1git-reset(1) 2============ 3 4NAME 5---- 6git-reset - Reset current HEAD to the specified state 7 8SYNOPSIS 9-------- 10[verse] 11'git-reset' [--mixed | --soft | --hard] [<commit>] 12'git-reset' [--mixed] <commit> [--] <paths>... 13 14DESCRIPTION 15----------- 16Sets the current head to the specified commit and optionally resets the 17index and working tree to match. 18 19This command is useful if you notice some small error in a recent 20commit (or set of commits) and want to redo that part without showing 21the undo in the history. 22 23If you want to undo a commit other than the latest on a branch, 24gitlink:git-revert[1] is your friend. 25 26The second form with 'paths' is used to revert selected paths in 27the index from a given commit, without moving HEAD. 28 29 30OPTIONS 31------- 32--mixed:: 33 Resets the index but not the working tree (i.e., the changed files 34 are preserved but not marked for commit) and reports what has not 35 been updated. This is the default action. 36 37--soft:: 38 Does not touch the index file nor the working tree at all, but 39 requires them to be in a good order. This leaves all your changed 40 files "Added but not yet committed", as gitlink:git-status[1] would 41 put it. 42 43--hard:: 44 Matches the working tree and index to that of the tree being 45 switched to. Any changes to tracked files in the working tree 46 since <commit> are lost. 47 48<commit>:: 49 Commit to make the current HEAD. 50 51Examples 52-------- 53 54Undo a commit and redo:: 55+ 56------------ 57$ git commit ... 58$ git reset --soft HEAD^ <1> 59$ edit <2> 60$ git commit -a -c ORIG_HEAD <3> 61------------ 62+ 63<1> This is most often done when you remembered what you 64just committed is incomplete, or you misspelled your commit 65message, or both. Leaves working tree as it was before "reset". 66<2> make corrections to working tree files. 67<3> "reset" copies the old head to .git/ORIG_HEAD; redo the 68commit by starting with its log message. If you do not need to 69edit the message further, you can give -C option instead. 70+ 71See also the --amend option to gitlink:git-commit[1]. 72 73Undo commits permanently:: 74+ 75------------ 76$ git commit ... 77$ git reset --hard HEAD~3 <1> 78------------ 79+ 80<1> The last three commits (HEAD, HEAD^, and HEAD~2) were bad 81and you do not want to ever see them again. Do *not* do this if 82you have already given these commits to somebody else. 83 84Undo a commit, making it a topic branch:: 85+ 86------------ 87$ git branch topic/wip <1> 88$ git reset --hard HEAD~3 <2> 89$ git checkout topic/wip <3> 90------------ 91+ 92<1> You have made some commits, but realize they were premature 93to be in the "master" branch. You want to continue polishing 94them in a topic branch, so create "topic/wip" branch off of the 95current HEAD. 96<2> Rewind the master branch to get rid of those three commits. 97<3> Switch to "topic/wip" branch and keep working. 98 99Undo add:: 100+ 101------------ 102$ edit <1> 103$ git add frotz.c filfre.c 104$ mailx <2> 105$ git reset <3> 106$ git pull git://info.example.com/ nitfol <4> 107------------ 108+ 109<1> you are happily working on something, and find the changes 110in these files are in good order. You do not want to see them 111when you run "git diff", because you plan to work on other files 112and changes with these files are distracting. 113<2> somebody asks you to pull, and the changes sounds worthy of merging. 114<3> however, you already dirtied the index (i.e. your index does 115not match the HEAD commit). But you know the pull you are going 116to make does not affect frotz.c nor filfre.c, so you revert the 117index changes for these two files. Your changes in working tree 118remain there. 119<4> then you can pull and merge, leaving frotz.c and filfre.c 120changes still in the working tree. 121 122Undo a merge or pull:: 123+ 124------------ 125$ git pull <1> 126Auto-merging nitfol 127CONFLICT (content): Merge conflict in nitfol 128Automatic merge failed/prevented; fix up by hand 129$ git reset --hard <2> 130$ git pull . topic/branch <3> 131Updating from 41223... to 13134... 132Fast forward 133$ git reset --hard ORIG_HEAD <4> 134------------ 135+ 136<1> try to update from the upstream resulted in a lot of 137conflicts; you were not ready to spend a lot of time merging 138right now, so you decide to do that later. 139<2> "pull" has not made merge commit, so "git reset --hard" 140which is a synonym for "git reset --hard HEAD" clears the mess 141from the index file and the working tree. 142<3> merge a topic branch into the current branch, which resulted 143in a fast forward. 144<4> but you decided that the topic branch is not ready for public 145consumption yet. "pull" or "merge" always leaves the original 146tip of the current branch in ORIG_HEAD, so resetting hard to it 147brings your index file and the working tree back to that state, 148and resets the tip of the branch to that commit. 149 150Interrupted workflow:: 151+ 152Suppose you are interrupted by an urgent fix request while you 153are in the middle of a large change. The files in your 154working tree are not in any shape to be committed yet, but you 155need to get to the other branch for a quick bugfix. 156+ 157------------ 158$ git checkout feature ;# you were working in "feature" branch and 159$ work work work ;# got interrupted 160$ git commit -a -m 'snapshot WIP' <1> 161$ git checkout master 162$ fix fix fix 163$ git commit ;# commit with real log 164$ git checkout feature 165$ git reset --soft HEAD^ ;# go back to WIP state <2> 166$ git reset <3> 167------------ 168+ 169<1> This commit will get blown away so a throw-away log message is OK. 170<2> This removes the 'WIP' commit from the commit history, and sets 171 your working tree to the state just before you made that snapshot. 172<3> At this point the index file still has all the WIP changes you 173 committed as 'snapshot WIP'. This updates the index to show your 174 WIP files as uncommitted. 175 176Author 177------ 178Written by Junio C Hamano <junkio@cox.net> and Linus Torvalds <torvalds@osdl.org> 179 180Documentation 181-------------- 182Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>. 183 184GIT 185--- 186Part of the gitlink:git[7] suite
