git-reset(1)
|
|
============
|
|
|
|
NAME
|
|
----
|
|
git-reset - Reset current HEAD to the specified state.
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-reset' [--mixed | --soft | --hard] [<commit-ish>]
|
|
|
|
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,
|
|
gitlink:git-revert[1] is your friend.
|
|
|
|
OPTIONS
|
|
-------
|
|
--mixed::
|
|
Resets the index but not the working tree (ie, 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
|
|
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.
|
|
|
|
<commit-ish>::
|
|
Commit to make the current 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.
|
|
------------
|
|
|
|
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.
|
|
------------
|
|
|
|
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 update-index::
|
|
+
|
|
------------
|
|
$ edit <1>
|
|
$ git-update-index 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.
