Git: Reverting multiple bad commits which are already pushed to a central repository

Here is the case:

I pushed multiple bad commits into a central repository and now I wanted to roll back all of them.

Step1 : check git log and identify your last good commit or till where you wanted to roll back.

$ git log --oneline

5ff2aee commit1 - bad commit

8516637 commit2- bad commit

64db1b7 commit3 - bad commit

6897d4b commit4 - bad commit

6974cb5 commit5 - this is my last good commit

79e63c6 commit6

6cd2939 commit7

d39ae18 commit8

Step2: Do reset hard till your last good commit.

$ git reset --hard 6974cb5

Step3: verify git log

$ git log --oneline

6974cb5 commit5 - this is my last good commit

79e63c6 commit6

6cd2939 commit7

d39ae18 commit8

Step 4: Do force push to central repo

$ git push origin <master repo> -f
