Undo a particular commit in Git that s been pushed to remote repos

Question

What is the simplest way to undo a particular commit that is    not in the head or HEAD Has been pushed to the remote    Because if it is not the latest commit    git reset HEAD   doesn t work  And because it has been pushed to a remote   git rebase -i   and  git rebase --onto   will cause some problem in the remotes    More so  I don t want to modify the history really  If there was bad code  it was there in the history and can be seen  I just want it out in the working copy  and I don t mind a reverse merge commit   In other words  what is the Git equivalent of the following svn commands   svn merge -r 303 295 http   svn example com repos calc trunk   which removes all changes from 295 to 302 by reverse merging all changes in those revisions  as a new commit   svn merge -c -302   trunk   which undoes the 302 commit  of course by adding another commit that reverse merges the changes from that respective commit   I thought it should be a fairly simple operation in Git and a fairly common use case  What else is the point of atomic commits    We have staging stashing and all to ensure the commits are perfectly atomic  shouldn t you be able to undo one or more of those atomic commits easily

Identify the hash of the commit  using git log  then use git revert  lt commit gt  to create a new commit that removes these changes   In a way  git revert is the converse of git cherry-pick -- the latter applies the patch to a branch that s missing it  the former removes it from a branch that has it

Because it has already been pushed  you shouldn t directly manipulate history  git revert will revert specific changes from a commit using a new commit  so as to not manipulate commit history

I don t like the auto-commit that git revert does  so this might be helpful for some   If you just want the modified files not the auto-commit  you can use --no-commit    git revert --no-commit  lt commit hash gt    which is the same as the -n    git revert -n  lt commit hash gt

If the commit you want to revert is a merged commit  has been merged already   then you should either -m 1 or -m 2 option as shown below  This will let git know which parent commit of the merged commit to use  More details can be found HERE    git revert  lt commit gt  -m 1 git revert  lt commit gt  -m 2
