -a -m 'snapshot WIP' <1>
+$ 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>
-
+$ 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> After <2>, the index file still has all the WIP changes you
- committed in <1>. This sets it to the last commit you were
- basing the WIP changes on.
+<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.
