How do I reverse a commit in git

Question

I m not really familiar with how git works  I pushed a commit by mistake and want to revert it  I did a   git reset --hard HEAD 1   Beware Fellow Googlers  This does not only revert the commit  but discards all file changes   and now the project is reverted on my machine  but not on github  If I try to push this code  I get the error  Your branch is behind  origin master  by 1 commit  and can be fast-forwarded   How do I remove this commit from github

This article has an excellent explanation as to how to go about various scenarios  where a commit has been done as well as the push OR just a commit  before the push    http   christoph ruegg name blog git-howto-revert-a-commit-already-pushed-to-a-remote-reposit html  From the article  the easiest command I saw to revert a previous commit by its commit id  was   git revert dd61ab32

Unable to comment on others answers  I ll provide a bit of extra information   If you want to revert the last commit  you can use git revert head  head refers to the most recent commit in your branch   The reason you use head 1 when using reset is that you are telling Git to  remove all changes in the commits after   reset --hard   the commit one before head   head 1    reset is to a commit  revert is on a commit   As AmpT pointed out  you can also use the commit SHA to identify it  rather than counting how far away from head it is  The SHA can be found in the logs  git log  and a variety of other ways   You can also always use any other pointers in Git  e g  a tag or branch  And can also use all of these fun other ways to reference commits https   www kernel org pub software scm git docs git-rev-parse html  specifying revisions

I think you need to push a revert commit  So pull from github again  including the commit you want to revert  then use git revert and push the result   If you don t care about other people s clones of your github repository being broken  you can also delete and recreate the master branch on github after your reset  git push origin  master

git push -f maybe   man git-push will tell more

Or you can try using git revert http   www kernel org pub software scm git docs git-revert html   I think something like git revert HEAD 1 -m 1 will revert your last commit  if it s still the last commit

You can do git push --force but be aware that you are rewriting history and anyone using the repo will have issue with this   If you want to prevent this problem  don t use reset  but instead use git revert
