       git-reset - Reset current HEAD to the specified state

       git reset [-q] [<tree-ish>] [--]	<paths>...
       git reset (--patch | -p)	[<tree-ish>] [--] [<paths>...]
       git reset [--soft | --mixed [-N]	| --hard | --merge | --keep] [-q] [<commit>]

       In the first and	second form, copy entries from <tree-ish> to the
       index. In the third 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>] [--]	<paths>...
	   This	form resets the	index entries for all <paths> to their state
	   at <tree-ish>. (It does not affect the working tree or the current

	   This	means that git reset <paths> is	the opposite of	git add

	   After running git reset <paths> to update the index entry, you can
	   use git-checkout(1) to check	the contents out of the	index to the
	   working tree. Alternatively,	using git-checkout(1) and specifying a
	   commit, 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>] [--] [<paths>...]
	   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 git-add(1) to learn	how to operate the --patch

       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>. If	<mode> is omitted, defaults to
	   "--mixed". The <mode> must be one of	the following:

	       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.

	       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 git-add(1)).

	       Resets the index	and working tree. Any changes to tracked files
	       in the working tree since <commit> are discarded.

	       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.

	       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

       If you want to undo a commit other than the latest on a branch, git-
       revert(1) is your friend.

       -q, --quiet
	   Be quiet, only report errors.

       Undo add

	       $ edit					  (1)
	       $ git add frotz.c filfre.c
	       $ mailx					  (2)
	       $ git reset				  (3)
	       $ git pull git:// 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
	   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
	   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 git-commit(1).

       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 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 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...
	       $ 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 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
	   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 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

	       $ git tag start
	       $ git checkout -b branch1
	       $ edit
	       $ git commit ...				   (1)
	       $ edit
	       $ git checkout -b 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 checkout -b 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 commited	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 is a special notation for the commit that
	   HEAD	used to	be at prior to the original reset commit (1 change
	   ago). See 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.

       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 local change wrt 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

       "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

       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.
