How to remove a commit from the middle of a branch

Question

I've made some commits and have pushed it to my remote repo. One of those I want to remove. It includes only one binary file, which was changed only in that commit in that branch. How to remove it without harm for later commits?

`git rebase -i TARGET_COMMIT~1` and then don't pick `TARGET_COMMIT` I think would work. — CollinD, Feb 28 '17 at 20:28
In @CollinD solution, you will have to force your push to remote repository (preferred `--force-with-lease`), because your changes won't be possible to fast-forward. If you want to avoid those issues, you can `git revert` this commit. — kolejnik, Feb 28 '17 at 21:12

You can use interactive (-i) rebase to remove a previous commit.

$ git log                          # copy the target commit 

$ git rebase -i <target-commit>~1  # start rebase from the previous commit of target commit

An editor will open with a list of commits, one per line. Each of these lines begins with pick. Comment out your target commit's line (Put # at the start of target commit line).

OR, put drop or d instead of commenting out the line with #.

$ git rebase --continue      # repeat the command until finish rebase

Now, you need to do force (-f) push to remote since git history has been changed!

$ git push -f origin HEAD

What will happen after the last step i.e push -f ?? – AKSHAY SHINGOTE Mar 07 '17 at 09:11
@AKSHAYSHINGOTE your remote (`origin` here) will be updated (removed the commit from git history). – Sajib Khan Mar 07 '17 at 09:38

Nailed it, thanks for this. **NOTE: If you want to be more explicit, you can also use `drop` or `d` instead of commenting out the line with `#`.** – Joshua Pinter Sep 28 '19 at 17:22

Yes, that's right @joshu Pinter. Updated answer. Thanks! – Sajib Khan Sep 28 '19 at 21:03
Is there an alternative that doesn't involve force push, and records this commit "deletion"? – tejasvi88 Oct 20 '20 at 07:25
@tejasvi88 to delete a commit is like changing git history so, there is no alternative way except force push! (so far I know) – Sajib Khan Oct 20 '20 at 07:33
Why no one talk about flag --rebase-merges ? It should be considered in answer, becasuse this solution will remove merge commit between HEAD and target commit+1 – KJanek Jun 25 '21 at 11:01

The flag --rebase-merges should be considered in answer, becasuse accepted solution will remove merge commit between HEAD and target commit~1

Example:

Before any rebase:

f3e07b4 (HEAD -> dev, origin/dev) headCommit
dd3d182 Merged PR 425: added playoutServerUsage
7ed3eb5 added playoutServerUsage
03b52af feat: add Description Series  #targetCommit
0a1217c some_older_commit

git rebase -i target-commit~1

c11fa07 (HEAD -> dev) headCommit
7ed3eb5 added playoutServerUsage
0a1217c some_older_commit

git rebase -i target-commit~1 --rebase-merge
a1943b6 (HEAD -> dev) headCommit
12411a1 Merged PR 425: added playoutServerUsage
7ed3eb5 added playoutServerUsage
0a1217c some_older_commit
Rebase with flag --rebase-merges can be harder and whole process will bo longer (bigger tree), but still we have to locate target commit and change 'pick' to 'drop'

After that I would recommend using

git push --force-with-lease origin HEAD

instead force only.

force vs force-with-lease

PS. It is worth paying attention which commit hashes was changed
